The code in my program worked great until I added an 'If(!Ethernet.IsCableconnected) statement to the code. After that, I got errors even though the program built ok. Is this a firmware corruption or yet another limitation of the Panda II/Wiznet5100?
Here is my error:
Resolving.
Link failure: some assembly references cannot be resolved!!
