Data Verification failed at address 0xFFFF00 in CCS v 3.3

Hi 

I am trying to load my program into a custom board having C5510 DSP (using XDS 510USB emulator ). I am able to load other programs in the DSP and the pgm is running in Simulator.

On loading ,  I am getting the error


Data Verification failed at address 0xFFFF00. Please verify target memory and memory map.

My .cmd file is pasted below. Can you please tell me what the problem is????

Regards  -  Sunil

    Sunil,

    If you know you have an external memory device at this address, then check the status of the MPNMC bit in your device. Section 3.1 of the VC5510 datasheet says this device comes out of reset in MC mode, which places the ROM Bootloader code at address 0xFFFF00 (and therefore the .vectors section cannot be written). Setting this bit to MP mode will only work if you know you have an external memory device on the board. 

    The section vectors is required to set the interrupt vectors in your system. You can debug your code using CCS and do not necessarily need to set the interrupt vector table at this time. However, if you have other interrupt vectors and your board does not have an external memory device at the address above, you will need to relocate the interrupt vector table. Section 3.5 of the VC5510 datasheet has references on how to do it.

    Additional details about the boot process can be found in the bootloader documentation.

    Hope this helps,

    Rafael
