I am running Debian, and have been using J-Link Commander V4.69b for some time, without issue. Today, I downloaded the 64-bit DEB of the latest version (V4.78d) and installed it. When I ran JLinkExe, it attempted to update the firmware, but seemed to be unsuccessful.
After attempting to update, I can no longer communicate with the J-Link at all, I always get a connection error.
The device seems to be enumerated fine, and shows up in lsusb.
However, I can't connect to it. I have also tried running JLinkExe as root, to no avail. I would try an older version of the software, but I cannot seem to find any downloads for old Linux versions, and I do not have access to a Windows installation that I can test with.
EDIT: Additionally, the LED on the device appears to behave the same as before, blinking quickly momentarily, then becoming solid.
