If you ever find you have gotten your board into a bad state with CircuitPython – Maybe you accidentally got it stuck in read-only mode or maybe it’s stuck in a boot loop, you can put your board into safe mode which will boot the board, but not run any of the code. You can then fix your issue and reset the board.
To get into safe mode, follow these steps:
- 1. Press the [RESET] button to reset the ESP32 chip
- 2. After the RGB LED has gone purple and then off, press and hold the [BOOT] button for a few seconds
Your board should now be in safe mode.
