ESP32 bootloader

Development Boards ESP32

Hi,

I want to use an ESP32 module (the one used in Sparkfun thing plus) in our custom PCB design and I was wondering where i can get the bootloader file from (which you are using in your dev board) so that Arduino IDE can recognize as Sparkfun Thing Plus. I am going to Arduino IDE to program the ESP32 module, but before that I’d need bootloader (some .bin). I’m having hard time to find that file or which resource/tool I have to use. Can you please provide any information on that? I’d appreciate that.

Thanks,

Akshay

Hi Akshay.

I’m looking at the build files for this and it doesn’t look like we put any bootloader on these at all, we just use the one Espressif ships these with.
