I would like to add an attiny chip to the flex-circuit mod chip, the theory is to add a small second MCU that can be triggered by an application to reset and then burn the bootloader onto the Arduboy.
The advantage of this is you don’t need an additional programmer and go through those steps. You would just have to solder the chip on and then run a specific hex file.
Looking at this right now as a starting point:
This is using it as a usb programmer. I think it could be done with the 85 which has 8k of program memory, so 3k to store the bootloader and a remaining 5k to actually write the bootloading script.
@Mr.Blinky Any thoughts on this?
