Problem with avr-debugger on Arduino Mega2560

PlatformIO IDE

Good morning,
I fired all the Serials. of my project but I still get this error message when compiling:

Can you help me ! Thanks

It’s still referencing the Serial object somewhere.

Do you have the code?

Also note that, since the ATMega2560 has multiple hardware serials, you can actually chose to run the avr debugger on a different hardware serial – if you do though, you will have to connect an external USB-to-UART probe there to reach it.

Thanks for your message.
I’ll check again, but I had eliminated the Serial objects from my program.
They were also useless.
