Please describe your issue below:
Using this method, I successfully established UART communication via pins 15 and 16.
What I’m further curious about is whether I can utilize the remaining unused GPIO pins to build additional UART communication channels.
With UART_C enabled, can I use the remaining free GPIO pins like 35, 37, and 39 to implement additional UART communication or similar functions?
It seems possible if I use the “Device Tree Overlay” correctly, but I’m unsure how to implement it.
