PCA1004 board become brick, How do I make the board alive again?

[willyoda]

I have already explored how to fix the related problem in the DevZone. I think the firmware of the  ATSAM3U2CA-AU is erased. Here, I have two problems:

1, How can I get the firmware?

2, How can I update the firmware into the ATSAM3U2CA-AU?

3, is there another way to make my PCA10004  board relive ？

Hi, You could try to put the debugger chip in DFU mode by holding the reset button while power cycling it. It will show up as a mass storage device on your PC and you can copy/drag this firmware file (3566.J-Link OB-SAM3U128-V2-NordicSemi 160315.bin) using for instance windows explorer to program it.

Thank you very much. I am successful to make my board kit alive again.
