Module Factory Reset
If you have console command access, a factory reset can be accomplished with this command:
OVMS# module factory reset
Reset configuration store to factory defaults, and lose all configuration data
(y/n): y
Store partition is at 00c10000 size 00100000
Unmounting configuration store...
Erasing 1048576 bytes of flash...
Factory reset of configuration store complete and reboot now...
That command will erase all configuration store, and reboot to an empty configuration.
If you don’t have console access, you can perform a factory reset by placing an empty file
named “factoryreset.txt” in the root directory of an SD card and insert that SD into the
(running) module. The file will be deleted and the module will reboot within about 30 seconds.
If you don’t have console access (lost module password) and don’t have an SD card, you can
perform a factory reset of the configuration store using the esptool.py tool from the Espressif
ESP-IDF toolkit:
esptool.py
--chip esp32 --port /dev/tty.SLAB_USBtoUART --baud 921600
erase_region 0xC10000 0x100000
Note: the device needs to be changed to the one assigned by your system, i.e. /dev/ttyUSB0 on
a Linux system. After using esptool.py to manually erase_region, you should go into the console
and do the ‘module factory reset’ step to properly factory reset.
