Code Composer 4.2.4 - can't set multiple breakpoints, C28xx: Breakpoint Manager: Error programming AET Job

Other Parts Discussed in Thread: TMS320F2812

Hello,

I am using Code Composer Studio 4.2.4 with the XDS510 USB emulator and TMS320F2812 eZdSP board. I am unable to add more than one HW breakpoint in my code. When I try to add a second breakpoint, I get the following error:

C28xx: Breakpoint Manager: Error programming AET Job: This task cannot be accomplished with the existing AET resources.

I found a suggestion in similar threads to uncheck the "Enable CIO function use (requires setting a breakpoint)" option in the Generic Debugger Options menu. This has not resolved my problem. I have tried manually setting the breakpoints, and I have also tried using a GEL file to set the breakpoints (via the GEL_AddOutputFile() and GEL_AddInputFile() commands), but neither way has worked.

Are there any additional settings I can change that will allow me to set 2 HW breakpoints?

    That setting (unchecking "Enable CIO function use") should allow you to set 2 hardware breakpoints. Do you have any other watchpoints or profile clock enabled that might be using up hardware resources?

    The other possibility is if you are using DSP/BIOS. In that case, one breakpoint would be used by default by the BIOS app. Please see this related thread for more information on that in case you are working with BIOS.

    Hi Aarti, thanks for your response. I am not using DSP/BIOS, the profile clock, or other watchpoints. However, I was able to get a second HW breakpoint working. I created a new project and recompiled and re-loaded my code and the second HW breakpoint worked (even with "Enable CIO function use" checked). Thanks for the assistance.
