AM5726: The Max number of Ethernet ports

Part Number: AM5726

Hello,
How many Ethernet ports are handled by AM5726 SR2.0 at the same time?
Or, is there a material to confirm that?

Please assume all the ports are used for EtherCAT master or slave.


From SPRABX8E.pdf, p10, we see six ports are not supported.

Then, how many ports are good?


The TI PinMux passed the following combinations:
(#GMAC_ports: #PRU_Ports) = (2:2), (1:3), (0:4).  The following example is (1:3):

But a remaining concern would be an internal bandwidth.

  • Hideaki,

    AM5726 supports
    - 2-Port 1Gb Switch
    - 4-Port 10/100 PRU EMAC

    Due to pinmux as you indicated, it can maxim support 4 ports in parallel: 2-port 1GbSwitch and 2 port 10/100 PRU EMAC, or 4 port 10/100 PRU EMAC only.

    EtherCAT slave is only supported on PRU EMAC (instance 0 or 1).

    EtherCAT master is supported on both Gb Switch and PRU EMAC (instance 0 or 1).
