Factory reset
|
|
=============
|
|
|
|
If something unexpected happens and your ESP32-based board no longer boots
|
|
MicroPython, then you may have to factory reset it. For more details, see
|
|
:ref:`soft_bricking`.
|
|
|
|
Factory resetting the MicroPython esp32 port involves fully erasing the flash
|
|
and resetting the flash memory, so you will need to re-flash the MicroPython
|
|
firmware afterwards and copy any Python files to the filesystem again.
|
|
|
|
1. You will need the Espressif `esptool`_ installed on your system. This is the
|
|
same tool that you may have used to initially install MicroPython on your
|
|
board (see :ref:`installation instructions <esp32_flashing>`).
|
|
2. Find the serial port name of your board, and then use esptool to erase the
|
|
entire flash contents::
|
|
|
|
esptool.py -p PORTNAME erase_flash
|
|
|
|
3. Use esptool to flash the MicroPython file to your board again. If needed,
|
|
this file and flashing instructions can be found on the `MicroPython
|
|
downloads page`_.
