Re: CRio Connection: Buggy

I don't think the logs I captured are particularly useful, and they weren't comprehensive.
I had to bring in several other laptops after the problem occurred to start the monitoring.

This particular log shows two boots, but unfortunately the problem may have been fixed by this point.
The first boot generated the 4 flashes, and caused an automatic reboot.
The second boot was a successful recovery from the same.

I have had several other cRIOs reimaged without any issues. Maybe one 4-flash that caused a then successful reboot.

In the case I saw, the v27 reformatting enabled NetConsole, and had None for CAN.
Cycling the power had no affect and the 4-flashes continued unabated.

Changing DIP switches, e.g., Safe Mode, didn't seem to affect the 4-flashes and the cRIO remained unresponsive.
The flashes began very quickly, so it may be before any image gets loaded or early in the load process.

Reimaging (from same Classmate) with v27 completed successfully, but had no affect.

Reimaging to v25 worked, then a repeat of v27 was successful.

--------
On a side note, Classmates that installed the LabVIEW Update, but didn't install the LabVIEW DVD, look normal from a distance.
I had to be there to notice all the missing software, but the version information was right up to date...
