AM6442: To use GPMC0 for data tranfer between two AM6442 based processors at high speed

Part Number: AM6442

Can I use GPMC0 for data transfer between two AM6442 based processors at high speed?

Is it possible to configure GPMC in such way? Is ther any API built for this?

Or can we customize it for such use? Can we write drivers for such case?

We are in situation where we want to have high speed data transfer between two boards.

    Hello Manoj,

    GPMC is NOT recommended for inter-processor or inter-board communication – it's strictly for external memory devices (NAND, NOR, PSRAM).
    For high-speed data transfer between two AM64x-based boards, we need to explore the proper communication interfaces.
    Before I recommend the correct solution, I need to understand your requirements:
    Which cores on each AM64x?
    Expected data transfer speed:
    - 10 Mbps?
    - 100 Mbps ?

    Regards,

    Anil.
