Hi,

As I didn't see any further replies to this post I wonder did some someone got this accomplished.

The goal is to be able to flash the ESP32 via UART with a microcontroller.

Appreciate any help given.

Thanks

I've been working on something that could do this. Right now its a simple arduino sketch that can grab a bin from say an SD card and upload to an esp32 connected over UART. It kind of works but every so often I get an error code that doesn't exist on the Serial Protocol wiki :cry:. The 8266 seems to work fine

mind sharing or advising the cost of your code ?

I'll post with a github project when it's done. Still making sure it all works then need to clean up code.
