Serial debugger garbled data

I have 2 working luckfox cards, I can login into them with SSH and work just fine with ttyS3 and ttyS4, however for some reason I am getting garbled data on serial debugging, I have the correct baud rate and serial parameters. To note that it was working before but now it has stopped working:

This is an example of the garbled data, is this a misconfiguration or a broken card?

Hello, excuse me serial debugging signal garbled phenomenon is all luckfox pico have it? Make sure that the baud rate is 115200 and the serial port is connected correctly. It is possible that the pin is damaged.
