So, I tried again before sending it back. I flashed to 4.3, didnt work. Flashed back to 4.2.2 and still doesnt work.
DfuSe demonstrator says the 4.2.2.dfu firmware is onboard, confirmed with MFDeploy.
Heres the problem.
I disconnect and reconnect the cable and try writing my program to the N+2. Correct framework and target device selected. NetduinoPlus2_Netduino is showing. Get an error, unable to communicate with device USB:Netduino. Disconnecting and reconnecting doesnt work.
I have a N1 which works perfectly, same program runs on it solid.
After trying to write from VS2012, I go back to MFDeploy, NetduinoPlus2_Netduino shows up but when i go Target>Device Capabilities I just get a Not Supported in the memo box.
