AM6421: RGMII Interface for EtherCAT supported by hardware and software?

Part Number: AM6421

Hi TI,

Is RGMII Interface supported for EtherCAT by hardware and software? According to AM64xx datasheet, and TRM, the Industrial Subsystem supports MII and RGMII by hardware. Also the PHY which is used in AM64 EVM does support both MII and RGMII. However, when looking up the example applications for EtherCAT in mcu_plus_sdk_am64x_08_03_00_18/examples/industrial_comms, the corresponding PinMux file (ethercat_slave_demo/simple/am64x-evm/r5fss0-0_freertos/example.syscfg) ist set to MII mode for EtherCAT.

Can you please confirm, that RGMII is supported by hardware as well as by software?

Thanks for your help and best regards,
