I just thought of another possible problem. I have the panelolu2 LCD panel that I soldered together and the firmware is configured for this. But when I power up the unit with the panelolu2 connected the back linght comes on for a few seconds and after about 5 seconds it goes off and so does the LED on the sanguinololu - that seems like a bad sign to me. I haven't done much debug on this figuring that I'd get the base sanguinololu working first and do some more short testing on the panelolu2 board before trying again.
But I'm wondering if the firmware being configured for the panelolu2 is getting stuck somewhere in boot-up because I don't have that plugged in? Should I reconfigure the firmware to not have that board and see if that helps? (any tips on getting the panelolu2 debugged?).
