PCA10028 not functioning

[Vala]

Hi,

I have a PCA10028 board. When I connect it to a computer the LED LD5 doesn't turn on at all, and no new USB connection pops-up in my computer. But when I connect it with boot loader mode, by pressing the reset button and power cycle the board, the computer recognizes it and the LED starts blinking.

I have another board with the same model and version and it works fine. So no problem about drivers. It seems that there is a problem with the board.

Anyone has any idea about this? How can I fix my first board?

Thanks.

Hi

We have seen similar problems before and it is most likely an issue with J-Link. Have you tried to update the J-Link FW? Just drag-and-drop the .bin file in my link onto the DK bootloader drive. Sometimes we have had to use a different computer to update the FW.

Thanks. Your solution worked. I downloaded the file from your link and simply did the drag and drop in the boot loader drive.

Regards.
