__TOC__

=== Introduction to ROCK 5 Debian ===

This guide is available for official ROCK 5 Debian images.

ROCK 5 Debian is an easy to use desktop system. While working with ROCK 5 Debian, you will find it do well on playing music, Internet, BT, AI and so on.

ROCK 5 Debian uses '''systemd''' to manage system.

Command prepended by $ means the command may be executed by an unprivileged user. And command prepended by # means the command may be executed by an privileged user. But the symbol, $ or #, is not part of the command.

=== List of boards supported ===

* ROCK 5B

=== Access from the Host PC/Laptop ===

==== Option 1: HDMI monitor and Mouse ====

You would see Desktop on HDMI monitor.

==== Option 2: Serial console ====

See [[rock5/dev/serial-console | Serial Console]]

==== Option 3: SSH ====

SSH server is enabled on port 22 of ROCK 5 default image.

Please use [https://angryip.org/ angryip] to find your board IP address.

$ ping ip-of-device
$ ssh rock@ip-of-device

=== Default User Account ===

Non-root User:

User Name : rock
Password : rock

=== Switch to root user ===

rock is sudo user and switch to root can be done with the following command as user rock:

sudo su

For example:

rock@rock-5b:~$
rock@rock-5b:~$ sudo su
[sudo] password for rock:
root@rock-5b:/home/rock#

There is no password for root user by default. You can set the password via 'passwd root'.

root@rock-5b:/home/rock# passwd root
New password:
Retype new password:
passwd: password updated successfully
root@rock-5b:/home/rock#

==== 5B LED ====
On ROCK 5B one blue LED is configured as LED class device.

You can control it via <code>/sys/class/leds/blue:status</code>

The default status of the three on board led is flash

=== RTC Device ===
ROCK 5B is equipped with one RTC IC hym8563.

Firstly, plug in RTC battery to give power to RTC IC. Please note that we should keep the RTC battery in the RTC connector.

Plug in power adaper to power on ROCK 5B.

And confirm that the rtc hym8563 device is created.

root@rock-5b:/home/rock# dmesg | grep rtc
[ 6.407133] rtc-hym8563 6-0051: rtc information is valid

==== 5B Ethernet ====

ROCK 5B is equipped with one 2.5G Ethernet port.
You can use a network cable (one end connected to the external network port or route) to connect your ROCK 5B to the network.
The ROCK 5B will automatically configure the network for your surfing on the Internet.

===== Manually configure Ethernet =====

* Switch to super user mode by command
$ sudo su

* Check whether the Ethernet is normal by command, ifconfig, which would show us a network card, eth0 or enP4p65s0 , and the Ethernet IP address. Also, use tool, ping, to connect to a normal domain.

$ ifconfig
$ ping www.baidu.com

* If failed to connect to a normal domain. , try

$ sudo dhclient eth0
or
$ sudo dhclient enP4p65s0

</div> 
</div>

=== WiFi ===
ROCK 5 Model B doesn't come with on board WiFi/BT. Currently the following WiFi Cards are tested and supported by the ROCK 5 Model B.

===== Radxa APT =====

Radxa APT source includes stable one and testing one. Stable source includes stable packages while testing source includes latest but maybe unstable packages.

Radxa APT stable source is added by default while testing source is not added.

You can uncomment line like "deb http://apt.radxa.com/bullseye-testing/ bullseye main" in file /etc/apt/sources.list.d/apt-radxa-com.list to add testing source.

See file /etc/apt/sources.list.d/apt-radxa-com.list

deb http://apt.radxa.com/bullseye-stable/ bullseye main
deb http://apt.radxa.com/bullseye-testing/ bullseye main

After adding testing source, you need to update APT and install your needed packages.

$ sudo apt-get update

For more detail about Radxa APT, please see [[rock5/linux/radxa-apt | Radxa APT]].

ROCK 5B has a M.2 E Key with PCIe 2.1 1-lanes, SATA, SDIO, UART support.

It can use a breakout board to make M.2 E-key to SATA.

=== Requirement ===

* ROCK 5B
* M.2 E-key to SATA breakout board
* SATA Cable

[[File:E-key-to-sata.jpg | 300 px]]
[[File:Sata_cable.png | 300 px]]

=== Hardware connection ===

About SATA power cable, yellow is 12V, red is 5V, and black is GND.

If you use SSD, only 5V power from 40 pin are required as follow.

[[File:SSD-connection.jpg | 300 px]]

If you use HDD, 5V and 12V power supply are required as follow.

Here I supply 12V via digital power supply, 5V is still supplied from 40 pin.

[[File:HDD-connection.jpg | 300 px]]

=== Software configuration ===

Add one line to file /boot/config.txt. Like this.

dtoverlay=rock-5b-sata

And then execute command.

update_extlinux.sh

Reboot the device, you would see your devices with command '''lsblk'''.

rock@rock-5b:~$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:48 0 149.1G 0 disk
mmcblk1 179:0 0 14.6G 0 disk
├─mmcblk1p1 179:1 0 512M 0 part
└─mmcblk1p2 179:2 0 14.1G 0 part /
mmcblk1boot0 179:32 0 4M 1 disk
mmcblk1boot1 179:64 0 4M 1 disk

You can test read and write speed with command '''dd''' or '''fio''', but only if you '''protect your data.'''

[[rockpi4 | ROCK Pi 4]] > [[rockpi4/dev | Development]] > [[Rockpi4/dev/use-uart-with-kernel-5.10 | Use Uart with Kernel 5.10]]

===Description===

If you want to use uart with Kernel 5.10 in ROCK Pi 4. You'd better follow these steps.

==== Install essential package ====

sudo apt-get install -y rockpi4-dtbo

==== UART ====

Modify file /boot/hw_intfc.conf. Set "on" to enable the optional hardware interfaces while set "off" to disable.

intfc:uart2=on
intfc:uart4=on

And add "#" to line "intfc:dtoverlay=console-on-ttyS2"

#intfc:dtoverlay=console-on-ttyS2
#intfc:dtoverlay=console-on-ttyS4

but now, the uart2 can still be used as a debug port with system log. If you don't want to output kernel messages, you can disable it as follow.

Modify file /boot/extlinux/extlinux.conf.
append earlyprintk console=ttyFIQ0,1500000n8 rw init=/sbin/init rootfstype=ext4 rootwait root=UUID=8650cdca-49b0-4431-9667-5c639f6bab89 console=ttyS2,1500000n8
Delete strings '''console=ttyFIQ0,1500000n8''' and '''console=ttyS2,1500000n8''' in this line.
append earlyprintk rw init=/sbin/init rootfstype=ext4 rootwait root=UUID=8650cdca-49b0-4431-9667-5c639f6bab89

__TOC__

== Work with ROCK 3 Debian ==

=== Introduction to ROCK 3 Debian ===

This guide is available for official ROCK 3 Debian images.

ROCK 3 Debian is an easy to use desktop system. While working with ROCK 3 Debian, you will find it do well on playing music, Internet, Bluetooth, AI and so on.

ROCK 3 Debian uses '''systemd''' to manage system.

Command prepended by $ means the command may be executed by an unprivileged user. And command prepended by # means the command may be executed by an privileged user. But the symbol, $ or #, is not part of the command.

=== List of boards supported ===

* ROCK 3A
* ROCK 3B
* Radxa E23
* Radxa E25
* Radxa CM3 IO

=== Access from the Host PC/Laptop ===

==== Option 1: Serial console ====

See [[rock3/dev/serial-console | Serial Console]]

==== Option 2: SSH ====

SSH server is enabled on port 22 of ROCK 3 default image.

Please use [https://angryip.org/ angryip] to find your board IP address.

$ ping ip-of-device
$ ssh rock@ip-of-device

=== Debian Default User Account ===

Non-root User:

User Name : rock
Password : rock

|}

=== Radxa APT ===

Radxa APT source includes stable one and testing one. Stable source includes stable packages while testing source includes latest but maybe unstable packages.

Radxa APT stable source is added by default while testing source is not added.

You can uncomment line like "deb http://apt.radxa.com/buster-testing/ buster main" in file /etc/apt/sources.list.d/apt-radxa-com.list to add testing source.

See file /etc/apt/sources.list.d/apt-radxa-com.list

deb http://apt.radxa.com/buster-stable/ buster main
deb http://apt.radxa.com/buster-testing/ buster main

After adding testing source, you need to update APT and install your needed packages.

$ sudo apt-get update

For more detail about Radxa APT, please see [[rock3/radxa-apt | Radxa APT]].

=== Upgrade necessary packages ===

Here is the example of upgrading rockchip-overlay and kernel packages.
Pakcage linux-4.19-rock-3-latest provides the latest ROCK 3 kernel packages.

$ sudo apt-get update
$ sudo apt-get install -y rockchip-overlay
$ sudo apt-get install -y linux-4.19-rock-3-latest

=== Check DDR size ===

ROCK 3 comes in several different DDR sizes, such as 1G, 2G, 4G, 8G, etc.
Here shows 8GB RAM on ROCK 3A.

root@rock-3a:~# free -h
total used free shared buff/cache available
Mem: '''7.4Gi''' 72Mi 7.1Gi 16Mi 182Mi 7.2Gi
Swap: 0B 0B 0B

=== Storage device ===

* eMMC: /dev/mmcblk0
* uSD Card: /dev/mmcblk1
* NVME M.2 SDD: /dev/nvme0n1

=== NPU ===

SoC RK3566/RK3568 is equipped with 0.8TOPS NPU.
See [[rock3/dev/npu-run-test | NPU Run Test]] to test it on your ROCK 3 boards.

=== <span id="gpio">General purpose input-output (GPIO) </span> ===

* ROCK 3A has one 40-pin expansion header. To control them, see [[rock3/hardware/rock3a-gpio | ROCK 3A GPIO ]].

=== <span id="common_hardware_interface">Common Hardware Interfaces, I2C, PWM, SPI, UART, CAN, etc</span> ===

The ROCK 3 system images use configuration file /boot/uEnv.txt.

'''Warning: Remember there is only one line including item "overlays=" in file /boot/uEnv.txt.'''

To enable I2C, PWM, SPI, UART, CAN, etc, please see '''RK3566/RK3568 Available Overlay (ROCK 3A, ROCK 3B, Radxa CM3)''' part of [[rock3/Debian/device-tree-overlays | Device Tree Overlays]]

=== Test RTC Device ===

ROCK 3A is equipped with one RTC IC hym8563.

Firstly, plug in [[rock3/hardware/rtc | RTC battery]] to give power to RTC IC. Please note that we should keep the RTC battery in the RTC connector.

Plug in power adaper to power on ROCK 3A.

And confirm that the rtc hym8563 device is created.

root@rock3a:~# dmesg | grep rtc
[ 1.128345] rk808-rtc rk808-rtc: registered as rtc0
[ 1.130163] rk808-rtc rk808-rtc: setting system clock to 2017-08-04 09:00:05 UTC (1501837205)
[ 2.801453] rtc-hym8563 5-0051: rtc core: registered hym8563 as rtc1

Secondly, use the following commands to set the system time and synchronize it to rtc1.

root@rock3a:~# date -s "2021-08-17 20:00:00"
root@rock3a:~# hwclock -w -f /dev/rtc1
root@rock3a:~# hwclock -r -f /dev/rtc1
2021-08-17 20:00:04.745124+00:00
root@rock3a:~# poweroff

and then remove the power adapter.

Finally, 10 minutes later we power on ROCK 3A via Type-C Port and check the rtc clock.

root@rock3a:~# hwclock -r -f /dev/rtc1
2021-08-17 20:10:14.745124+00:00

We see that rtc runs about 10 minutes also. That's good.

=== Test Audio Player===

Download a wav audio file, and use the command to test the HP player.

$ amixer -c 1 cset numid=1 3
numid=1,iface=MIXER,name='Playback Path'
; type=ENUMERATED,access=rw------,values=1,items=11
; Item #0 'OFF'
; Item #1 'RCV'
; Item #2 'SPK'
; Item #3 'HP'
; Item #4 'HP_NO_MIC'
; Item #5 'BT'
; Item #6 'SPK_HP'
; Item #7 'RING_SPK'
; Item #8 'RING_HP'
; Item #9 'RING_HP_NO_MIC'
; Item #10 'RING_SPK_HP'
: values=3

$ aplay -D plughw:1,0 test.wav
Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

To test the Mic recording, please follow：
$ amixer -c 1 cset numid=2 1
$ arecord -Dhw:1,0 -d 10 -f cd -r 44100 -c 2 -t wav ./mic_test.wav #this is a record command
Recording WAVE './mic_test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
$ aplay -D plughw:1,0 mic_test.wav

=== Test USB Host Ports ===

There are two USB 2.0 host ports and two USB 3.0 host ports.

Plug in U Disk and fire command ''lsblk''. Here /dev/sda is related to U Disk.

<pre>
root@rock-3a:~# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 1 14.4G 0 disk
|-sda1 8:1 1 200M 0 part
`-sda2 8:2 1 14.2G 0 part
mmcblk0 179:0 0 14.5G 0 disk
|-mmcblk0p1 179:1 0 512M 0 part /boot

mmcblk0boot0 179:32 0 4M 1 disk
mmcblk0boot1 179:64 0 4M 1 disk
</pre>

Mount U Disk.

<pre>
root@rock-3a:~# mount /dev/sda2 /mnt/
</pre>

Confirm that U Disk is mounted.

<pre>
root@rock-3a:~# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 1 14.4G 0 disk
|-sda1 8:1 1 200M 0 part

mmcblk0boot0 179:32 0 4M 1 disk
mmcblk0boot1 179:64 0 4M 1 disk
</pre>

=== Control PWM Fan ===

There is one 3-pin PWM Fan header on ROCK 3A/3B.

To control it, try the following steps.

* Step 1: Add rk3568-pwm8-m0-fan overlay

You need to add the item "rk3568-pwm8-m0-fan" to line "overlays=" in file /boot/uEnv.txt.
For example.

root@rock-3a:~# cat /boot/uEnv.txt | grep overlays=
overlays=rk3568-can1-m0 '''rk3568-pwm8-m0-fan'''

* Step 2: Reboot ROCK 3A/3B and confirm that the directory '''/sys/devices/platform/fe6f0000.pwm''' related to pwm8 is created.

root@rock-3a:~# ls /sys/devices/platform/fe6f0000.pwm
driver driver_override modalias of_node power pwm subsystem uevent

* Step 3: Set PWM period, duty_cycle, polarity and enable with '''root permission'''.

root@rock-3a:~# echo 0 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/export
root@rock-3a:~# echo 10000 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/period
root@rock-3a:~# echo 5000 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/duty_cycle
root@rock-3a:~# echo normal > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/polarity
root@rock-3a:~# echo 1 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/enable # Turn on fan
root@rock-3a:~# echo 0 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/enable # Turn off fan

== Work with ROCK 3 Ubuntu ==

=== Introduction to ROCK 3 Ubuntu ===

This guide is available for official ROCK 3 (ROCK 3 A, Radxa CM3, etc) Ubuntu images.

ROCK 3 Ubuntu server is an easy to use system. While working with ROCK 3 Ubuntu Server, you will find it do well on playing music, Internet, Bluetooth, AI and so on.

ROCK 3 Ubuntu server uses '''systemd''' to manage system.

Command prepended by $ means the command may be executed by an unprivileged user. And command prepended by # means the command may be executed by an privileged user. But the symbol, $ or #, is not part of the command.

=== List of boards supported ===

* ROCK 3A
* ROCK 3B
* Radxa E23
* Radxa E25
* Radxa CM3 IO

=== Access from the Host PC/Laptop ===

==== Option 1: Serial console ====

Check [[rock3/dev/serial-console | Serial Console]]

==== Option 2: SSH ====
SSH server is enabled on port 22 of ROCK 3 default image.

Please use [https://angryip.org/ angryip] to find your board IP address.

$ ping ip-of-device
$ ssh rock@ip-of-device

=== Ubuntu Default User Account ===

=== Radxa APT ===

Radxa APT source includes stable one and testing one. Stable source includes stable packages while testing source includes latest but maybe unstable packages.

Radxa APT stable source is added by default while testing source is not added.

You can uncomment line like "deb http://apt.radxa.com/focal-testing/ focal main" in file /etc/apt/sources.list.d/apt-radxa-com.list to add testing source.

See file /etc/apt/sources.list.d/apt-radxa-com.list

deb http://apt.radxa.com/focal-stable/ focal main
deb http://apt.radxa.com/focal-testing/ focal main

After adding testing source, you need to update APT and install your needed packages.

$ sudo apt-get update

For more detail about Radxa APT, please see [[rock3/radxa-apt | Radxa APT]].

=== Upgrade necessary packages ===

$ sudo apt-get update
$ sudo apt-get install -y rockchip-overlay
$ sudo apt-get install -y linux-4.19-rock-3-latest

=== Check DDR size ===

ROCK 3 comes in several different DDR sizes, such as 1G, 2G, 4G, 8G, etc.
Here shows 8GB RAM on ROCK 3A.

root@rock-3a:~# free -h
total used free shared buff/cache available
Mem: '''7.4Gi''' 72Mi 7.1Gi 16Mi 182Mi 7.2Gi

=== Test RTC Device ===

ROCK 3A is equipped with one RTC IC hym8563.

Firstly, plug in [[rock3/hardware/rtc | RTC battery]] to give power to RTC IC. Please note that we should keep the RTC battery in the RTC connector.

Plug in power adaper to power on ROCK 3A.

And confirm that the rtc hym8563 device is created.

root@rock3a:~# dmesg | grep rtc
[ 1.128345] rk808-rtc rk808-rtc: registered as rtc0
[ 1.130163] rk808-rtc rk808-rtc: setting system clock to 2017-08-04 09:00:05 UTC (1501837205)
[ 2.801453] rtc-hym8563 5-0051: rtc core: registered hym8563 as rtc1

Secondly, use the following commands to set the system time and synchronize it to rtc1.

root@rock3a:~# date -s "2021-08-17 20:00:00"
root@rock3a:~# hwclock -w -f /dev/rtc1
root@rock3a:~# hwclock -r -f /dev/rtc1
2021-08-17 20:00:04.745124+00:00
root@rock3a:~# poweroff

and then remove the power adapter.

Finally, 10 minutes later we power on ROCK 3A via Type-C Port and check the rtc clock.

root@rock3a:~# hwclock -r -f /dev/rtc1
2021-08-17 20:10:14.745124+00:00

We see that rtc runs about 10 minutes also. That's good.

===Test Audio Player===

*Download a wav audio file, and use the command to test the HP player.

$ amixer -c 1 cset numid=1 3
numid=1,iface=MIXER,name='Playback Path'
; type=ENUMERATED,access=rw------,values=1,items=11
; Item #0 'OFF'
; Item #1 'RCV'
; Item #2 'SPK'
; Item #3 'HP'
; Item #4 'HP_NO_MIC'
; Item #5 'BT'
; Item #6 'SPK_HP'
; Item #7 'RING_SPK'
; Item #8 'RING_HP'
; Item #9 'RING_HP_NO_MIC'
; Item #10 'RING_SPK_HP'
: values=3

$ aplay -D plughw:1,0 test.wav
$ Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

*To test the Mic recordding， please follow:

$ amixer -c 1 cset numid=2 1
$ arecord -Dhw:1,0 -d 10 -f cd -r 44100 -c 2 -t wav ./mic_test.wav #this is a record command
Recording WAVE './mic_test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
$ aplay -D plughw:1,0 mic_test.wav

=== Test USB Host Ports ===

There are two USB 2.0 host ports and two USB 3.0 host ports.

Plug in U Disk and fire command ''lsblk''. Here /dev/sda is related to U Disk.

<pre>
root@rock-3a:~# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 1 14.4G 0 disk
|-sda1 8:1 1 200M 0 part
`-sda2 8:2 1 14.2G 0 part
mmcblk0 179:0 0 14.5G 0 disk

mmcblk0boot0 179:32 0 4M 1 disk
mmcblk0boot1 179:64 0 4M 1 disk
</pre>

Mount U Disk.

<pre>
root@rock-3a:~# mount /dev/sda2 /mnt/
</pre>

Confirm that U Disk is mounted.

<pre>
root@rock-3a:~# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 1 14.4G 0 disk
|-sda1 8:1 1 200M 0 part

mmcblk0boot1 179:64 0 4M 1 disk
</pre>

=== Control PWM Fan ===

There is one 3-pin PWM Fan header on ROCK 3A/3B.

To control it, try the following steps.

* Step 1: Add rk3568-pwm8-m0-fan overlay

You need to add the item "rk3568-pwm8-m0-fan" to line "overlays=" in file /boot/uEnv.txt.
For example.

root@rock-3a:~# cat /boot/uEnv.txt | grep overlays=
overlays=rk3568-can1-m0 '''rk3568-pwm8-m0-fan'''

* Step 2: Reboot ROCK 3A/3B and confirm that the directory '''/sys/devices/platform/fe6f0000.pwm''' related to pwm8 is created.

root@rock-3a:~# ls /sys/devices/platform/fe6f0000.pwm
driver driver_override modalias of_node power pwm subsystem uevent

* Step 3: Set PWM period, duty_cycle, polarity and enable with '''root permission'''.

root@rock-3a:~# echo 0 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/export
root@rock-3a:~# echo 10000 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/period
root@rock-3a:~# echo 5000 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/duty_cycle
root@rock-3a:~# echo normal > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/polarity
root@rock-3a:~# echo 1 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/enable # Turn on fan
root@rock-3a:~# echo 0 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/enable # Turn off fan

== Work with ROCK 3 Ubuntu ==

=== Introduction to ROCK 3 Ubuntu ===

This guide is available for official ROCK 3 (ROCK 3 A, Radxa CM3, etc) Ubuntu images.

ROCK 3 Ubuntu server is an easy to use system. While working with ROCK 3 Ubuntu Server, you will find it do well on playing music, Internet, Bluetooth, AI and so on.

ROCK 3 Ubuntu server uses '''systemd''' to manage system.

Command prepended by $ means the command may be executed by an unprivileged user. And command prepended by # means the command may be executed by an privileged user. But the symbol, $ or #, is not part of the command.

=== List of boards supported ===

* ROCK 3A
* ROCK 3B
* Radxa E23
* Radxa E25
* Radxa CM3 IO

=== Access from the Host PC/Laptop ===

==== Option 1: Serial console ====

Check [[rock3/dev/serial-console | Serial Console]]

==== Option 2: SSH ====
SSH server is enabled on port 22 of ROCK 3 default image.

Please use [https://angryip.org/ angryip] to find your board IP address.

$ ping ip-of-device
$ ssh rock@ip-of-device

=== Ubuntu Default User Account ===

Non-root User:

User Name : rock
Password : rock

=== Radxa APT ===

Radxa APT source includes stable one and testing one. Stable source includes stable packages while testing source includes latest but maybe unstable packages.

Radxa APT stable source is added by default while testing source is not added.

You can uncomment line like "deb http://apt.radxa.com/focal-testing/ focal main" in file /etc/apt/sources.list.d/apt-radxa-com.list to add testing source.

See file /etc/apt/sources.list.d/apt-radxa-com.list

deb http://apt.radxa.com/focal-stable/ focal main
deb http://apt.radxa.com/focal-testing/ focal main

After adding testing source, you need to update APT and install your needed packages.

$ sudo apt-get update

For more detail about Radxa APT, please see [[rock3/radxa-apt | Radxa APT]].

=== Upgrade necessary packages ===

$ sudo apt-get update
$ sudo apt-get install -y rockchip-overlay
$ sudo apt-get install -y linux-4.19-rock-3-latest

=== Check DDR size ===

ROCK 3 comes in several different DDR sizes, such as 1G, 2G, 4G, 8G, etc.
Here shows 8GB RAM on ROCK 3A.

root@rock-3a:~# free -h
total used free shared buff/cache available
Mem: '''7.4Gi''' 72Mi 7.1Gi 16Mi 182Mi 7.2Gi

=== Test RTC Device ===

Firstly, plug in RTC battery and power on.Check the rtc device:

root@rock3a:~# dmesg | grep rtc
[ 1.128345] rk808-rtc rk808-rtc: registered as rtc0
[ 1.130163] rk808-rtc rk808-rtc: setting system clock to 2017-08-04 09:00:05 UTC (1501837205)
[ 2.801453] rtc-hym8563 5-0051: rtc core: registered hym8563 as rtc1

Secondly, use the following commands to set the system time and synchronize it to rtc1.

root@rock3a:~# date -s "2021-08-17 20:00:00"
root@rock3a:~# hwclock -w -f /dev/rtc1
root@rock3a:~# hwclock -r -f /dev/rtc1
2021-08-17 20:00:04.745124+00:00
root@rock3a:~# poweroff

and then disconnect the power supply

Finally, 10 minutes later we power on ROCK 3 A via Type-C Port and check the rtc clock.

root@rock3a:~# hwclock -r -f /dev/rtc1
2021-08-17 20:10:14.745124+00:00

We see that rtc runs about 10 minutes also. That's good.

===Test Audio Player===

*Download a wav audio file, and use the command to test the HP player.

$ amixer -c 1 cset numid=1 3
numid=1,iface=MIXER,name='Playback Path'
; type=ENUMERATED,access=rw------,values=1,items=11
; Item #0 'OFF'
; Item #1 'RCV'
; Item #2 'SPK'
; Item #3 'HP'
; Item #4 'HP_NO_MIC'
; Item #5 'BT'
; Item #6 'SPK_HP'
; Item #7 'RING_SPK'
; Item #8 'RING_HP'
; Item #9 'RING_HP_NO_MIC'
; Item #10 'RING_SPK_HP'
: values=3

$ aplay -D plughw:1,0 test.wav
$ Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

*To test the Mic recordding， please follow:

$ amixer -c 1 cset numid=2 1
$ arecord -Dhw:1,0 -d 10 -f cd -r 44100 -c 2 -t wav ./mic_test.wav #this is a record command
Recording WAVE './mic_test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
$ aplay -D plughw:1,0 mic_test.wav

=== Test USB Host Ports ===

There are two USB 2.0 host ports and two USB 3.0 host ports.

Plug in U Disk and fire command ''lsblk''. Here /dev/sda is related to U Disk.

<pre>
root@rock-3a:~# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 1 14.4G 0 disk
|-sda1 8:1 1 200M 0 part
`-sda2 8:2 1 14.2G 0 part
mmcblk0 179:0 0 14.5G 0 disk
|-mmcblk0p1 179:1 0 512M 0 part /boot
`-mmcblk0p2 179:2 0 14G 0 part /
mmcblk0boot0 179:32 0 4M 1 disk
mmcblk0boot1 179:64 0 4M 1 disk
</pre>

Mount U Disk.

<pre>
root@rock-3a:~# mount /dev/sda2 /mnt/
</pre>

Confirm that U Disk is mounted.

<pre>
root@rock-3a:~# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 1 14.4G 0 disk
|-sda1 8:1 1 200M 0 part
`-sda2 8:2 1 14.2G 0 part /mnt

mmcblk0boot0 179:32 0 4M 1 disk
mmcblk0boot1 179:64 0 4M 1 disk
</pre>

=== Control PWM Fan ===

There is one 3-pin PWM Fan header on ROCK 3A/3B.

To control it, try the following steps.

* Step 1: Add rk3568-pwm8-m0-fan overlay

You need to add the item "rk3568-pwm8-m0-fan" to line "overlays=" in file /boot/uEnv.txt.
For example.

root@rock-3a:~# cat /boot/uEnv.txt | grep overlays=
overlays=rk3568-can1-m0 '''rk3568-pwm8-m0-fan'''

* Step 2: Reboot ROCK 3A/3B and confirm that the directory '''/sys/devices/platform/fe6f0000.pwm''' related to pwm8 is created.

root@rock-3a:~# ls /sys/devices/platform/fe6f0000.pwm
driver driver_override modalias of_node power pwm subsystem uevent

* Step 3: Set PWM period, duty_cycle, polarity and enable with '''root permission'''.

root@rock-3a:~# echo 0 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/export
root@rock-3a:~# echo 10000 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/period
root@rock-3a:~# echo 5000 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/duty_cycle
root@rock-3a:~# echo normal > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/polarity
root@rock-3a:~# echo 1 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/enable # Turn on fan
root@rock-3a:~# echo 0 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/enable # Turn off fan

=== Radxa APT ===

Radxa APT source includes stable one and testing one. Stable source includes stable packages while testing source includes latest but maybe unstable packages.

Radxa APT stable source is added by default while testing source is not added.

You can uncomment line like "deb http://apt.radxa.com/buster-testing/ buster main" in file /etc/apt/sources.list.d/apt-radxa-com.list to add testing source.

See file /etc/apt/sources.list.d/apt-radxa-com.list

deb http://apt.radxa.com/buster-stable/ buster main
deb http://apt.radxa.com/buster-testing/ buster main

After adding testing source, you need to update APT and install your needed packages.

$ sudo apt-get update

For more detail about Radxa APT, please see [[rock3/radxa-apt | Radxa APT]].

=== Upgrade necessary packages ===

Here is the example of upgrading rockchip-overlay and kernel packages.
Pakcage linux-4.19-rock-3-latest provides the latest ROCK 3 kernel packages.

$ sudo apt-get update
$ sudo apt-get install -y rockchip-overlay
$ sudo apt-get install -y linux-4.19-rock-3-latest

=== Check DDR size ===

ROCK 3 comes in several different DDR sizes, such as 1G, 2G, 4G, 8G, etc.

* ROCK 3A has one 40-pin expansion header. To control them, see [[rock3/hardware/rock3a-gpio | ROCK 3A GPIO ]].

=== <span id="common_hardware_interface">Common Hardware Interfaces, I2C, PWM, SPI, UART, CAN, etc</span> ===

The ROCK 3 system images use configuration file /boot/uEnv.txt.

'''Warning: Remember there is only one line including item "overlays=" in file /boot/uEnv.txt.'''

To enable I2C, PWM, SPI, UART, CAN, etc, please see '''RK3566/RK3568 Available Overlay (ROCK 3A, ROCK 3B, Radxa CM3)''' part of [[rock3/Debian/device-tree-overlays | Device Tree Overlays]]

=== Test RTC Device ===

Firstly, plug in RTC battery and power on.Check the rtc device:

root@rock3a:~# dmesg | grep rtc
[ 1.128345] rk808-rtc rk808-rtc: registered as rtc0
[ 1.130163] rk808-rtc rk808-rtc: setting system clock to 2017-08-04 09:00:05 UTC (1501837205)
[ 2.801453] rtc-hym8563 5-0051: rtc core: registered hym8563 as rtc1

Secondly, use the following commands to set the system time and synchronize it to rtc1.

root@rock3a:~# date -s "2021-08-17 20:00:00"
root@rock3a:~# hwclock -w -f /dev/rtc1
root@rock3a:~# hwclock -r -f /dev/rtc1
2021-08-17 20:00:04.745124+00:00
root@rock3a:~# poweroff

and then disconnect the power supply

Finally, 10 minutes later we power on ROCK 3 A via Type-C Port and check the rtc clock.

root@rock3a:~# hwclock -r -f /dev/rtc1
2021-08-17 20:10:14.745124+00:00

We see that rtc runs about 10 minutes also. That's good.

=== Test Audio Player===

Download a wav audio file, and use the command to test the HP player.

$ amixer -c 1 cset numid=1 3
numid=1,iface=MIXER,name='Playback Path'
; type=ENUMERATED,access=rw------,values=1,items=11
; Item #0 'OFF'
; Item #1 'RCV'
; Item #2 'SPK'
; Item #3 'HP'
; Item #4 'HP_NO_MIC'
; Item #5 'BT'
; Item #6 'SPK_HP'
; Item #7 'RING_SPK'
; Item #8 'RING_HP'
; Item #9 'RING_HP_NO_MIC'
; Item #10 'RING_SPK_HP'
: values=3

$ aplay -D plughw:1,0 test.wav
Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

To test the Mic recording, please follow：
$ amixer -c 1 cset numid=2 1
$ arecord -Dhw:1,0 -d 10 -f cd -r 44100 -c 2 -t wav ./mic_test.wav #this is a record command
Recording WAVE './mic_test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
$ aplay -D plughw:1,0 mic_test.wav

=== Test USB Host Ports ===

There are two USB 2.0 host ports and two USB 3.0 host ports.

Plug in U Disk and fire command ''lsblk''. Here /dev/sda is related to U Disk.

<pre>
root@rock-3a:~# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 1 14.4G 0 disk
|-sda1 8:1 1 200M 0 part
`-sda2 8:2 1 14.2G 0 part

mmcblk0boot1 179:64 0 4M 1 disk
</pre>

Mount U Disk.

<pre>
root@rock-3a:~# mount /dev/sda2 /mnt/
</pre>

Confirm that U Disk is mounted.

<pre>
root@rock-3a:~# lsblk

mmcblk0boot1 179:64 0 4M 1 disk
</pre>

=== Control PWM Fan ===

There is one 3-pin PWM Fan header on ROCK 3A/3B.

To control it, try the following steps.

* Step 1: Add rk3568-pwm8-m0-fan overlay

You need to add the item "rk3568-pwm8-m0-fan" to line "overlays=" in file /boot/uEnv.txt.
For example.

root@rock-3a:~# cat /boot/uEnv.txt | grep overlays=
overlays=rk3568-can1-m0 '''rk3568-pwm8-m0-fan'''

* Step 2: Reboot ROCK 3A/3B and confirm that the directory '''/sys/devices/platform/fe6f0000.pwm''' related to pwm8 is created.

root@rock-3a:~# ls /sys/devices/platform/fe6f0000.pwm
driver driver_override modalias of_node power pwm subsystem uevent

* Step 3: Set PWM period, duty_cycle, polarity and enable with '''root permission'''.

root@rock-3a:~# echo 0 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/export
root@rock-3a:~# echo 10000 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/period
root@rock-3a:~# echo 5000 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/duty_cycle
root@rock-3a:~# echo normal > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/polarity
root@rock-3a:~# echo 1 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/enable # Turn on fan
root@rock-3a:~# echo 0 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/enable # Turn off fan

=== Libmraa on ROCK 3A ===

This guide describes how to use libmraa on ROCK 3 to access GPIO, SPI, and other peripherals.

=== Requirement ===
* ROCK 3A
* You need our latest [https://github.com/radxa/rock-3-images-released/releases official image]

=== Install essential packages ===
Prebuilt libmraa is located in our Radxa APT Focal and Buster repositories.

Update your <code>/etc/apt/sources.list.d/apt-radxa-com.list</code> accordingly to enable Radxa APT repository.

* '''For Debian Buster'''
deb http://apt.radxa.com/buster-stable/ buster main
deb http://apt.radxa.com/buster-testing/ buster main
* '''For Ubuntu Focal'''
deb http://apt.radxa.com/focal-stable/ focal main
deb http://apt.radxa.com/focal-testing/ focal main

Update and install libmraa
sudo apt-get update
sudo apt-get install libmraa

==== Enable interface ====

See ROCK 3A [[rock3/hardware/gpio | GPIO pintout]]. ROCK 3A has a 40 pins colorful expansion header. Each pin is distinguished by color. mraa define is shown below:

PIN13 PWM'''15'''_M0
PIN19 PWM'''15'''_M1

1 ADC:
PIN37 ADC_IN5 //the measure voltage must lower than 1.8v

Since many peripherals are reusing the same physical pin, all but one has to be disabled to allow proper functionality. While in a normal PC user can easily disable or enable peripherals in their UEFI firmware, currently there is no such universal equivalent in ARM world. Instead, Device tree blobs (dtb) and Device tree overlays (dtbo) are used to inform Linux kernel the existence of external devices. Please refer to [[Device-tree-overlays#Part_One:_Rockchip | this guide]] on available dtbo for ROCK 3A. Please read those carefully or you may get an unbootable system.

==== Run libmraa tests ====

After set correct dtbo to use, reboot Radxa Zero for change to take effect. You can now try some examples supplied by libmraa. They can be used to test SPI, UART, I2C, GPIO, and so on.

In this example, we will use the sample files located under /usr/local/share/mraa/examples/c.

And we copy them to home directory.

rock@rock3a:~/mraa-examples$ sudo cp -av /usr/local/share/mraa/examples/c /home/rock/mraa-examples

You should pay more attention to the Black Bold words when modifying configuration file /boot/uEnv.txt.

===== GPIO test =====

root@rock3a:~# mraa-gpio set 40 0 #pin40 pull low

===== I2C test =====
ROCK 3A V1.3 provides 3 I2C,There are I2C1 , I2C2m0, I2C3m0.
If you need the I2C function, you can turn on one or more of them.

Firstly, modify the /boot/uEnv.txt file to add the following

root@rock3a:~# cat /boot/uEnv.txt
verbosity=7
overlay_prefix=rockchip
rootfstype=ext4
fdtfile=rockchip/rk3568-rock-3-a.dtb
overlays=rk3568-pwm8-m0-fan '''rk3568-i2c3-m0'''
rootuuid=ee2ce23a-e0b1-4625-a54b-6ce12c167e97
initrdsize=0x81bfa9
kernelversion=4.19.193-16-rockchip-g0cca7bdf9cdb
initrdimg=initrd.img-4.19.193-16-rockchip-g0cca7bdf9cdb
kernelimg=vmlinuz-4.19.193-16-rockchip-g0cca7bdf9cdb

Then, use mraa-i2c tool to test,we must have a i2c slave device,for example:
root@rock3a:~# mraa-i2c list
Bus 0: id=01 type=linux default
Bus 1: id=02 type=linux
Bus 2: id=03 type=linux

root@rock3a:~# mraa-i2c detect 2
00: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- 68 -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

We use MPU6050 tets i2c.
Modify the macro MPU6050 in '''/home/rock/mraa-examples/i2c_mpu6050.c''' ,as follows to test I2C3m0.

/* mraa header */
#include "mraa/i2c.h"
'''#define I2C_BUS 2'''

rock@rock3a:~/mraa-examples$ gcc -o i2c_mpu6050 i2c_mpu6050.c -lmraa
rock@rock3a:~/mraa-examples$ sudo ./i2c_mpu6050

accel: x:0 y:0 z:0
gyro: x:6 y:136 z:-50

accel: x:0 y:0 z:0
gyro: x:-5 y:48 z:-103

===== UART test =====
ROCK 3A V1.3 provides 6 UART,There are '''uart0''' ,'''uart3''', '''uart5''', '''uart7''', '''uart8''', '''uart9'''.
If you need the uart function, you can turn on one or more of them.

Firstly, Disable console and enable '''uart0''' for uart test.modify the '''/boot/uEnv.txt''' file to add the following

root@rock3a:~# cat /boot/uEnv.txt
verbosity=7
overlay_prefix=rockchip
rootfstype=ext4
fdtfile=rockchip/rk3568-rock-3-a.dtb
overlays=rk3568-pwm8-m0-fan '''rk3568-uart0'''
rootuuid=ee2ce23a-e0b1-4625-a54b-6ce12c167e97
initrdsize=0x81bfa9
kernelversion=4.19.193-16-rockchip-g0cca7bdf9cdb
initrdimg=initrd.img-4.19.193-16-rockchip-g0cca7bdf9cdb
kernelimg=vmlinuz-4.19.193-16-rockchip-g0cca7bdf9cdb

Here set console to NULL value.

then reboot . use '''ssh''' connect to rock3a in a new window, to send data.

send command follow:
rock@rock3a:~$ sudo mraa-uart '''dev 0''' baud 1500000 send radxa
rock@rock3a:~$ sudo mraa-uart '''dev 0''' baud 1500000 send radxa

Another window sets the baud 1500000 and receives the data by serial console
radxaradxa

===== SPI test =====

Change overlays in /boot/uEnv.txt and reboot

root@rock3a:~# cat /boot/uEnv.txt
verbosity=7
overlay_prefix=rockchip
rootfstype=ext4
fdtfile=rockchip/rk3568-rock-3-a.dtb
overlays=rk3568-pwm8-m0-fan rk3568-spi3-m1-cs0-spidev
rootuuid=ee2ce23a-e0b1-4625-a54b-6ce12c167e97
initrdsize=0x81bfa9
kernelversion=4.19.193-16-rockchip-g0cca7bdf9cdb
initrdimg=initrd.img-4.19.193-16-rockchip-g0cca7bdf9cdb
kernelimg=vmlinuz-4.19.193-16-rockchip-g0cca7bdf9cdb

then execute command, sync, followed by '''reboot'''.

Create file test-spi.c and add the following contents.

rock@rock3a:~/mraa-examples$ cat test-spi.c
#include <signal.h>
#include <stdlib.h>
#include <unistd.h>

/* mraa header */
#include "mraa/spi.h"

/* SPI declaration */
'''#define SPI_BUS 3'''

/* SPI frequency in Hz */
#define SPI_FREQ 10000000
int
main(int argc, char** argv)
{
mraa_result_t status = MRAA_SUCCESS;
mraa_spi_context spi;
int i, j;

/* initialize mraa for the platform (not needed most of the times) */
mraa_init();

//! [Interesting]
/* initialize SPI bus */
spi = mraa_spi_init(SPI_BUS);
if (spi == NULL) {
fprintf(stderr, "Failed to initialize SPI\n");
mraa_deinit();
return EXIT_FAILURE;
}

/* set SPI frequency */
status = mraa_spi_frequency(spi, SPI_FREQ);
if (status != MRAA_SUCCESS)
goto err_exit;

/* set big endian mode */
status = mraa_spi_lsbmode(spi, 0);
if (status != MRAA_SUCCESS) {
goto err_exit;
}

j = 10;
while(j) {
j--;
printf("0x%x\n",mraa_spi_write(spi, 0xaa));
}
err_exit:
mraa_result_print(status);

/* stop spi */
mraa_spi_stop(spi);

/* deinitialize mraa for the platform (not needed most of the times) */
mraa_deinit();

return EXIT_FAILURE;
}
rock@rock3a:~/mraa-examples$ gcc -o test-spi test-spi.c -lmraa

Then short pin19 and pin21 and run test-spi

rock@rock3a:~/mraa-examples$ sudo ./test-spi
0xaa
0xaa
0xaa
0xaa
0xaa
0xaa
0xaa
0xaa
0xaa
0xaa
MRAA: SUCCESS

===== PWM test =====

ROCK 3A V1.3 provides 7 PWM, there are '''pwm1-m0''', '''pwm1-m1''', '''pwm2-m0''', '''pwm2-m1''', '''pwm9-m0''', '''pwm12-m1''', '''pwm13-m1''', '''pwm14-m0''', '''pwm14-m1''', '''pwm15-m0''', '''pwm15-m1'''.

'''but only one PWM function can be used at a time currently'''.

Firstly, modify the /boot/uEnv.txt file to add the following

root@rock3a:~# cat /boot/uEnv.txt
verbosity=7
overlay_prefix=rockchip
rootfstype=ext4
fdtfile=rockchip/rk3568-rock-3-a.dtb
overlays=rk3568-pwm8-m0-fan '''rk3568-pwm1-m0''' #rk3568-pwm8-m0-fan should be here to use pwm fan.
rootuuid=ee2ce23a-e0b1-4625-a54b-6ce12c167e97
initrdsize=0x81bfa9
kernelversion=4.19.193-16-rockchip-g0cca7bdf9cdb

==== More details about 40-pin Header ====
* Function marked with color orange is the default function of this pin.
* Except Pins for power supply, all pins are laid out directly to Soc RK3399.
* For pin 3, 5, 27, 28, 29 and 31, each pin is connected to the 3.0V supply through a 4.7K pull-up resistor.
* Pin 19, 21, 23, 24 are laid out directly to the pins of SPI device on board.
* Pin 7 is laid out directly to the pin of MIPI CSI on board.
* UART
** UART2 is enabled as U-boot and Linux serial console by default. Check [[Rockpi4/dev/serial-console]] to use. Check [[Rockpi4/hardware/devtree_overlays]] to disable serial console on UART2.
** UART2 & UART4 support a wide range of baud rate. It includes but not is not limited to the following baud rates. For instance, 115200bps. 500000bps, 1500000bps and so on.
** For v1.4 and later hardware, on board SPI flash is soldered, UART4 PINs are used as SPI function.
* For I2C-2 and I2C-7
** We have do the test using the i2c device e2prom. We need to open the i2c device file, and then do the read or write operation.

=== IO Voltage ===
RK3399 have three IO voltages, 1.8V/3.0V/3.3V. For ROCK Pi 4, below is the default voltage:

<pre>
| GPIO | Voltage Level | Tolerance |
| ---------- | ------------- | --------- |
| GPIO3_C0 | 3.3V | 3.465V |
| ADC_IN0 | 1.8V | 1.98V |
| Other GPIO | 3.0V | 3.14V |

</pre>

=== GPIO number ===
Rockchip RK3399 GPIO has 5 banks, GPIO0 to GPIO4, each bank has 32pins, naming as below:

GPIO0_A0 ~ A7
GPIO0_B0 ~ B7
GPIO0_C0 ~ C7
GPIO0_D0 ~ D7

GPIO1_A0 ~ A7
....
GPIO1_D0 ~ D7

For Rockchip 4.4 kernel, the GPIO number can be calculated as below, take GPIO4_D5 (PIN22 on 40PIN GPIO) as an example:

GPIO4_D5 = 4*32 + 3*8 + 5 = 157
(A=0, B=1, C=2, D=3)

[[File:Gpio_number.png]]

To set GPIO4_D5 output

cd /sys/class/gpio
echo 157 > export
cd gpio157
echo out > direction
echo 1 > value # output high
echo 0 > value # output low

* For pin 3, 5, 27, 28, 29 and 31, each pin is connected to the 3.0V supply through a 4.7K pull-up resistor.
* Pin 19, 21, 23, 24 are laid out directly to the pins of SPI device on board.
* Pin 7 is laid out directly to the pin of MIPI CSI on board.
* UART
** UART2 is enabled as U-boot and Linux serial console by default. Check [[Rockpi4/dev/serial-console]] to use. Check [[Rockpi4/hardware/devtree_overlays]] to disable serial console on UART2.
** UART2 & UART4 support a wide range of baud rate. It includes but not is not limited to the following baud rates. For instance, 115200bps. 500000bps, 1500000bps and so on.
** For v1.4 and later hardware, on board SPI flash is soldered, UART4 PINs are used as SPI function.
* For I2C-2 and I2C-7
** We have do the test using the i2c device e2prom. We need to open the i2c device file, and then do the read or write operation.

=== IO Voltage ===
RK3399 have three IO voltages, 1.8V/3.0V/3.3V. For ROCK Pi 4, below is the default voltage:

<pre>
| GPIO | Voltage Level | Tolerance |
| ---------- | ------------- | --------- |
| GPIO3_C0 | 3.3V | 3.465V |
| ADC_IN0 | 1.8V | 1.98V |
| Other GPIO | 3.0V | 3.14V |

</pre>

=== GPIO number ===
Rockchip RK3399 GPIO has 5 banks, GPIO0 to GPIO4, each bank has 32pins, naming as below:

GPIO0_A0 ~ A7
GPIO0_B0 ~ B7
GPIO0_C0 ~ C7
GPIO0_D0 ~ D7

GPIO1_A0 ~ A7
....
GPIO1_D0 ~ D7

For Rockchip 4.4 kernel, the GPIO number can be calculated as below, take GPIO4_D5 (PIN22 on 40PIN GPIO) as an example:

GPIO4_D5 = 4*32 + 3*8 + 5 = 157
(A=0, B=1, C=2, D=3)

[[File:Gpio_number.png]]

To set GPIO4_D5 output

cd /sys/class/gpio
echo 157 > export
cd gpio157
echo out > direction
echo 1 > value # output high
echo 0 > value # output low

Since many peripherals are reusing the same physical pin, all but one has to be disabled to allow proper functionality. While in a normal PC user can easily disable or enable peripherals in their UEFI firmware, currently there is no such universal equivalent in ARM world. Instead, Device tree blobs (dtb) and Device tree overlays (dtbo) are used to inform Linux kernel the existence of external devices. Please refer to [[Device-tree-overlays#Part_One:_Rockchip | this guide]] on available dtbo for ROCK 3A. Please read those carefully or you may get an unbootable system.

==== Run libmraa tests ====

After set correct dtbo to use, reboot Radxa Zero for change to take effect. You can now try some examples supplied by libmraa. They can be used to test SPI, UART, I2C, GPIO, and so on.

In this example, we will use the sample files located under /usr/local/share/mraa/examples/c.

And we copy them to home directory.

rock@rock3a:~/mraa-examples$ sudo cp -av /usr/local/share/mraa/examples/c /home/rock/mraa-examples

You should pay more attention to the Black Bold words when modifying configuration file /boot/uEnv.txt.

===== GPIO test =====

Use '''mraa-gpio tool''' to test

rock@rock3a:~$ mraa-gpio list

root@rock3a:~$ mraa-gpio set 40 1 #pin40 pull high
root@rock3a:~# mraa-gpio set 40 0 #pin40 pull low

===== I2C test =====
ROCK 3A V1.3 provides 3 I2C,There are I2C1 , I2C2m0, I2C3m0.
If you need the I2C function, you can turn on one or more of them.

Firstly, modify the /boot/uEnv.txt file to add the following

root@rock3a:~# cat /boot/uEnv.txt
verbosity=7
overlay_prefix=rockchip
rootfstype=ext4
fdtfile=rockchip/rk3568-rock-3-a.dtb
overlays=rk3568-pwm8-m0-fan '''rk3568-i2c3-m0'''
rootuuid=ee2ce23a-e0b1-4625-a54b-6ce12c167e97
initrdsize=0x81bfa9
kernelversion=4.19.193-16-rockchip-g0cca7bdf9cdb
initrdimg=initrd.img-4.19.193-16-rockchip-g0cca7bdf9cdb
kernelimg=vmlinuz-4.19.193-16-rockchip-g0cca7bdf9cdb

Then, use mraa-i2c tool to test,we must have a i2c slave device,for example:
root@rock3a:~# mraa-i2c list
Bus 0: id=01 type=linux default
Bus 1: id=02 type=linux
Bus 2: id=03 type=linux

root@rock3a:~# mraa-i2c detect 2
00: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- 68 -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

We use MPU6050 tets i2c.
Modify the macro MPU6050 in '''/home/rock/mraa-examples/i2c_mpu6050.c''' ,as follows to test I2C3m0.

/* mraa header */
#include "mraa/i2c.h"
'''#define I2C_BUS 2'''

rock@rock3a:~/mraa-examples$ gcc -o i2c_mpu6050 i2c_mpu6050.c -lmraa
rock@rock3a:~/mraa-examples$ sudo ./i2c_mpu6050
accel: x:0 y:0 z:0
gyro: x:-10 y:1 z:7

accel: x:0 y:0 z:0
gyro: x:107 y:-12 z:69

accel: x:0 y:0 z:0
gyro: x:6 y:136 z:-50

accel: x:0 y:0 z:0
gyro: x:-5 y:48 z:-103

===== UART test =====
ROCK 3A V1.3 provides 6 UART,There are '''uart0''' ,'''uart3''', '''uart5''', '''uart7''', '''uart8''', '''uart9'''.
If you need the uart function, you can turn on one or more of them.

Firstly, Disable console and enable '''uart0''' for uart test.modify the '''/boot/uEnv.txt''' file to add the following

root@rock3a:~# cat /boot/uEnv.txt
verbosity=7
overlay_prefix=rockchip
rootfstype=ext4
fdtfile=rockchip/rk3568-rock-3-a.dtb
overlays=rk3568-pwm8-m0-fan '''rk3568-uart0'''
rootuuid=ee2ce23a-e0b1-4625-a54b-6ce12c167e97
initrdsize=0x81bfa9
kernelversion=4.19.193-16-rockchip-g0cca7bdf9cdb
initrdimg=initrd.img-4.19.193-16-rockchip-g0cca7bdf9cdb
kernelimg=vmlinuz-4.19.193-16-rockchip-g0cca7bdf9cdb

Here set console to NULL value.

then reboot . use '''ssh''' connect to rock3a in a new window, to send data.

send command follow:
rock@rock3a:~$ sudo mraa-uart '''dev 0''' baud 1500000 send radxa
rock@rock3a:~$ sudo mraa-uart '''dev 0''' baud 1500000 send radxa

Another window sets the baud 1500000 and receives the data by serial console
radxaradxa

===== SPI test =====

Change overlays in /boot/uEnv.txt and reboot

root@rock3a:~# cat /boot/uEnv.txt
verbosity=7
overlay_prefix=rockchip
rootfstype=ext4
fdtfile=rockchip/rk3568-rock-3-a.dtb
overlays=rk3568-pwm8-m0-fan rk3568-spi3-m1-cs0-spidev
rootuuid=ee2ce23a-e0b1-4625-a54b-6ce12c167e97
initrdsize=0x81bfa9
kernelversion=4.19.193-16-rockchip-g0cca7bdf9cdb
initrdimg=initrd.img-4.19.193-16-rockchip-g0cca7bdf9cdb
kernelimg=vmlinuz-4.19.193-16-rockchip-g0cca7bdf9cdb

then execute command, sync, followed by '''reboot'''.

Create file test-spi.c and add the following contents.

rock@rock3a:~/mraa-examples$ cat test-spi.c
#include <signal.h>
#include <stdlib.h>
#include <unistd.h>

/* mraa header */
#include "mraa/spi.h"

/* SPI declaration */
'''#define SPI_BUS 3'''

/* SPI frequency in Hz */
#define SPI_FREQ 10000000
int
main(int argc, char** argv)
{
mraa_result_t status = MRAA_SUCCESS;
mraa_spi_context spi;
int i, j;

/* initialize mraa for the platform (not needed most of the times) */
mraa_init();

//! [Interesting]
/* initialize SPI bus */
spi = mraa_spi_init(SPI_BUS);
if (spi == NULL) {
fprintf(stderr, "Failed to initialize SPI\n");
mraa_deinit();
return EXIT_FAILURE;
}

/* set SPI frequency */
status = mraa_spi_frequency(spi, SPI_FREQ);
if (status != MRAA_SUCCESS)
goto err_exit;

/* set big endian mode */
status = mraa_spi_lsbmode(spi, 0);
if (status != MRAA_SUCCESS) {
goto err_exit;
}

j = 10;
while(j) {
j--;
printf("0x%x\n",mraa_spi_write(spi, 0xaa));
}
err_exit:
mraa_result_print(status);

/* stop spi */
mraa_spi_stop(spi);

/* deinitialize mraa for the platform (not needed most of the times) */
mraa_deinit();

return EXIT_FAILURE;
}
rock@rock3a:~/mraa-examples$ gcc -o test-spi test-spi.c -lmraa

Then short pin19 and pin21 and run test-spi

rock@rock3a:~/mraa-examples$ sudo ./test-spi
0xaa
0xaa
0xaa
0xaa
0xaa
0xaa
0xaa
0xaa
0xaa
0xaa
MRAA: SUCCESS

===== PWM test =====

ROCK 3A V1.3 provides 7 PWM, there are '''pwm1-m0''', '''pwm1-m1''', '''pwm2-m0''', '''pwm2-m1''', '''pwm9-m0''', '''pwm12-m1''', '''pwm13-m1''', '''pwm14-m0''', '''pwm14-m1''', '''pwm15-m0''', '''pwm15-m1'''.

'''but only one PWM function can be used at a time currently'''.

Firstly, modify the /boot/uEnv.txt file to add the following

root@rock3a:~# cat /boot/uEnv.txt
verbosity=7
overlay_prefix=rockchip
rootfstype=ext4
fdtfile=rockchip/rk3568-rock-3-a.dtb
overlays=rk3568-pwm8-m0-fan '''rk3568-pwm1-m0'''
rootuuid=ee2ce23a-e0b1-4625-a54b-6ce12c167e97
initrdsize=0x81bfa9
kernelversion=4.19.193-16-rockchip-g0cca7bdf9cdb
initrdimg=initrd.img-4.19.193-16-rockchip-g0cca7bdf9cdb
kernelimg=vmlinuz-4.19.193-16-rockchip-g0cca7bdf9cdb

Modify the macro PWM in /home/rock/mraa-examples/pwm.c as follows to test PWM1_M0.

'''/* PWM declaration */'''
'''#define PWM 15''' //15 means its pin number

Save and compile pwm.c
rock@rock3a:~/mraa-examples$ gcc -o pwm pwm.c -lmraa

PWM value is 0.040014
PWM value is 0.049984
PWM value is 0.059999

===== ADC test =====

connect signal you want to measure, and then compile mraa example c file, aio.c, to test.

rock@rock3a:~/mraa-examples$ gcc -o aio aio.c -lmraa
rock@rock3a:~/mraa-examples$ sudo ./aio
ADC A0 read 20F - 527
ADC A0 read float - 0.51808
ADC A0 read 212 - 530

When using, you need to pay attention to the pin's multiplexing function to see if there is a conflict.
==== Test ====

Package libmraa provides some examples for testing spi, uart, i2c, gpio, etc. We way use the c files in /usr/local/share/mraa/examples/c.

And we copy them to home directory.

rock@rock3a:~/mraa-examples$ sudo cp -av /usr/local/share/mraa/examples/c /home/rock/mraa-examples

You should pay more attention to the Black Bold words when modifying configuration file /boot/uEnv.txt.

===== GPIO test =====

Use '''mraa-gpio tool''' to test

rock@rock3a:~$ mraa-gpio list
01 3V3:
02 5V:
03 I2C3_SDA_M0: GPIO I2C UART

root@rock3a:~$ mraa-gpio set 40 1 #pin40 pull high
root@rock3a:~# mraa-gpio set 40 0 #pin40 pull low

===== I2C test =====
ROCK 3A V1.3 provides 3 I2C,There are I2C1 , I2C2m0, I2C3m0.
If you need the I2C function, you can turn on one or more of them.

Firstly, modify the /boot/uEnv.txt file to add the following

root@rock3a:~# cat /boot/uEnv.txt
verbosity=7
overlay_prefix=rockchip
rootfstype=ext4
fdtfile=rockchip/rk3568-rock-3-a.dtb
overlays=rk3568-pwm8-m0-fan '''rk3568-i2c3-m0'''
rootuuid=ee2ce23a-e0b1-4625-a54b-6ce12c167e97
initrdsize=0x81bfa9
kernelversion=4.19.193-16-rockchip-g0cca7bdf9cdb
initrdimg=initrd.img-4.19.193-16-rockchip-g0cca7bdf9cdb
kernelimg=vmlinuz-4.19.193-16-rockchip-g0cca7bdf9cdb

Then, use mraa-i2c tool to test,we must have a i2c slave device,for example:
root@rock3a:~# mraa-i2c list
Bus 0: id=01 type=linux default
Bus 1: id=02 type=linux
Bus 2: id=03 type=linux

root@rock3a:~# mraa-i2c detect 2
00: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- 68 -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

We use MPU6050 tets i2c.
Modify the macro MPU6050 in '''/home/rock/mraa-examples/i2c_mpu6050.c''' ,as follows to test I2C3m0.

/* mraa header */
#include "mraa/i2c.h"
'''#define I2C_BUS 2'''

rock@rock3a:~/mraa-examples$ gcc -o i2c_mpu6050 i2c_mpu6050.c -lmraa
rock@rock3a:~/mraa-examples$ sudo ./i2c_mpu6050
accel: x:0 y:0 z:0
gyro: x:-10 y:1 z:7

accel: x:0 y:0 z:0
gyro: x:107 y:-12 z:69

accel: x:0 y:0 z:0
gyro: x:6 y:136 z:-50

accel: x:0 y:0 z:0
gyro: x:-5 y:48 z:-103

===== UART test =====
ROCK 3A V1.3 provides 6 UART,There are '''uart0''' ,'''uart3''', '''uart5''', '''uart7''', '''uart8''', '''uart9''' .
If you need the uart function, you can turn on one or more of them.

Firstly, Disable console and enable '''uart0''' for uart test.modify the '''/boot/uEnv.txt''' file to add the following

root@rock3a:~# cat /boot/uEnv.txt
verbosity=7
overlay_prefix=rockchip
rootfstype=ext4
fdtfile=rockchip/rk3568-rock-3-a.dtb
overlays=rk3568-pwm8-m0-fan '''rk3568-uart0'''
rootuuid=ee2ce23a-e0b1-4625-a54b-6ce12c167e97
initrdsize=0x81bfa9
kernelversion=4.19.193-16-rockchip-g0cca7bdf9cdb
initrdimg=initrd.img-4.19.193-16-rockchip-g0cca7bdf9cdb
kernelimg=vmlinuz-4.19.193-16-rockchip-g0cca7bdf9cdb

Here set console to NULL value.

then reboot . use '''ssh''' connect to rock3a in a new window, to send data.

send command follow:
rock@rock3a:~$ sudo mraa-uart '''dev 0''' baud 1500000 send radxa
rock@rock3a:~$ sudo mraa-uart '''dev 0''' baud 1500000 send radxa

Another window sets the baud 1500000 and receives the data by serial console
radxaradxa

===== SPI test =====

Firstly, modify the '''/boot/uEnv.txt''' file.

root@rock3a:~# cat /boot/uEnv.txt
verbosity=7
overlay_prefix=rockchip
rootfstype=ext4
fdtfile=rockchip/rk3568-rock-3-a.dtb
overlays=rk3568-pwm8-m0-fan rk3568-spi3-m1-cs0-spidev
rootuuid=ee2ce23a-e0b1-4625-a54b-6ce12c167e97
initrdsize=0x81bfa9
kernelversion=4.19.193-16-rockchip-g0cca7bdf9cdb
initrdimg=initrd.img-4.19.193-16-rockchip-g0cca7bdf9cdb
kernelimg=vmlinuz-4.19.193-16-rockchip-g0cca7bdf9cdb

then execute command, sync, followed by '''reboot'''.

Create file test-spi.c and add the following contents.

rock@rock3a:~/mraa-examples$ cat test-spi.c
#include <signal.h>
#include <stdlib.h>
#include <unistd.h>

/* mraa header */
#include "mraa/spi.h"

/* SPI declaration */
'''#define SPI_BUS 3'''

/* SPI frequency in Hz */
#define SPI_FREQ 10000000
int
main(int argc, char** argv)
{
mraa_result_t status = MRAA_SUCCESS;
mraa_spi_context spi;
int i, j;

/* initialize mraa for the platform (not needed most of the times) */
mraa_init();

//! [Interesting]
/* initialize SPI bus */
spi = mraa_spi_init(SPI_BUS);
if (spi == NULL) {
fprintf(stderr, "Failed to initialize SPI\n");
mraa_deinit();
return EXIT_FAILURE;
}

/* set SPI frequency */
status = mraa_spi_frequency(spi, SPI_FREQ);
if (status != MRAA_SUCCESS)
goto err_exit;

/* set big endian mode */
status = mraa_spi_lsbmode(spi, 0);
if (status != MRAA_SUCCESS) {
goto err_exit;
}

j = 10;
while(j) {
j--;
printf("0x%x\n",mraa_spi_write(spi, 0xaa));
}
err_exit:
mraa_result_print(status);

/* stop spi */
mraa_spi_stop(spi);

/* deinitialize mraa for the platform (not needed most of the times) */
mraa_deinit();

return EXIT_FAILURE;
}
rock@rock3a:~/mraa-examples$ gcc -o test-spi test-spi.c -lmraa

Then short pin19 and pin21 and run test-spi

rock@rock3a:~/mraa-examples$ sudo ./test-spi
0xaa
0xaa
0xaa
0xaa
0xaa
0xaa
0xaa
0xaa
0xaa
0xaa
MRAA: SUCCESS

===== PWM test =====

ROCK 3A V1.3 provides 7 PWM, '''but only one PWM function can be used at a time currently'''.

Firstly, modify the /boot/uEnv.txt file to add the following

root@rock3a:~# cat /boot/uEnv.txt
verbosity=7
overlay_prefix=rockchip
rootfstype=ext4
fdtfile=rockchip/rk3568-rock-3-a.dtb
overlays=rk3568-pwm8-m0-fan '''rk3568-pwm1-m0'''
rootuuid=ee2ce23a-e0b1-4625-a54b-6ce12c167e97
initrdsize=0x81bfa9
kernelversion=4.19.193-16-rockchip-g0cca7bdf9cdb
initrdimg=initrd.img-4.19.193-16-rockchip-g0cca7bdf9cdb
kernelimg=vmlinuz-4.19.193-16-rockchip-g0cca7bdf9cdb

Modify the macro PWM in /home/rock/mraa-examples/pwm.c as follows to test PWM1_M0.

'''/* PWM declaration */'''
'''#define PWM 15''' //15 means its pin number

Save and compile pwm.c
rock@rock3a:~/mraa-examples$ gcc -o pwm pwm.c -lmraa
rock@rock3a:~/mraa-examples$ sudo ./pwm
PWM value is 0.010015
PWM value is 0.019985
PWM value is 0.030000
PWM value is 0.040014
PWM value is 0.049984
PWM value is 0.059999

===== ADC test =====

connect signal you want to measure, and then compile mraa example c file, aio.c, to test.

rock@rock3a:~/mraa-examples$ gcc -o aio aio.c -lmraa
rock@rock3a:~/mraa-examples$ sudo ./aio
ADC A0 read 20F - 527
ADC A0 read float - 0.51808
ADC A0 read 212 - 530
ADC A0 read float - 0.51906
ADC A0 read 213 - 531

==== test i2c ====
Firstly, modify the /boot/hw_intfc.conf file as following and then reboot to enable i2c2 i2c6 i2c7.
# Hardware Interface Config
# For more details, check https://wiki.radxa.com/Rockpi4/hardware/devtree_overlays.
# Set "on" to enable the optional hardware interfaces while set "off" to disable
intfc:pwm0=off
intfc:pwm1=off
intfc:uart2=off
intfc:uart4=off
intfc:spi1=off
intfc:spi2=off
intfc:i2c2=on
intfc:i2c6=on
intfc:i2c7=on

Then, use '''mraa-i2c''' tool to test,we must have a i2c slave device,for example,we use I2C EEPROM:
rock@rockpi4b:~$ mraa-i2c list
Bus 0: id=07 type=linux default
Bus 1: id=02 type=linux
Bus 2: id=06 type=linux
rock@rockpi4b:~$ sudo mraa-i2c detect 0 //device on bus 0 //i2c7
00: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: 50 51 52 53 54 55 56 57 -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
rock@rockpi4b:~$ sudo mraa-i2c set 0 0x50 0x10 0x55 //write
Device 50, Register = 10, Value = 55
rock@rockpi4b:~$ sudo mraa-i2c get 0 0x50 0x10 //read
Register 0X10 = 0X55

==== test spi====
fristly,modiy '''/boot/hw_intfc.conf''',if use spi1,must disable uart4,if use spi2,disable i2c6.follow:
rock@rockpi4b:~$ cat /boot/hw_intfc.conf

'''intfc:dtoverlay=devspi2''' #spi2

If need debug console, you could uncomment '''intfc:dtoverlay=console-on-ttyS2'''

use '''c''' to test spi,compile spi.c,if use spi1,must disable
root@rockpi4b:~# cat spi.c

/* stop spi */
mraa_spi_stop(spi);

/* deinitialize mraa for the platform (not needed most of the times) */
mraa_deinit();

return EXIT_FAILURE;
}
root@rockpi4b:~# gcc spi.c -lmraa
then short '''pin19''' and '''pin21''' and run a.out

==== test pwm ====

modiy /boot/hw_intfc.conf,if use spi1,must disable uart4,if use spi2,disable i2c6.follow:
# Hardware Interface Config
# For more details, check https://wiki.radxa.com/Rockpi4/hardware/devtree_overlays.
# Set "on" to enable the optional hardware interfaces while set "off" to disablee

Use c program in /usr/local/share/mraa/examples/c/pwm.c to test:

Modify the macro PWM in /usr/local/share/mraa/examples/c/pwm.c as follows to test PWM0. To test PWM1, change #define PWM 11 to #define PWM 13.

'''/* PWM declaration */'''
'''#define PWM 11'''
save and compile pwm.c
root@rockpi4b:/usr/local/share/mraa/examples/c# gcc -o pwm pwm.c -lmraa
root@rockpi4b:/usr/local/share/mraa/examples/c# ./pwm
PWM value is 0.010045

PWM value is 0.050016
PWM value is 0.059956
PWM value is 0.070001
PWM value is 0.080046

==== test uart ====
Disable console and enable uart2 and uart4 for uart test
root@rockpi4b:~# cat /boot/hw_intfc.conf

# Hardware Interface Config
# For more details, check https://wiki.radxa.com/Rockpi4/hardware/devtree_overlays.
# Set "on" to enable the optional hardware interfaces while set "off" to disable.

#intfc:dtoverlay=console-on-ttyS4
root@rockpi4b:~#
then '''reboot'''. Connect your serial line to the corresponding serial port.
use ssh connect to rockpi4,we must have 2 windows(ssh and serial console ),one is for send data,anothor is for receive.

send command follow:
sudo mraa-uart dev 0 baud 1500000 send data
or
sudo mraa-uart dev 1 baud 1500000 send data
receive command follow:
sudo mraa-uart dev 0 baud 1500000 recv 1000
or
sudo mraa-uart dev 1 baud 1500000 recv 1000

the receive window will show the data

==== test adc ====
connect signal you want to measure,and then compile mraa examplec file to test.
root@rockpi4b:/usr/local/share/mraa/examples/c# '''gcc -o aio aio.c -lmraa'''
