<![CDATA[Force reset M5 stack]]>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

  1. Remove all modules, leaving only the host
  2. Then try to lower the baud rate when burning
  3. If there are wires, you can short-circuit G0-GND before powering on the device and then power on again.0_1711007646460_432299571_430472252787300_1867478767739245481_n.jpg

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
