Hi,
(PIC18f87J50 , ICD3 ,CCS 5.080)
What I have..
With the debugger attached (in debug mode) and running the program it is working.
LED's are flashing LCD is used etc...
Switching to release and use the ICD3 as a programmer then the program doesn't run any more...
I switched the clock.. used the innternal etc..
enabled fuses .. disabled fuses but no luck..
anybody an idea???
Best regards,
Jody |

| I don't know what environment you are using. MPLABX? There are some options to hold a device in reset. Maybe that is a problem? I never had a problem with that, but some here have said that if you leave #device ICD = TRUE or #fuses debug (don't know which) in your code, the program doesn't run. |
