apt-get install esptool

Descargamos el firmware:

https://micropython.org/download/esp32/

Descargo este:

 GENERIC : esp32-idf3-20210202-v1.14.bin

Para borrar la memoria. Si no sabemos el puerto, no lo ponemos y lo detecta, es /dev/ttyUSB0:

esptool erase_flash

esptool.py v2.8
Found 1 serial ports
Serial port /dev/ttyUSB0
Connecting........_
Detecting chip type... ESP32
Chip is ESP32D0WDQ6 (revision 1)
Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None
Crystal is 40MHz
MAC: f0:08:d1:d3:1e:98
Enabling default SPI flash mode...
Erasing flash (this may take a while)...

A fatal error occurred: ESP32 ROM does not support function erase_flash.

Da error. Subimos el firmware que hemos descargado. Tarda un poco. Debería devolver un prompt pero no hace nada:
