On-Board programmer erased, How to reflash it? What to reflash?

On a NRF52DK Board, There is an on-board programmer done with ATSAM3U2C seen as a Segger programmer or a Jlink Progammer.

By mistake, I erased the entire flash of this programmer. I know it's possible to change its firmware with the IF BOOT/RESEST Boutton. But i think I erased the bootloader that allow that.

I'm trying to reflash it through Sam-ba bootloader of Atmel but I can't find a firmware that boot correctly. I tried this firmware and this one

But It doesn't seem to boot.

  • Hey JC, From what I have understood, I think you are unable to program the device. I would recommend performing following procedure:

    1. Check if the device is listed in Device Manager. If yes, does it have an exclamatory symbol?

    2. When you plug your device into the system, does a directory open which includes SEGGER.html, MBED.html, USER GUIDE.html and README.txt. Also, if the directory does not open on its own, check if a new drive has appeared in your system.

    3. Follow Gaute Gamnes's procedure mentioned here
