Other Parts Discussed in Thread: AM3354

Hi, 

I want to connect two AM3354. Which interface should be the best?

The interface speed should be 100MHz.

    Can you please elaborate? What exactly is your use case? Data transfer between the two SoCs or something else?

    The only interfaces in AM335x devices that fast are GPMC & USB. But you cannot use GPMC interface to communicate between two Sitara devices, so if you need to transfer data between the two devices the USB is probably the best option.

    The Ethernet Subsystem is another option.

    Not sure of the protocol overhead of USB .vs. Ethernet communication.

    Hi, Yordan,

    It is telecom equipment. One AM335x is main chip. Another AM335x will be backup.

    I need two AM335X connect in high speed interface.

    It looks GPMC is not suitable. USB and Ethernet is not a option as we need for other use.

    Hi,

    I'm afraid that there aren't other interfaces in AM335x devices, which can be used, except for the CAN, but it will be slow for your application. Maybe some external logic could be applied (wi-fi module + mmc controller or something else).
    Or you can contact your local fae to request information about the latest AM devices, they could be of use to you.

    Best Regards,
