Introduction¶

ROM loader for ESP chips, works with ESP8266 or ESP32. This is a ‘no-stub’ loader, so you can’t read MD5 or firmware back on ESP8266.

See this document for protocol we’re implementing: https://github.com/espressif/esptool/wiki/Serial-Protocol

See this for the ‘original’ code we’re miniaturizing: https://github.com/espressif/esptool/blob/master/esptool.py

There’s a very basic Arduino ROM loader here for ESP32: https://github.com/arduino-libraries/WiFiNINA/tree/master/examples/Tools/FirmwareUpdater

Dependencies¶

This driver depends on:

Adafruit CircuitPython

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Installing from PyPI¶

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-miniesptool

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-miniesptool

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-miniesptool

Usage Example¶

Check the examples folder for demo sketches to upload firmware to ESP8266 and ESP32
