Нужна помощь Стереть прошивку esp8266

[lmasikl]

Здравствуйте.
Пытаюсь стереть прошивку используя GitHub - espressif/esptool: ESP8266 and ESP32 serial bootloader utility

esptool.py --port /dev/ttyUSB0 erase_flash

Получаю вот такой вывод

esptool.py v2.2
Connecting...

A fatal error occurred: Failed to connect to ESP8266: Timed out waiting for packet header

На попытку залить прошивки вывод аналогичный.

Подскажите рецепт или в какую сторону копать
