On of on my pi zero I think my
RXD pin is out. When trying to connect through usb/serial I receive all the loading of the boot and the login console but cannot send anything (thus cannot login).
I tested various different usb/serial cables, all worked on various other pi zero with the same SD card but not with this one. Thus I am almost 100% sure it's the pin.
I read here and there that other pins can be use as alternative
UART. I guess than that I could connnect my USB/serial cable to this other pin, but I didn't find any explanation on how I should process to tell the pi to use another port as
