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 ？

How colud erase firmware? It is not possiable i think. Maybe your problem about hardware. I suggest check your hardware.

My colleague powered on when the RESET key was pressed, then the board is identified by PC no more. I had checked the power VDD, 5V if I still used the USB port(J2)  to apply power, they are work normally. when I use jLink lite to download the image hex file to nrf52832, the tool popup a dialog, it info me that I need to input IP  and other info. So I think the firmware of the ATSAM3U2CA-AUthe is gone.
