I accidentally connected UART wires one row lower than it should be (see image): then I unplugged them shortly after that and then connected correctly, but serial console doesn't work anymore. USB was not connected at all, so pi was powered over GPIO. I've looked at a several posts where people bricked their zero's totally, but my zero works fine except UART and maybe GPIO at all but I don't know how to check latter.
- Can Pi zero 2W be recovered after this kind of UART connection?
- How can I diagnose if UART is really dead? Maybe check any pins with a multimeter?
- I also think this is result of a static charging. How can I check that and/or discharge PCB?
