DRA821U: Main CPSW RGMII not work issue

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?

您好，

已经收到了您的案例，调查需要些时间，感谢您的耐

,

guangtao wu：

请问有什么排查方法吗，我尝试改了不同的phy-mode,也根据官方文档参考 RGMII 模式对应的 "k3-j721e-evm-gesi-exp-board.dtso" 文件适配了DRA821U , 也是一样的，都会报错 "PSI-L request err -22.".
