TDA4VH-Q1: Configure CPSW2G RGMII Rx/Tx skew delay in TDA4VH

Part Number: TDA4VH-Q1
Other Parts Discussed in Thread: TDA4VH

Tool/software:

Hi TI Experts,

We use the CPSW2G RGMII interface to connect another Soc, using the Mac-to-Mac connection mode.

Another Soc requires the TDA4 end to configure RGMII Rx delay as 2.

But we haven't found out how to configure Rx delay on the TDA4VH CPSW2G.

Could TI experts help provide information on how to configure the RGMII Rx delay of CPSW2G?

Hardware: TDA4VH

OS: TI SDK 11.00: Linux + RTOS

    Only RGMII Tx delay supported by MAC. Rx delay has to be controlled by PHY or peer side MAC via MAC Tx delay.

    If peer side MAC doesn't support delay, then it has to be enabled via Schematic traces.
