Paid job : bootloader modification


I've definetly not enough skills to do what I want : a bootloader for the arduino Zero, whithout the UART part (that is easy to remove), but with SD card loading capability.

I want to have a function that I can call in any arduino program that take a file name as parameter and then loads the file_name.hex or .bin in the flash of the mcu.

I already gathered some code and documentation about a SD card bootloader for samd20. So I guess this is a good basis for this project.

Let me know if you're interested.
