ATSAM3 MSD bootloader
Hello, this is my fist question here, I would really appreciate your help.
So, to sum up my problem, I have NRF51-DK development kit from Nordic and I accidentally "fried" the board by high voltage (12V) somehow got onto the SWD interface pins. I therefore un-soldered both the NRF51822 chip and interface MCU. I bought a new interface IC, the ATSAM3U4, which is basically the same as the original ATSAM3U2 which was originally on the board, except it has dual bank flash, but in my opinion, it shouldn't make any difference in operation.
And now for my question. I have downloaded CMSIS-DAP project from gitlab and I appear to be stuck ever since. How can I reflash the stock bootloader on the interface MCU from SAM-BA to mbed's MSD bootloader? I was trying to set the start and size of the flash and RAM in keil but with no success. I keep getting the 'No algorithm found for the range' error. Is there any documentation about flashing the MSD bootloader onto interface MCU? I don't seem to be able to find any and I am a bit confused by flashing procedure.
Thank you, Matic
