Bootloader from SD card

  • Hello all !
    I research "Bootloader Arduino from file hex in SD card. Who had already done this ? Might you help me ? Thanks somebody

Something like this?

I assume you mean

Which is where the links point.

Other than it was documented, with full code on

Is there a specific question that needs to be answered?
