ROCK Pi E exports a dedicated serial console, which can access the low level debug message.

== Requirement ==

* ROCK Pi E
* USB Type-C power adapter and USB Type-C cable
* Host PC with Windows or Linux
* USB to TTL serial cable
** The definition of each pin of USB to TTL cable is showing like this:

[[File:usb2ttl-cable-definition.jpeg | 500px ]]

=== Note ===

* The default baudrate of ROCK Pi E is 1500000(1.5Mbps), please check if your USB to TTL cable support 1.5Mbps baudrate. Some model of [https://www.silabs.com/products/interface/usb-bridges CP210X] and [http://www.prolific.com.tw/US/ShowProduct.aspx?pcid=41 PL2303x] have baudrate limitation, please check the specified model. We also tested that some cheap PL2303x based cable does not work well. Make sure choose a high quality one. The instructions below use a [http://www.ftdichip.com/Products/ICs/FT232R.htm FT232RL] based cable.

* It seems that the serial tool on macOS platform can not support custom baudrate such as 1.5Mbps due to driver restriction. If you know how to set custom baudrate on macOS, please add an item here to show your findings.

== Connection ==

Connect the USB to TTL serial cable as below. '''Don't connect the red wire.'''

* ROCK Pi E V10 Board and later

|-
| RX(pin 10) || <---> || Green wire
|-
| TX(pin 8) || <---> || White wire
|-
| GND(pin 6) || <---> || Black wire
|}

== Serial setting on host PC ==

The default serial setting for ROCK Pi E u-boot and kernel console is:

baudrate: 1500000
data bit: 8
stop bit: 1
parity : none
flow control: none

=== Linux ===

Minicom is the serial tool that supports wide range baud rate.

Install minicom:

sudo apt-get update
sudo apt-get install minicom

Plug in the USB to TTL cable, kernel `dmesg | tail` should show the following device:

[1036835.654076] usb 1-6.4.3: new full-speed USB device number 103 using xhci_hcd
[1036835.755730] usb 1-6.4.3: New USB device found, idVendor=0403, idProduct=6001
[1036835.755732] usb 1-6.4.3: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[1036835.755733] usb 1-6.4.3: Product: USB <-> Serial
[1036835.755734] usb 1-6.4.3: Manufacturer: FTDI
[1036835.756728] ftdi_sio 1-6.4.3:1.0: FTDI USB Serial Device converter detected
[1036835.756750] usb 1-6.4.3: Detected FT232BM
[1036835.757195] usb 1-6.4.3: FTDI USB Serial Device converter now attached to ttyUSB0

'''/dev/ttyUSB0''' is our device here.

==== Setup minicom====

First add current user to plugdev group to use minicom without sudo or root.

sudo usermod -a -G plugdev $USER

Edit your '''~/.bashrc''' and add the following line with some default parameter

alias minicom='minicom -w -t xterm -l -R UTF-8'

Login to a new terminal to take effect.

Create and edit file '''~/.minirc.rockpiS''', add the following content:

pu port /dev/ttyUSB0
pu baudrate 1500000
pu bits 8
pu parity N
pu stopbits 1
pu rtscts No

Now run '''minicom rockpiE''' to use the config above and connects to the ROCK Pi E serial console.

=== Windows ===

Putty is also great serial tool that supports wide range baud rate.

Plug in the USB to TTL cable to you windows PC. Viewing the '''device manager''' you can find the '''COM number'''. Here it is '''COM3'''.

Launch the application Putty on your windows PC. And do the setting as follows:

For category '''Session''', set '''serial line''' as COM3, '''speed''' ad 1500000, '''connection type''' as Serial.

Write '''rockpiE''' in the '''Saved Sessions''' column and press '''Save'''.

[[File:putty-setting-session.jpg | 500px ]]

For category '''Connection---Serial''', do the setting:

[[File:putty-setting-serial.jpg | 500px ]]

Once finish the setting, press '''Open''' button to start.
