TMS320F28379D: Debugging Dependencies with XDS110 Debug Probe

Tool/software:

Dear TI,

Hello,

I am trying to debug a project using the XDS110 Debug Probe.

My project depends on several folders (libdri, ASW, DCL). In the main project, the .out file is successfully generated, and I can set breakpoints in the files belonging to this project. However, when I try to set a breakpoint in the dependent folders, XDS110 throws an exception and prompts me to load symbols.

The issue is that when I compile, only one .out file is generated for the main project, and there are no separate .out files for the dependency folders. This prevents me from loading symbols for those files.

Could you please help me debug files that come from dependency folders?

Project structure:

Dependency 1
Dependency 2
Dependency 3
Main Project (depends on 1, 2, 3)
- Generates main_outfile.out

Thank you in advance for your support!

Best regards,

Hi,

Are you loading your program to flash?

Do you only experience this problem after a power cycle?

Loading symbols is just telling CCS which program you have loaded onto your device. Does loading the symbols fix the issue?

Thanks,

Ben Collier

Hello Benjamin,

Yes i am loading to flash.

No, when ever i need to put a break point in the .c dependencies files, the break point is disabled.

I could not load the dependencies out file, there is no out file generated in the dependencies files.

Hi,

What is your file search path for the C2000 Linker (Project Properties > CCS Build > C2000 Linker > File Search Path)?
Do you have full symbolic debug enabled (-g flag) for your debugging model (Project Properties > CCS Build > C2000 Compiler > Advanced Options > Advanced Debug Options)?
Also, please refer to this guide (for CCS v20, if you want to try on there): https://software-dl.ti.com/ccs/esd/documents/users_guide/ccs_debug-main.html#debugging-library-code

Best,

Matt

Hi Matt,

I am using CCS.
In the linker section, the include paths used are .lib files for each dependency.

I have checked that the -g flag is enabled for all dependencies.

In the image below, I can step through the code, but I am unable to add a new breakpoint.
This issue occurs in the dependency file (os.c).

Hi,

This error most commonly appears when attempting to set a hardware breakpoint, although it can appear when attempting to enable other "jobs" (debug operations) that may use an AET (or AET-like) resource.

Are you running this project in Flash? A software breakpoint is implemented as an opcode replacement in RAM, and hence does not use a resource. There is no (theoretical) limit to the number of software breakpoints that can be set, while only ~2 hardware breakpoints can be set.

Please refer to this document for troubleshooting resources: https://software-dl.ti.com/ccs/esd/documents/troubleshooting_no-aet-resources.html

Best,

Matt
