Been about 14 months since I've used my QSB, and I know I left it in a good working state. Had it booting from an NFS drive.
I have a project in mind, so powered it up: 1st hooked up serial to get into the monitor.
Turned power on, and the LED's transitioned properly (seems that a couple of them turned blue), but didn't get any serial. Fiddled around a bit with my serial connection, trying several things (null modem, different baud, even a different machine). Still no serial.
At some point the board quit powering up when I hit the power button: meaning that All the Led's did not come on. (I got no blue LED's)
So right now LED's are stuck like this:
5V led is green
FLT led is red
And that's pretty much it: they NEVER transition to anything else. Power button doesn't change anything, reset button doesn't change anything.
Have tried 2 different power supplies: the one that came with the unit, and a nice bench-supply (an old analog Power Supply) from HP. The HP shows the unit getting about .17 amps when power is enabled, and no change whatsoever when I hit the power button.
I don't have a DVM and I don't have JTAG (but have a flyswatter-2) on order. So right now I have no ability to probe or debug.
