No Locals + Debugger skips breakpoints
PostPosted: Wed Jul 12, 2006 8:36 am     Reply with quote
Hi, Im almost new to CCS compiler.
Tring to debug an application on 18F2550 via ICD2, I do not understand 2 things:
- Cannot see locals inside functions- Locals window is empty
- Debugger never hits breakpoins exactly, either skips into next commands or does not stop at all.
- Sometimes debugger complains about unknown breakpoints - DId I miss a setting that makes the debugger use new debug information each time I press F10 ?

Any help invited. What can I do for you in exchange ?

The ICD2 debugger has a well documented bug. It stops one instruction later than it should. You could add a NOP immediately following the code segment you want the debugger to halt on.

This is a quirk that occurs when you set a break point and subsequently modify the code. When you attempt to run the code it is not able to determine how the break point maps to the modified code. I call this feature a bug.

So all up - two strikes.
