AM5708: GPMC

Part Number: AM5708

Hi,

Does AM5708 GPMC can act as a slave. I am planning to implement a multi master parallel bus using AM5708 GPMC core, like QBUS. So I would like to know whether with DMA access one AM5708  could act as slave when other one act as Master

Regards

    Hi Athuljith,

    I don't see any issue with this, I am looping GPMC experts here for deeper insight. Please wait for their feedback,

    Athuljith,

    Can you share the specification for QBUS?  The main concerns I have with AM5708 GPMC acting as a slave is all the single direction I/Os we have.  For example, GPMC CS pin is output only and WAIT pin is input only, and other control signals like ADVn_ALE, DIR, OEn_REn, WEn, etc are all also driven by the module.

    Best Regards,
