CCS/TMS320C6711D: memory browser did not show values in memory

Part Number: TMS320C6711D

Tool/software: Code Composer Studio

Hi,

I use the CCS6.2 and tried an old project with the TSM320C6711D DSP and use the DSK6713 platform settings. Even the memory map of code composer is set correctly I could not view any memory in the memory browser, as example 0x80000000. The same project  ans memory settings running under CCS 5.4 works fine. Whats'S wrong?

kind regrds Gerhard

  • Hi Gerhard,
    Can you explain what you mean about not being able to view any memory? Are you saying that the memory is not accessible and you get an error? Or do you see invalid data? A screenshot would be helpful.

    Thanks

    Hi Ki,

    sorry for the unclear description, there are only question marks in the memory browser. Even I get a pop up window after using the memory view command in the context menue of an expression. The pop up stated that no access to memory is allowed. Hope this clearify my problem.

    If I tried the disassembler view I could access the memory area and see the code. This shows me that memory access is available, but not for data view.

    Here some example of my memory setting:

    GEL_MapAdd(0x00000000, 0, 0x00030000, 1, 1); // Internal RAM (L2) mem

    GEL_MapAddStr(0x80000000, 0, 0x01000000, "R|W|AS4" , 0);

    But both ares are only shown as question marks in the memory browser.

    Kind regards Gerhard

  • In reply to Gerhard Glaeser:

    The question marks indicate that the debugger memory map allowed debugger read access to the target memory but encountered an error when trying to access it (if the debugger memory map was blocking access, you would see a dash instead). Normally I would say that the location is either invalid memory or not initialized properly (common when working with external SDRAM) but you said that the same address is readable by the disassembly view. This is strange and I can't reproduce this. Are you able to reproduce this issue before you load the program? Where you just connect to the board and then see if you can view memory at the problem locations?

    Thanks
    ki

    Hi Ki,

    I did what you promise, disconnet the debugger, reset the board, connet the debugger => same behaviour, only questions marks are shown but in the disassembler view I could see the code correct. Strange behaviour. Any idea where I could see whats goes wrong?
    Kind regards Gerhard

    Can you provide a screenshot of CCS with both the memory view and disassembly view open side-by-side on the same address?

    Thanks

    This is strange and I don't have an answer yet. Can you send to me the GEL file that you are using?

    Thanks

    I have exactly the same problem. Windows 10 (64 bit). CCS 6.2.00050.

    My memory windows at known good addresses on a DSK6713 all show "?". I can set an expression, and it reads and writes properly in the expression window. 

    I have a standard DSK6713.gel. 

    Did an answer turn up?
