Hi
Is it possible to configure UART2 as being “Tx-Only”, i.e. allow it to be used to spew logging information, but ignore any incoming data?
e.g. If I open GPIO14, would it kill the UART and prevent it from transmitting on RxD2? Or would it silence the receive side of the UART but still allow the transmit side to work?
I don’t have the Q26 spec to hand - is GPIO14 “multiplexed” with one of the other UART2 signals?
Yes it is. Although I don’t appear to be able to open GPIO14, even with UART2 disabled. So it’s going to be a splashpad on the PCB, and leave the input floating…
