What socket do you have the Shield Base connected to?
Have you tried reseating the IDC cable to ensure that it's connected on both ends?
Do you have any other modules connected to your Netduino Go mainboard?
Do you have anything plugged into your Shield Base?
A few more details? ;^)
plugged into socket 5, which is the default socket for the app. No other modules plugged in, nothing plugged into Shield Base.
cables... hmmm. Hadn't try fiddling with them -
damn! it's working now. where did I put that cable down...
hardware 101... you'd think I'd learn - of course, it's been almost 30 years since I last played seriously with actual hardware...
The funny thing is that I'd tried this last night, and was getting back 0x80, instead of 0x00... I DID unplug / replug the shield base between at least once.
Ok - now I take it I have to remove the shield base and load a different program if I don't want to reflash every time I plug the Go! into USB...
