AM5718: How to make single port Ethernet to 4-port Ethernet in AM5718?

Dear Support Group,

I am looking for how to multiplex the 1port ethernet to 4-port ethernet in AM5718,

Regards.

    Wasim,

    Currently the SDK supports 3-port switch (host port + 2 external ports) across each of CPSW3G and the two PRU-ICSSM  subsystems. Each switch is independent, so while there are six external MAC ports on the AM5718 there is not a release supporting a 4- (for the two PRU-ICSSM interworking) or 6-port (aggregated across all ports).

    Can you confirm that you are looking for a fully-connected 4- (external) port switch?

    Best regards,

    Dave

    Wasim,

    Four independent MAC ports is supported directly. You mentioned RMII, however, and four RMII ports are not supported by the device. The CPSW3G supports two RGMII or RMII and each PRU-ICSS supports MII.

    The AM5718 IDK can be used for development. See https://www.ti.com/lit/pdf/sprui97 for details.

    The standard (4-portEthernet) configuration for the AM571x IDK EVM provides the following functionality:

    •  Two Gigabit (1000Mb) metallic ports connected via PHY/RGMII to the on-chip Ethernet switch

    •  Two 100Mb metallic ports connected via PHY/MII to the PRU-ICSS subsystems

    •  LCD panel output from Display Parallel Interface (DPI) Video Output1

    Reconfiguration through header shunt removal provides an alternate 6-port Ethernet configuration:

    •  Two Gigabit(1000Mb) metallic ports connected via PHY/RGMII to the on-chip Ethernet switch

    •  Four 100Mb metallic ports connected via PHY/MII to the PRU-ICSS subsystems

    Software support for the AM571x IDK EVM is provided within the Processor Software Development Kit (SDK) package. This includes both Linux and RTOS support. See http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_pru_icss_fw.html?highlight=dual%20mac#dual-emac-and-switch . 

    Best regards,

    Dave
