Set Flash Voltage

The espefuse set-flash-voltage command permanently sets the internal flash voltage regulator to either 1.8V, 3.3V or OFF. This means a GPIO can be high or low at reset without changing the flash voltage.

Positional arguments:

• voltage - Voltage selection [‘1.8V’, ‘3.3V’, ‘OFF’].

Note

Setting flash voltage is not supported on ESP32-C61. The tool prints the error set-flash-voltage not supported!.
