help on using instrumentation load modules on sysBios 6.34.4.22 with C6657 DSP

Hi Weichun,

Sorry for the delayed response.  

Can you elaborate on what you mean by: "I could not get the definition of structure Load_Stat, nor can I link function Load_getGlobalHwiLoad();"?

Are you getting this error during build time?  Is there an error message you are receiving?

Thanks,

Hi, Emmanuel,

Thanks for updating.

The structure Load_stat is not defined as part of the sysBios header, so I temporarily defined it as a struct of two int32. Then at linking, the link failed and I got the link error Load_getGlobalHwiLoad is not found.

It seems that I have not include the module appropriately even though the cfg file I modified did not get any complain from build process.

Thanks

Weichun

Hi Weichun,

You need to include ti/sysbios/utils/Load.h in your .c file.

Best regards,

Hi, Janet,

thanks a lot. But I also got linking problem (could not find symbol Load_calculateLoad nor Load_getGlobalHwiLoad to link), is there an additional library which I have to include?

thanks

Weichun

Did you remove your temporary definition of Load_Stat?

thank you so much. It works.

Does it mean that the include file change the sysBios library built or the build process internally added more libraries during the link stage?

It just seems a little bit mysterious to me that a header file change during compilation stage would impact if the function exist during link stage. It would be great if you could shed some light on it.

thanks

Weichun
