TM4C1237D5PZ Error while debugging

Saul Espinosa

I{m developing something for USB Bulk, but I took the Launch Pad project example and just replaced everything with my code (It's really hard to start a project if you are not using launch pad examples), everything works fine with the change from from TM4C123H6 to TM4C1237D5.

Now I need to debug to parse some data, but when I'm reaching the breakpoint, CCS stops in other instruction, even opens other files and sometimes opens an error window saying that there is nothing in a specific address. Seems like the debugger is still taking addresses for previous Micro.

Is there any configuration file or parameter to change to avoid my current issue for debugging?

Thanks

Hi Saul,

Those two devices have different flash size and SRAM size. Please check the CMD file to make sure the memory range is correct.

Hello QJ,

I actually changed the .CMD file to adjust memory start address and size. My code is running according to the desired behavior, but I can't debug correctly. That's slowing down my development since I need to verify "manually" the new lines I'm writing.

Do you want my project zipped in a file?

Thanks

Saul

Hello Saul,

Change the optimization level from 2 to "off" in the build settings. That will help fix the issue of the debugger stopping on the incorrect line.

Hi Amit,

I changed the parameters, currently is stopping at a different address but not matching with my breakpoint. Is anything else to do at deeper level, this occurred when I changed the micro only.

Hello Saul,

Can you show a snapshot of single breakpoint being set and the code stopping at some other location?

I placed a breakpoint in my RLY_API.c and it opens other c file.

I don't want to have same issue with release session by having wrong .bin code

I think you will save yourself a lot of pain/labour when your scrap this project, and set it up anew, for the proper MCU.
I have made similar experiences with Eclipse-based toolchains in the past ...

Hello Saul,

Worth a try

1. Make sure all libraries that are being used are compiled with NO optimization
2. Clean and Rebuild the project instead of a simple build

Thanks for your response, actually I created a project with the proper MCU, but I'm having same result.

I don't know if CCS6 in a free version is only supporting Launch Pad Micro.

I still cannot debug
