DRA821U: Modifying MAC port mode in ethfw

Part Number: DRA821U
Other Parts Discussed in Thread: DRA829, DRA821

Hi,

For some reason, I need to use RGMII in ethfw in TI-RTOS, but the code provided as well as the official EVM board use QSGMII. What should I modify in ethfw to configure the MAC mode of the port?

If I want to put the port in MAC to MAC mode, what else do I need to modify?

    Hi,

    To enable RGMII for DRA821, you can look at the DRA829 implementation which uses RGMII for CPSW 9G by default. The two implementations are quite similar. In fact if you see the main_tirtos.c file in <ethfw\apps\app_remoteswitchcfg_server\mcu_2_0> you will see configuration for both QSGMII and RGMII.

    This FAQ provides details on what is required to setup a MAC 2 MAC connection on DRA821. The accompanying document also provides references.

    Regards
