problems with memory map on eZdsp with TMS320F28335

 Hi,

i immigrate a program from F2812 to F28335 DSP.

my problem is, if i write the program to the dsp i get a failure like:

 "Data varification failed at address 0x200000. Please verify target memory and memory map."

can anybody help me?

best regards Marco

 my command file is:

     0x200000 is part of the XINTF and is zone 7. 

    Two thoughts:

    * On the ezdsp I believe there is external ram connected to zone 6 only (address 0x100000).  I suggest double checking the documentation on this.

    * Otherwise, you will need to enable the XINTF clock and configure the GPIO MUX registers for XINTF funcionality before you can load to XINTF.  There should be a funciton called XINTF_Enable() in the .gel file that will do this for you.

     Hi,

    thank you for this idea, with the gel function the programm sections will write to ZONE7A on the F28335.

    best regards

    I'm experiencing something similar.

    I'm running my program from the external SRAM on the ezDsp28335 and find that I must execute the XINTF enable GEL file before each download, even if I didn't power down the ezDsp.

    I was wondering if anyone knows of a way to get the GEL to execute automatically before each download.

    Make sure you have the F28335.gel loaded in the CCS project.  This GEL file has the following function that executes automatically before the program is loaded:

    OnPreFileLoaded()
    {
        XINTF_Enable();
        if (TxtOutCtl==0)
        {
         GEL_TextOut("\nNOTES:\nGel will enable XINTFx16 during Debug only.\nEnable XINTF in code prior to use.");
         GEL_TextOut("\nFPU Registers can be found via GEL->Watch FPU Registers.");
      TxtOutCtl=1;
        }
    }

    Thanks, that worked great!
