nRF52 preview dev.kit - unable to j-link nRFgo auto-firmware update

[labaip]

Hello, my nRF52 Preview dev.kit don't upload the last 2016 march 15 firmware update from nRFgo app. It gives me always an error and the progress bar stay at 0% value.

I tryed manually (IF boot button at power on procedure) with all old firmware release I could find to download , and these firmware were loaded correctly , so I don't think about a hardware issue of my dev.kit.

But I cannot find the latest "J-Link OB-SAM3U128-V2-NordicSemi Mar 15 2016.bin" file anywhere in nordic site. Is there a place where I can download it ?

Thanks Maurizio

It looks like we do not have the latest version of the jlink FW on our webpage. I guess it is assumed to be covered by the 'auto' update functionality. I would suggest to download and install the latest Jlink Drivers, then attempt to update the FW by programming something through Keil and see if you get the same result.

Update:

I was able to get a hold of the latest binary: J-Link OB-SAM3U128-V2-NordicSemi 160315.bin

Update 9/10-17:

Latest FW for Segger J-link v.6.12e: J-Link OB-SAM3U128-V2-NordicSemi 160914.bin

160308 is loaded correctly ... but it's not the latest version . The latest is 160315 , so nRFgo continue to try auto-update and fail.
