=== Description ===
This guide describes how to use the debug serial port as a normal serial port.

* Step 1:Set serial port configuration
sudo su
vim /boot/config.txt

change "dtoverlay=rk3568-fiq-debugger-uart2m0" to "dtoverlay=rk3568-uart2-m0"

reboot

* Step 2:Send data test

If the above configuration is successful, /dev will appear ttyS2

sudo su
stty -F /dev/ttyS2 1500000
echo "uart2-m0-test" > /dev/ttyS2
