[SOLVED] nRF52832 DK bricked?

[Steph van Schalkwyk]

My nRF52832 DK will no longer respond to J-Link downloads. 

It seemed to start after I erased the target from Segger IDE.

Now it states that the file is downloaded, but on debug it stops at FEFEFEFE.

Is there a hex file I should download to the DK to restore it?

[SOLVED]

When one uses Segger IDE to erase a device, it whacks the entire device.

This restores it (using s212):

$ nrfjprog -f NRF52 --program ANT_s212_nrf52_5.0.0.hex --log --chiperase
Parsing hex file.
Erasing user available code and UICR flash areas.
Applying system reset.
Checking that the area to write is not protected.
Programing device.

I tried "nrfjprog --recover -f nrf52" and it returns immediately with this:

Recovering device. This operation might take 30s.
Erasing user code and UICR flash areas.

Should I wait 30s for the device to recover? Seems odd.

I can program hex files such as sniffer*.hex. The LED blinks, so it may be working. However, Segger IDE cannot program this board trough J-Link.

I'm glad you were able to solve the problem, thanks for sharing your solution.

Cheers.
