Rock64 v3 Tx/RX and GPIO connections for 3dprinter
01-13-2026, 07:22 PM
I used armbian-config to reinstall the latest kernel V6.12.57
Is there anything else I have to do to turn on the UART2 pins?
Is there any way to test whether the pins UART2 are working on the board?
or see activity, with a command line, when plugged in.
I saw something about looping the pins with a wire for an "echo" test, but it wasn't explained well enough for me to try.
