ESP32 Bootloader

[DaneSlattery]

Hi @bjoernQ

I am curious where you acquired this bootloader.bin, and if it was possible to include instructions to build it? I would like to build a bootloader to support OTA updates for the no-std esp32 environment, but I am so out of my depth. Any idea if there is work on an OTA bootloader?

Hi @DaneSlattery,

if you just need a bootloader.bin for ESP32 there is a branch here: https://github.com/bjoernQ/esp32c3-ota-experiment/tree/esp32

In general, it's the bootloader built by esp-idf. If you have everything on your machine to build esp-idf projects you could cd into examples/system/ota/simple_ota_example and build the example. Afterwards you should find the bootloader.bin in build/bootloader

Good suggestion to add this information to this repo's README 👍
