I've a problem with setting a breakpoint on a specific line or code in the source file.

Other Parts Discussed in Thread: TMS320F28388D, TMS320F28335

Hi,

CCS : v11.1.0.00011
CGT : C2000 TI v21.6.0.LTS
Processor : TMS320F28388D
Area where the code runs : Internal RAM

I've a problem with setting a breakpoint on a specific line or code in the source file.

If I select a code or line by dragging the mouse and set a breakpoint through the shortcut menu by clicking the right mouse button, the breakpoint is not set normally.

However, if I set a breakpoint by calling the shortcut menu with the right mouse button in the Breakpoints tab and directly entering the address of a specific code, I can set the breakpoint normally.

I wonder what is causing this problem.
(Please refer to the video attached to this post.)

Thanks.

Hi,

What is the optimization being used in the project? Can you turn off the optimization and then try?

Please take a look at this thread for similar issue:

Thanks & Regards,

Hi,

I did not set the compiler's optimization options, and full symbolic debug is also applied to project.
And, since the program is being executed in the internal RAM area of the chip, although a S/W breakpoint is used, but, the breakpoint is not normally set and the program execution is not stopped at that location.

Another strange thing is that in the same PC, CCS, and debugger environment, the breakpoint setting and operation are normal on the TMS320F28335 chip and related projects.

The same problem is observed even if I clean the Workspace or change it to a different path.

I would like to know what is causing this problem.

Thanks.

Sang,

Do you have a simple trim-down project which can produce the issue and can be shared? Then we can take a look at the project.

Thanks & Regards,

Santosh

Sang-il,

Santosh is currently out of the office for this week. I will see if I can get this re-assigned to another engineer. Please give us until Wednesday for our next reply.

Best,

Matthew

Sang-il,

Thank you for the test case. I will try it this afternoon and keep you posted.

I believe the issue is the square bracket characters in both the project name, project folder, and the one source file. There are known issues with non-alphanumeric characters:

https://e2e.ti.com/support/tools/code-composer-studio-group/ccs/f/code-composer-studio-forum/740719/faq-ccs-why-do-i-need-to-avoid-non-alphanumeric-unicode-characters-in-my-paths?tisearch=e2e-sitesearch&keymatch=faq%3Atrue

I was able to reproduce the issue. Then I renamed everything to remove the square bracket characters "[" and "]" and rebuilt the program. Then when Ioaded the porgram and tried to set the same breakpoints, it worked fine.

I attached my modified project. Can you give it a try?

Awesome,

I've verified the project you provided.
The breakpoints are set up and working properly.

Thanks for your quick and friendly response.
