Same thing. Also results in endless loop of the FW if I connect it to PD2/PD3...

Update: Connected it still same as above to PD0 PD2 PD3 PD4 and PD5 now (for enable pin), and set the config differently now to mserial5 like below: Now the...

Update: I now soldered also the small solder pad to enable UART on the Pin 5 like described in the thread linked in the previous post and also here https://de.aliexpress.com/item/33025720969.html?af=701906&gatewayAdapt=glo2deu....

I am not sure, think that was just a display issue of VS code here, cause normally if I don't define Z2_SERIAL_TX/RX_PIN it will give me compilation errors. If I...

No did not try swapping them, but I will try that and also give it a try with MSerial2 later! Thanks for the hints!

Swapped PD2 and PD3 defines now without using MSerial, but only the RX / TX defines - same story (FW freezes, as written in the initial post). Next I will...

No success. Also swapping RX TX physical pins results in same error as before...
