CCS/TMS320VC5510A: DSK 5510 SIMULATOR MEMORY MAP

Hello,

The debugger memory map is often configured by the GEL startup file. Are you using one? If you are, there should be a file listed under the "GEL files" folder in the left panel of your CCS IDE.

Note that these is no DSK 5510 Simulator. There is a C5510 Device Simulator which simulates the device itself. But it does not simulate the whole DSK.

In your screenshot, it looks like you are using the C5510 DSK HW target

Thanks

hello ki,

Thanks for the explanation.

yes,i am using C5510 DSK HW target board  and the file is listed under the "GEL files" folder which remain common for all project. I mean to say that i dont have to add it each time, its there by default.

I am confused about the fact that as the GEL startup file already there in simulator is configured for particular device c5510 then why i have to change it even if i am using same target device.

next considering the requirement that in order to solve data verification problem i have to change memory map configuration, i check help documentation of c5510 device simulator i found functions to define memory range but no information on how and for what memory part assign to different sections as while loading the data verification error pop up for address like:

.sysinit 0 of 284 at 0x20000

.rtdx_text 0 of 1732 at 0x2011c

.bios 0 of 10183 at 0x207e0

The memory map of target device c5510 is given in its data sheet.

following is the default gel file for reference:

/* The Startup() function is executed when the GEL file is loaded. */

StartUp()
{
    C5510_DSK_Init();
    C5510_DSK_EMIF_Init();
    GEL_TextOut("C5510_DSK GEL StartUp Complete.\n");
}

    C5510_CPU_Reset();
}

Hello,

Have anyone have idea as how to assign sections in memory map for c5510 device.

Thanks

Regards,

Sandhya
