Unable to debug TWR-S08PT60 after programming.

[ericbryan]

Code setup the IIC in slave mode and then issued a STOP to wait for an interrupt.   After programming with this code the debugger is unable to connect.  I suspect that the debugger is unable to interact while the processor is stopped?  I guess I could stimulate the IIC and see if the debugger can break in then.  Anyone else have this issue and know a solution?  I've ordered a spare board just to make sure the project keeps moving for now.

Hi Eric

yes, when the MCU is in stop is hard to enter to debug or program again the board, are you using the open BDM on the TWR?

If you have a cyclone pro you can use it to reprogram the board using the BDM header instead of the USB OSBDM.

If you do not have a Cyclone you need to force to reset the MCU to enter to debug mode and reprogram it.

I believe you can do that using the BDM header of the board and put in low the reset and try to make the comunication.

I hope this helps
