ESP32 Forum

I’m searching for documentation/source code to program the ESP-WROOM-32 FLASH from an external host processor. The host processor runs C/C++ but is not able to run the python programming interface. We would like to program and update the ESP from our host.

Is the documentation somewhere available? And are there other projects/experiences where this is done before?

This is likely useful to you ...

It shows the serial protocol that can used to drive an ESP32 to perform flash programming (amongst other things).
