Dear TI,
We made a new board with J7200(DRA821U), and use sdk "ti-processor-sdk-linux-j7200-evm-09_02_00_05".
The board have three ethernet ports, one mcu_cpsw, and two ports on Main CPSW.
For now, mcu_cpsw already work normal, but main cpsw ports not work, we used mofiled the dtso file "k3-j7200-evm-quad-port-eth-exp.dtso" as below, which already disabled unused port3 and port4
/dts-v1/;
/plugin/;

and we can see the eth0(mcu_cpsw) and eth1, eth2 on main cpsw by ifconfig command.

however, after set ip for eth1 or eth2, it ping failed, and print lots of logs as below.

I have tried to change "phy-mode" to "rgmii", "rgmii-rxid", "rgmii-id", but not work.
attach the dmesg log on boot as below.

we can see the error message "[ 4.680095] am65-cpsw-nuss c000000.ethernet: PSI-L request err -22" , but don't know why.
For this issue, how can I check next?
