I replied back to your email on the issue. There is a problem with upgrading U6 firmware on Linux, or perhaps only certain versions of Linux. Linux has problems enumerating the U6 after it is switched to intermediate mode (the mode to write firmware). You can switch it back to normal mode by jumpering a wire between FIO0 and SPC, power cycle your U6 and disconnecting the wire. The Status LED should stay on when it is successfully back into normal mode.
At this time, if you want to upgrade your firmware use Windows or Mac OS X as they do not have this problem.
Thanks for the feedback. I did the jumper procedure and the LED stayed constant. The device appeared to be restored. I think tried programming the new firmware using LJSelfUpgrade on Windows. The programming failed. I went to http://labjack.com/s...users-guide/1.2 (as per instructions). Based on my LED activity, it appears as though the unit has detected internal memory corruption. At this point, the instructions suggest contacting LJ support. Where can I go from here?
