Serial Terminal

Introduction

The usb-c port on the Jetson exposes a serial port we can use to gain access to a shell on the Jetson

Setup

  1. Connect your device to the usb-c port on the jetson
  2. use a serial terminal client of your preference, this guide uses minicom
sudo apt install minicom

sudo minicom -D /dev/ttyACM0 -b 115200 -c on
# NOTE: if you don't see a prompt to login hit enter and it should pop up

# use ctrl-a x to exit
  1. Serial terminals do not communicate the size of the client or any dynamic changes to the window size. As such you may see weird text behavior or formatting. Use the resize command to resize the serial terminal to the current size of your terminal window

convenience Features

create a config for the Jetson

echo -e "pu port             /dev/ttyACM0\npu linewrap         Yes" | sudo tee /etc/minicom/minirc.jetson > /dev/null

now you just have to do

sudo minicom jetson -c on
