== Work with ROCK Pi N10 Debian ==

=== Introduction to ROCK Pi N10 Debian ===

ROCK Pi N10 Debian  is an easy to use desktop system. While working with ROCK Pi N10 Debian, you will find it do well on playing music, Internet, Bluetooth, AI and so on.

ROCK Pi N10 Debian uses '''systemd''' to manage system.

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

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

Check [[rockpiN10/dev/serial-console | Serial Console]]

==== Option 2: SSH ====
SSH server  is enabled on port 22 of ROCK Pi N10 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

===Desktop ===

The preinstalled Desktop is xfce4.

=== Install and update  necessary packages ===

Add Radxa APT, see [[rockpiN10/radxa-apt | Radxa APT]].

Install packages;

  $ sudo apt-get update
  $ sudo apt-get install -y rockchip-overlay
  $ sudo apt-get install -y linux-4.4-rock-pi-n10-latest

=== Network Connection ===

There are two methods for network connection. One is Ethernet and the other is WIFI.

==== Ethernet Connection ====
You can use a network cable (one end connected to the external network port or route)  to connect your ROCK Pi N10 to the network. The ROCK Pi N10 will automatically configure the network for your surfing on the Internet.

===== To test the Ethernet, we need to follow the steps: =====
* 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, 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

==== WIFI Connection ====

When there is not a network cable for your ROCK Pi N10 the WIFI connection is another good choice. ROCK Pi N10 supports 2.4G/5G WIFI wireless network.

=====To test the WIFI performance, we need to follow the steps:=====

* Switch to super user mode
  $ sudo su

* Open the WIFI
  $ nmcli r wifi on

* Scan WIFI
  $ nmcli dev wifi

* Connect to WIFI network
  $ nmcli dev wifi connect "wifi_name" password "wifi_password"

* Test WIFI perpormance by tool iperf.

=== Bluetooth ===

Check Bluetooth service

  $ systemctl status bluetooth

Run Bluetooth service if the Bluetooth service is inactive.

  $ systemctl start bluetooth

Check Bluetooth device

  $ hciconfig
  hci0:   Type: Primary  Bus: UART
          BD Address: 22:22:70:B2:10:6F  ACL MTU: 1021:8  SCO MTU: 255:12
          UP RUNNING 
          RX bytes:1399 acl:0 sco:0 events:45 errors:0
          TX bytes:3458 acl:0 sco:0 commands:45 errors:0

=== NPU ===

Related package: rockchip-npu

Use root user mode
  $ sudo su

Update package

  apt-get install -y rockchip-npu

Init NPU GPIO
 
 npu_powerctrl -i

Power up NPU

  npu_powerctrl -o

Scan NPU

  lsusb
  [  839.258118] usb 8-1: New USB device found, idVendor=2207, idProduct=1808

Upgrade NPU firmware

  npu-image.sh

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

The ROCK Pi N10 system images use configuration file /boot/uEnv.txt.

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

For more details about device tree overlays, see [[Device-tree-overlays | Device Tree Overlays]] and [[RockpiN10/dev/libmraa | ROCK Pi N10 Libmraa]].

==== I2C ====

To enable I2C-2 (/dev/i2c-2), add item "rk3399pro-i2c2" to the "overlays=" line. 

  overlays=rk3399pro-i2c2

To enable I2C-6 (/dev/i2c-66), add item "rk3399pro-i2c6" to the "overlays=" line. 

  overlays=rk3399pro-i2c6

To enable I2C-7 (/dev/i2c-7), add item "rk3399pro-i2c7" to the "overlays=" line. 

  overlays=rk3399pro-i2c7

==== PWM ====

To enable PWM0, add item "rk39999pro-pwm0" to the "overlays=" line.

  overlays=rk3399pro-pwm0

To enable PWM1, add item "rk3399pro-pwm1" to the "overlays=" line.

  overlays=rk3399pro-pwm1

==== SPI ====

To enable SPI1, add item "rk339pro-spi-spidev" to the "overlays=" line.

  overlays=rk3399pro-spi-spidev
  param_spidev_spi_bus=1
  param_spidev_spi_cs=0
  param_spidev_max_freq=10000000

==== UART ====

To set ttyS4 as common serial communication devices, add these items "rk3399pro-uart4" to the "overlays=" line. The device /dev/ttyS4 is available.

  overlays=rk3399pro-uart4

=== IR Remote Control ===
