I can confirm that the J-Link OB firmware compiled Feb 12 2016 12:15:53 is compatible with v6.12a, see screenshot below.

@Bjørn, Thanks for determining this info.

Yes I have tried an earlier version of firmware, wit J-Link Driver v6.12a, however that is when I got the following response:

WARNING: Out of sync , resynchronizing...

I then had the unlikely thought that perhaps J-Link Driver v6.12a wasn't backward compatible with earlier firmware drivers! which is very unlikely. So then started investigating how I could un-install J-Link Driver v6.12a and move back to J-Link Driver v6.10m, which I suspect I'll have to continue trying todo.

Yes the board was successfully in BOOTLOADER mode, but thanks for enquiring. Could you perhaps back version your firmware and see if J-Link Driver to v6.12a still works for you?

(I get the feeling there is some piece of the puzzle that I am not understanding)

I just got a reply from the nrfjprog developer and there appears to be some bugs with the firmware compiled Nov 14 2016 16:58:29 so it will not be released until these have been fixed. He recommended that you use the latest available firmware from our site. Lastly, when you're drag and dropping the .bin file to the nRF52 DK, are you putting it in bootloader mode first by holding down the reset button while power-cycling the board?

@Bjørn, Thanks for actioning the updated firmware. My PCA10040 is V0.9.0 - 2015.41 - 682336494. I got it when I attended the Nordic Global Tech Tour UK back in 2015.

The J-Link OB firmware compiled Nov 14 2016 16:58:29 .bin file hasn't appeared yet. Fingers crossed that I can drag, drop & upgrade successfully. I will monitor the download area. Appreciated.

I updated my J-Link Driver to v6.12a and was prompted to update the J-Link firmware to OB-SAM3U128-V2-NordicSemi compiled Now 14 2016 16:58:29. I have no issues connecting to my PCA10040 v1.1.0 with JLink.exe. Which PCA10040 version are you using? I have also requested that the latest J-Link OB firmware is made available on our site.

@Bjørn, I think I possibly understand path that I took that has got me in this mess!

I installed the latest macOS J-Llink which is V6.12a
I purchased an nrf51 Dongle and installed nrfConnect
nrfConnect detected and updated the J-Link firmware in the nrf51 Dongle (PCA10031) this went to Connectivity firmer version 1.0.0
I connected nrfConnect to the PCA10040 (nrf52 board) and accepted its offer to upgraded the firmware in that too. I think this is when thing stopped functioning correctly.

Since then all my attempts to communicate with the PCA10040 using J-Link have failed. I have tried to modify the J-Link firmware using the Drag and Drop method, which appears successful, however them when running J-Link I get the following output repeated:

Connecting to J-Link via USB...

WARNING: Out of sync , resynchronizing...

You can find the previously released versions of the firmware by clicking on the version number, here is the link to the page showing the older versions of the J-Link OB firmware. However, it does not look like we have released any new firmware between 28th August 2015 and 2nd December 2016.
