Force reset M5 stack
keptan last edited by keptan
After inadvertently uploading a sketch that outputs to wrong pin numbers one of our M5 stacks has become un-uploadable. That is whenever it's given power the speaker emits loud continuous buzzing and the hardware won't show up as a serial port.
Is there anyway to force hardware into an uploadable state and reset.
Hardware is original M5 stack without 4mb psram

We managed to fix it
simply holding down button A and reset button until Arduino ide attempted to connect
then releasing it and allowing it to upload without a chance for the old code to run
