Distinguish C6654/55/57

Hi ,

How to distinguish C6654/55/57?

We have checked JTAG ID, CSR, REVID regsiters, and find all of them are same.

Do you have any idea on this?

    Hi,
    I do not think keystone devices has unique identification register to find running DSP. 

    The below things may help you to implement,

    1. How about using the MAC Address(efused)? It's unique for each device. 

    2. How about using the speed of the DSPs (i.e. C6654 & C6657)? The C6654 operates between 750-850MHz and C6657 operates between (1-1.25GHz).

    3. How about dedicated 1MB L2 memory/core? Write and read back pattern on core 1 dedicated L2 using global address space. (C6654 has only 1 core whereas C6657 has 2 cores)

    4. How about 1MB MSMC memory? Write and read back pattern on MSMC memory using global address space. (C6654 has no MSMC memory whereas C6657 has 1MB shared)

    Thank you.
