What should you do if your Adafruit ESP32-S2 tft Feather is locked up.
Hold BOOT while pressing reset. It doesn't show as a drive but as a serial port. You can try installing an Arduino program; that way should reinstall the bootloader too. This probably wont work. On a MAC it might show the drive mounted.
