I see that you were able to figure it out completely without my help as well. I'm glad you got the issue resolved at that you can now focus on actually working with the kit. Thank you very much for the update and feedback on what was actually causing this. Hopefully it's not something that more people will run into.

SOLVED: My problem turned out to be caused by an old version of JLinkARM.dll that was being used by Keil from C:\Windows\SysWOW64 instead of C:\Keil_v5\ARM\Segger where I assumed it was pulling from. I manually updated it (copy/paste) to the one from the Keil directory and the board was recognized. Thanks @Asbjørn for your help!

@Asbjørn I can post screen shots, but they would be identical to those in andreas post (except in english). The only difference I'm aware of between the machine on which it works and the others is the Windows version: the working one is Windows Home Premium 64, the others are Windows 7 Professional 64.

Just tried updating J-Link to 4.96f - no change. I'm having the same problems as @andreas and trying the same troubleshooting steps as described in the post here: devzone.nordicsemi.com/.../

Sorry, you are correct, I misunderstood your setup. You say that you have tried it on three different computers in total. On one it works, on the other two it doesn't? Are there any differences when it comes to these computers? I'm just trying to figure out how I can reproduce the issue here. Can you post screen shot of the view/error messages you get in Keil when it's not working?

As stated, my Rigado module works as expected, there's no need to fix it. The problem is with the nRF51 DK. I did try flashing the nRF51 interface MCU firmware with J-Link OB-SAM3U128-V2-NordicSemi 140918.bin, but it didn't fix the problem. Thanks

@srobison: I think your issue is related to the J-Link Interface MCU Firmware on your Rigado module. I initially thought that your issue and the one that @Andreas reported was the same thing, but they can't be. So in order to fix your Rigado module you should download the latest J-Link interface MCU firmware from here: www.nordicsemi.com/.../38671

Put your Segger into bootloader and then drag and drop or copy the new file into the Bootloader disk driver that will appear. A few seconds (5 seconds) after you have copied the file into the bootloader drive, you can toggle power on the board and you should be asked for updating the Segger drivers next time you start Keil and everything should be working. On the nRF51-DK you can enter bootloader through holding down the "reset" button on the Segger when you toggle power on the nRF51-DK itself. The LED (LD5) will start blinking slowly when it's in bootloader mode. I assume there's a similar mode on the Rigado board as well.

Just wanted to throw a heads up in there. We here at Nordic are working on it, but it's a difficult scenario to re-create as of right now. We have seen a couple of similar scenarios where nRFtools needed to be re-installed for it to work on Keil 5.13 and then re-booting the computer, but we have yet to confirm that this is the main issue here. It could be related to the MDK version from the SDK as well or the Segger drivers, Will report back as soon as possible.

Same story on my end. Suggestion to my request was trying uVision 5.12. That was confirmed working with nrf51-dk by other users (at least for windows version different to win8).

I hvae been looking around on the Keil site, but wasn't able to download older versions so far.
