Original question:

TDA4VM: How do I make sure we have correct RGMII pinmux setting for CPSW9G?

TDA4VM: RGMII interface internal rx delay configuration

Part Number: TDA4VM

Hello, We are CPSW0/9G from A72 core using linux drivers. We have connected SJA1105TEL switch to CPSW9G but we are facing internal delay(propagation delay) and our switch don't have internal delay adjustment feature. Could you please confirm how the RX delay can be configured in the CPSW9G?

Thanks,

Prashant K

    CPSW doesn't have control of Rx delay as it is the responsibility of PHY (Which generates RXC). It has configuration support for Tx Delay alone as TXC is generated by MAC.

    If PHY is not supported, it has to be controlled from PCB Board Design.
