Hi,

You can find the bootloader for the onboard debugger here (or more specifically here). Once you have flashed that, you can use this j-linky .hex file: devzone.nordicsemi.com/.../3566.J_2D00_Link-OB_2D00_SAM3U128_2D00_V2_2D00_NordicSemi-160315.bin

That is the problem, I'm using the DK to program a nRF52832 in a custom design.

Thanks for your response.

That would be the Segger. You could replace it but then you wouldn't have the firmware since it is proprietary to Segger and is not published. You will have to buy new DKs to solve your problem.
