C6655 and C6657

we are working on a system on which either C6655 or C6657 could be populated. We plan to use the same dsp code for both C6655 and C6657.

Is there a register such as Rev/version we can read from DSP itself so that we can determine the dsp the code is running on is C6655 or C6657?

thanks

    No, there's not a register for this.  But you could attempt to write to and read from the Global L2 Address over CorePac1.  If you read back the value you wrote to, then you know there is a CorePac1 w/ valid L2 memory space and it's a C6657.  If not, then it's not there and the device would be a C6655.
