I mistakenly applied 5V to the MC60 module, while programming it. The module was successfully programmed, but after that, the LED connected to the NETLIGHT pin did not light up. On the other hand, I can’t see the debug messages that are sent through the uart properly and I see meaningless expressions. The codes have no problems and the debug messages are correctly seen on the other module. Is it possible that the module was damaged due to the application of a few moments of overvoltage? If the UART part is damaged then why can I still program the module?
Thanks in advance.
