Thanks to everybody for their suggestions, but I still can't get my OPLind working. It worked fine for a couple of months until I disconnected everything from my Revo board, removed it from my vehicle, and froze it to calibrate the thermal sensor. My process for attempting to get it working again has been:
I've "Upgraded and Erased" several times. The sequence of events is:
1. Starting Upgrade and Erase with the board unplugged.
2. Plugging it in before it times out, with the Windows connection tones announcing a connection.
3. The upload progress bar shows 100% loading with a second LED on the lower right of the board blinking, followed by the "Rebooting and erasing the board, please wait" message, accompanied by a "disconnect" tone.
4. After about 10 seconds, the "No link" message in the system health box at the upper right changes to "Log replay" flanked by a couple of flashing dots after a few more seconds.
5. After about 45 seconds, the upload progress bar is replaced by a Timed Out message that advises to manually upgrade the board.
I've checked with Device Manager, and it says the OPLinkMini virtual COM port device is working properly.
When I try the "Rescue" option on the download screen, it shows the device information, with a "ready" message, but no file loaded.
There is also a "running" message adjacent to the buttons at the top of the left window, and the system rescue instructions on the lower part of the screen states that is has found 1 device.
I'm obviously missing something or my Mini ground station has gone south.
Is there anything else I can do before I order another OPLink?
Thanks again.
