Hi there,
I have been using J-Link equipped Nordic nRF52 development boards for about two years. I've had no trouble until now. I upgraded to Ubuntu 17.04, and JLink 6.16b, and now I've lost the ability to communicate with my devices. Please have a look at the following terminal log:
> john@john-Z97X-UD3H-BK:~$ JLinkExe -device nRF52
> SEGGER J-Link Commander V6.16b (Compiled Jun 9 2017 18:05:08)
> DLL version V6.16b, compiled Jun 9 2017 18:04:56
>
> Connecting to J-Link via USB...FAILED: Cannot connect to J-Link via USB.
> J-Link > exit
I'm confident that my dev boards are good. I have a few of them. They all register a JLink mass storage device when they are connected to USB. We have a Windows laptop which can flash them just fine.
Someone on the Nordic web site suggested that I might have "the udev problem." I have seen many references to problems related to udev here on the Segger forums. But not too much of that advice is recent, and none of it is very general. So I'm not sure whether it applies to me.
Any advice you might have would be greatly appreciated. Thanks!
