Hi,

We are planning to use AM6442 in our custom board which has MAC to MAC RGMII interface.

So, could you please confirm which ethernet ports in AM6442 has MAC to MAC support(CPSW or PRU_ICSSG).

Warm Regards,

Hello Mythili,

Thanks for reaching out to the Sitara hardware applications team !

Please refer the below paragraph of this E2E FAQ - AM64x/AM243x Design Recommendations / Custom board hardware design - Queries related to RMII interface and RMII TI EPHY

From hardware perspective both PRU-ICSS and CPSW3g shall support direct MAC to MAC connection over RGMII hardware interface between two Ethernet ports:

This shall be supported in hardware for:

PRU-ICSSG0: PRG0_RGMII1, PRG0_RGMII2 hw interfaces

PRU-ICSSG1: PRG1_RGMII1, PRG1_RGMII2 hw interfaces.

CPSW3g: RGMII1 and RGMII2 hw interfaces

For confirmation on TI software support of such configurations, please provide the software related data:

Type ( Linux or MCU + SDK) and version of the SDK ?

Thanks

Best Regards
