Tool/software: Code Composer Studio

Dear Sir/Madam,

I facing issue with DSP Memory Limit. I had tried with two different DSP processor as mention in below.(i.e C674X and C6745).

Code Composer Studio  Version: 5.5.0.00077

C674x

TMS320C64X+_0: GEL Output: Loading Simulation Data

TMS320C64X+_0: Warning:  The application is using 64 MB of DSP memory. Verify               application memory usage.

C6745

I tried to add in the following filei.e(tisim_c674x_ca.cfg)

MODULE C674X;
MEM_USAGE_LIMIT 100;
END C674X;
After above changes made also not working.
if I load gel file with less memory , it's working but if I need with more memory usage the above memory issue was occurring.
could you please help me out this problem

    This is for the C674x CPU cycle accurate sim? If so, \ccsv5\ccs_base\simulation\bin\configurations\tisim_c674x_ca.cfg is the correct file to modify. 

    For the C6745 simulator, the file would be \ccsv5\ccs_base\simulation\unsup\cp_2011_12\bin\configurations\tisim_c6745_ca.cfg.

    If those files are being modified, then it looks like you are following the correct steps. Unfortunately, the simulators have been completely unsupported for some time so there is not much more help we can provide on this.

    Hi Ki,

    Thank for your prompt response. I tried both the cases i.e (C674X CPU cycle accurate and C6745 CPU cycle accurate. I was getting the same error which was mention above.

    May I know the editing the below code is correct.

    For the C6745 simulator, the file would be \ccsv5\ccs_base\simulation\unsup\cp_2011_12\bin\configurations\tisim_c6745_ca.cfg.

    Added at starting line of code in this file tisim_c6745_ca.cfg

    MODULE C6745;
        MEM_USAGE_LIMIT 100;
    END C6745;

    For the C674X simulator \ccsv5\ccs_base\simulation\bin\configurations\tisim_c674x_ca.cfg is the correct file to modify. 

    Added at starting line of code in this file tisim_c674x_ca.cfg

    MODULE C674X;
         MEM_USAGE_LIMIT 100;
    END C674X;

    Is there any alternate solution to resolve this issue. could you please help me out.

    Thanking you,

    Lakshmikanth.

    Hi Ki,

    The workspace in use for the simulator is actually working as expected in other colleague system where as in my system is not working. This is so strange  behavior.

    if there is an issue it should be an issue in everything right. could you please help me out of this issue.

    Unfortunately, we have stopped supporting simulators a long time ago. Our policy regarding them is that if you want to use them, they are available "as-is" and "use at your own risk" with NO support available. If you have a working environment on your colleague's system, all I can offer is to carefully diff the environments and see what the differences are (is your colleague using the same out file? is the ccxml file the same? did he do the same modifications on the same cfg files? etc). Otherwise I cannot offer much more insight

    Hi Ki,

    Thank you for your response. I will go to through working environment on the colleague system and I will try to do the modification if I need to the change anything.

    Hi Ki,

    Actually I have made change in the  the following file i.e(tisim_c674x_ca.cfg)

    MODULE C64xplus;

    MEM_USAGE_LIMIT 1000;

    END C64xplus;

    After doing the above modification, the issue is resolved. it's not hanged and No issue. Thank you for your support.
