CODECOMPOSER: Adding a data watchpoint in CCS's debugger and changing compilation optimization

Hello TI experts,

I am working with the HECR demo for the AWR2944EVM. Currently I am debugging the trackers code within CCS12.

I have modified the demo to stream custom debugging TLVs and I have found out that the key problem is that the tracks don't get spawned because the if statement inside of gtrack_moduleAllocate inside gtrack_module.c is never true:

if (fabsf(mCurrent.vector.doppler - mCenter.vector.doppler) < inst->params.allocationParams.maxVelThre)

This seems to be because inst->params is populated with incorrect data despite the settings in chirp_design_HECR.h. To investigate this further I have several questions.

So that is why I want to ask you:

How to set a data watchpoint for inst->params.allocationParams , so that I can analyze all reads/writes to this variables address during program execution?
How can I change the compilers optimization settings so that it includes more debugging flags (, i.e. form -O3to -O0)?

Regards,
Mark

You can set a data watchpoint on an expression or a direct address: https://software-dl.ti.com/ccs/esd/documents/users_guide_ccs/ccs_debug-main.html#watchpoints. Depending on the cpu you can specify to trigger on a read, write, or both.

For the best debug experience you would want optimization off. For the ARM clang compiler, that would be "0". For the C6x compiler, that would be "off". As you turn on optimization, it will start impacting source level debug. Something like -O3 would have high impact, making source debug very difficult:

I just realized you are using the older CCS 12.x version. Please refer to this link instead: software-dl.ti.com/ccs/esd/documents/users_guide_12.8.0/ccs_debug-main.html#watchpoints

Thanks

Hello Ki,

thank you for your response. As suggested, I did follow the manuals instructions but I am unable to set activate the watchpoint set at my variable of interest. I keep getting a warning: ' "numClusterEvents" does not resolve to an address'. Please take a look:

Concerning the optimization, the provided link discusses the overall principle and tradeoffs - that I do know. What I would like to get is guidance how to change the optimization for the whole project in CCS.

Thank you for your help.
Best regards,
Mark

You will need to enter an expression that resolves to an address. Or simply specify the exact address.

Check the compiler build properties:
