ESPFlash

ESP8266 and ESP32 serial flasher based on esptool.py.

• espflash library & binary
• espflash cargo subcommand

Status

Flashing should work for both ESP32 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.
