Part Number: TDA4VH-Q1
Hello
SDK:9.2
I am using the Linux device tree overlay k3-j784s4-evm-quad-port-eth-exp1.dtbo, with the following configuration:
- 2 × SGMII connected to 1Gbps PHYs
- 2 × SGMII connected to a 2.5Gbps switch.
Why am I getting the following error?

Is there any problem with this device tree?
On Linux, how can I use multiple lanes from the same SerDes, where one lane runs SGMII at 1Gbps and another lane runs SGMII at 2.5Gbps?
Best Regards,
