TMS320F28P650DK: CLA can not debug on-line

Steven Xu

Part Number: TMS320F28P650DK
Other Parts Discussed in Thread: LAUNCHXL-F28P65X, CCSTUDIO

Hi， Experts

My project is running on LAUNCHXL-F28P65X board, and plan to use CPU01 + CLA work for control function, and CPU02 work for communication function. Now CPU01.out file and CPU02.out file can burn to flash and work well, but if I add CLA Module in project, The CLA can not burn and work.

the Ram address locate in RAMLS8_CLA and RAMLS9_CLA. and the configuration of CMD is below:

the code of CLA initialization function is below:

Only Cla1task1 is triggered by EPWM1INT. and other tasks is disable. the EPWM1 can work well. and enable EPWM1INT after EPWM initialization.

Also the button of Type2 CLA is On in Option bar.

the Debug Option settings as below screenshot:

then, I click the Debug Button, and after Flash erase and program finished. the CCS debug GUI will display the CLA is disconnect.

And then if I click the connect target button and load the CPU01.out file, the Error will report: "CPU1_CLA1: Trouble Setting Breakpoint with the Action "Finish Auto Run" at 0x90f9f: (Error -1209 @ 0x90F9F) Device does not support software breakpoints. If available, use a hardware breakpoint. (Emulation package 9.12.0.00150)"

While if I run the CPU01 and CPU02 first and then load the CPU01.out file, the error will report again.

So, can you give me some advice about this issue.

For CLA select load the symbols only from the load menu.

Also for this device, there is a CLA debug issue that is currently being investigated. Refer to this thread for more information and a tracking link:

Hi Steven,

This issue is caused due to an error in the device xml file within CCS. We will get it fixed in the next release of CCS.

In the meantime, you can use the attached xml file (f28p650dk9.xml) and place it in <CCSInstallDir>\ccs\ccs_base\common\targetdb\devices.

/cfs-file/__key/communityserver-discussions-components-files/171/f28p650dk9.xml

After copying the file, restart CCS using command prompt with following command to clean the cache.

C:\ti\ccs1250\ccs\eclipse>ccstudio.exe -clean

Also , you need to use the updated attached ccxml file for launching the debug session.

/cfs-file/__key/communityserver-discussions-components-files/171/TMS320F28P650DK9.ccxml

Let us know if this resolves the issue

Best Regards

Siddharth

Hi， Siddharth

I update the lastest version CCS, and replace the f28p650dk9.xml and TMS320F28P650DK9.ccxml as well. also open the CCS GUI according the command prompt with "C:\ti\ccs1250\ccs\eclipse>ccstudio.exe -clean".

after I import the project and debug. a debug error will report as below screenshot:

So ,what can i do next?

Hi Steven,

Sorry for that , forgot to send the updated module xmls files .

Pls extract the files in the attached zip folder to C:\ti\ccs1250\ccs\ccs_base\common\targetdb\Modules\C2000.

The device xml was updated to reference these files and since these are missing, it is throwing an error.

Hi, Siddharth

if I click connect CLA button and load CPU01.out file into CLA, it will report this error.

is some thing wrong with my operation?

Hi,

You have to load program on the C28x core and load symbols to the CLA core.

Pls refer the following link

Hi, Siddharth

After I select Load symbols to load CPU01.out file to the CLA core, nothing changed, and it also showed "no symbols are defined'.

I think CLA can not be load symbols.

Hi,

This is expected behavior. The C28x code configures the CLA , during this configuration, it specifies the trigger source (peripheral interrupt / Software trigger/ another CLA task) which will trigger the CLA tasks.

If you run the code on C28x core and it triggers the CLA task, you can see that CLA is executing the task. You can also add "__mdebugstop();" statement in the CLA task to halt it.

Best Regards

Hi, Siddharth

Thanks for your support, the cla tsak can be trigger and enter, your help has greatly short my program schedule.

but cla task still runs strange, after I run CPU01 core, the CLA core will stop in cla task1 and cannot free auto run next. and I have to click on green resume button again and again to push the cla run. The disassembly GUI in below screenshot. can you give me some solution?
