Debugging with MPLAB6.3 and ICD2

hhoebel · Guest

I'm wondering how i can debug a project using more than one source-file. I've using a project with several files which i all include in the main-souce-file due to that missing linker.
My problem is that MPLAB can't set breakpoints in the source-code of the included files. I get always a "breakpoint can't be resolved". Any idea how i can get around this?

regards,

Heiko Hoebel

I have the same problem. Can't resolve breakpoints. I have PCWH 3.174 and MPLAB 6.3. I have sometimes been able to set breakpoints but usually not. I can't figure out what the sequence was that made it work. It's very frustrating to continue to have these problems considering how long both CCS and MPLAB have been around.

I have also got this problem, and have emailed CCS support!

I may have figured this out...

From the PICC workspace, open your main source file, then select tools->MPLAB

Open the new MPLAB project file that appears on your source directory.

Go to Project->Build Options->

Select the main c source file (not the global project setting)

Select list file as normal CCS, debug file as COFF. Press OK.

Make sure that compile for use with ICD debugger is checked.

It should now be able to resolve the breakpoints.

I used the same settings as tobyboreham and was still having trouble.

I kept his settings and instead of doing a "build all" in MPLAB i right clicked on my main program file in the project tree and chose compile. Now it's setting breakpoints in any file I include from my main file. Using "build all" which has the same command line as compile Question

never works for me.. Could anybody else verify this?

I had this reply from CCS tech support:

"We have confirmed that the coff file is correct and it is an MPLAB IDE issue that the breakpoints are not validated and allowed on all source lines. You would need to contact Microchip about it.

Thanks CCS Tech Support"

this works for me:
set a break point on the main source file that calls a function from the include source file.

once it halt at that break point press F7 (single step)

now the pointer will be on the include source file then set the break point any where within that file

I called Microchip support about this problem. They told me to use the use the disassembly window (VIEW-> disassembly) and set breakpoint there. This works very well. Also, I switched to MPLAB 6.31 which is much better than 6.30.

Debugger -> COFF file has made the trick for me

until then the disassembly window just showed spurious ASM code and I was not able to trace the code but in the program window.

half day wasted, I've been lucky. Thanks for the input.

Experienced the problem of breakpoints refusing to work at all in MPLAB. Discovered that there seems to be a path length issue. I'd previously discovered this with MPLAB anyway, but using CCS seems to be be tighter. Moved the project directory higher up the drive and breakpoints started working.
