It sounds as if the memory interface on the device is not being
configured correctly when CCS starts up and you connect to the device.
This is usually handled by the GEL file that you specify in CCS setup.
What GEL file are you using? I recommend that you use the attached GEL
file. Please note that GEL files for CCS v2.x and v3.x are different
although the names might be the same. If the GEL file you are using has
the same name, I am wondering if the contents of the file are actually
the same. 

Also, have you configure CCS to debug both ARM and DSP or just the ARM?
In CCS setup there are different configuration that can be selected
where you can just emulate the ARM or both ARM and DSP. If you have
configured CCS to connect to both ARM and DSP, I recommend that when you
start up CCS and the "Parallel Debug Manager" starts-up, you first
connect to the ARM and then connect to the DSP. I have found that trying
to connect to both does not work reliably. However, this maybe expected
because the ARM needs to release the DSP from reset before you can
connect to the DSP.

This should not be necessary.

Again, sounds as if the device is not being initialised correctly when
CCS starts-up and you connect to the device.
