I have a project in which I need to change the Arduino software without the need to be connected by USB.
From what I've been looking at may have 2 options, you flash the Arduino from SD, or read the Arduino software directly from the SD.
For any of the 2 options would need to create a bootloader (For the first option 2boot there, but I can not get it to work). Can anyone help me?
We could talk about paid work.
Regards and thanks!
