F2837xD EMIF to Sitara comm

Other Parts Discussed in Thread: AM3359

Is it any way to setup a communication between between F2837xD EMIF (as master) and AM3359 memory interface?

Thanks!

    I'm not very familiar with AM3359 so take that into consideration for my comments.

    Looking at the datasheet, it doesn't look to me like there is a native way for the two EMIFs to communicate directly.  My understanding is that EMIF is designed to be a master interface only.

    If you have a free PRU on AM3359, you might be able to implement an asynchronous slave memory interface using free pins and connect that to the F2837xD EMIF.

    Otherwise, you may have to resort to another common interface like USB, SPI, UART, CAN, etc.

    Indeed the EMIF or GPMC on Sitara AM3359 are also designed to be master, so I'm not sure if is something that can be done here.

    Implementing a slave EMIF on Sitara from bit banging is an interesting idea but really I'm not sure exactly what I have to do or if is possible. Maybe I should be posting this on Sitara forum, because this is mostly an AM3359 configuration ...

    Thanks for your insight!
