I've built up a new PCB with an SX18 on it. It will run simple programs just fine. But, if I load one of these programs with the debugger, the debugger always comes up in the "running" state and hence not able to do any actual debugging. The reset button is does not stop it, and the "stop" button is grayed out. I've left room at the beginning of the code for debugger. I've tried this on several boards with same result.
I have a couple of older designs with SX28 parts and they work just fine with the debugger, so I'm confident that my software environment is OK.
Any ideas out there?
