Hi TI,

Hope you are doing well.

I want to know that UDMA resources I need to transmit and receive ethernet packet using MAIN domain UDMA and MCU domain UDMA.

Looking forward to hearing back from you.

    Hi,

    You need UDMA Tx channels, RX channels with Rx Flows mapping to CPSW PSIL Threads.
    Also, you need to Ring accelerators, Virtual Interrupts and Proxy.

    Please refer to Enet examples in PDK for UMDA init, channel open for Tx & Rx for more details.

    Best Regards,
