ESPFlash

ESP8266 and ESP32 family serial flasher based on esptool.py.

• espflash library & binary
• espflash cargo subcommand

Status

Flashing should work for ESP32, ESP32-S3, ESP32-C3, and ESP8266.

If you have an ELF file that flashes correctly with esptool.py but not with this tool then please open an issue with the ELF in question.
