AM625SIP: Swapped RMII TXD0/TXD1 signals

Part Number: AM625SIP

Tool/software:

Hi,

We’re working with a custom PCB design based on the AM625SIP. The second Ethernet port is connected to a switch port (MAC-to-MAC) over RMII. Unfortunately, the TXD0 and TXD1 signals were swapped in the layout.

Is there any possibility of implementing a workaround for this in the Linux driver (ti,am654-cpsw-nuss)?

Regards,

Marcin

    Hello Marcin, 

    I need to consult the CPSW software developer on this. Currently I don't see a way even with any modification on device tree pinmux configuration to workaround this. We will need some time to look into the CPSW driver for this.

    Please kindly ping this thread by next Thursday if you don't hear a response by then.
