I have addet to my Panda board a serial interface in order to use the USB-interface for program driven interaction with the PC. All works fine and debugging is as usual. But as soon as I added the GHIElectronics.NETMF.hardware reference and want to debug the program, the same sequence as usual comes up(sucessfully), but I’m not in the debug mode and can instead start a new debug run with F5. I have reduced the setup (using only the FEZ-Panda Project and adding the reference) and the error occurence can be reproduced. Any explanations?
