Just encountered a strange problem. I took a project from 2.2 SP1 and imported it into 3.0. I can compile and execute the code just fine in Debug mode. However, when the code is compiled in release mode, it fails to execute. In other words, the processor appears to hang. This is on a CY8C4125.
I did not have this issue in 2.2 SP1.
It's a bit difficult to determine why the program has failed because all communications cease. The chip is a CY8C4125.
