unable to load program on C6701 DSP

I have the XDS510 USB connected to the JTAG of a C6701 DSP.   I am getting the following error from CCS 3.3 when I try to load my program. " Data verification failed at adress 0x0.  Please verify target memory and memory map".  Sort of vague as to what the error might be, but I thought I would ask and see if someone here has gotten this before, I might have forgotten a step here.  It looks like CCS is trying to load my program data but does something wrong right away.  Thanks mike

    Hi Michael,

    It sounds like you may have the wrong memory map configured. There are two different maps as can be seen on page 8 of the Boot Modes and Configuration Reference Guide.

    The error you are seeing means that whenever CCS attempted to write to an address (in this case 0x0), the read-back did not match the expected value. This is most common whenever an external memory is not correctly configured prior to the load, but on a device like the C6701 where the address can change between internal and external memory my best guess is that either the EMIF CS0 is not correctly configured or you are in Map 0 when expecting Map 1.
