Original question:

TDA4VM: [DRA821U] Main CPSW RGMII issue

DRA821U: Main CPSW RGMII not work issue

Part Number: DRA821U

Tool/software:

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

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

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?

    Hi, 

    Can you please provide the changes made? 

    If you need RGMII connection, you need to set the phy-mode as "rgmii" relevant as per delay requirements. 

    Best Regards, 

    Sudheer

    You need to configure the CPSW Ports in RGMII Mode.
    Also, need to enable Pins for RGMII functionality, refer to "mcu_cpsw_pins_default" from "k3-j7200-common-proc-board.dts" file where CPSW2G pins configured in RGMII Mode.

    Can you confirm, ETHFW is not loaded on MCU2_0 core? It can happen only when CPSW5G is controlled/configured by other core.

    Thanks for your mentions, I tried remove the default fw in "/lib/firmware/j8200-main-r5f0_0.fw" , then it work fine.

    But I still curious about what the use of ethfw, seems it's not necessary?

    Hi, 

    CPSW5G can be controlled by A72 With HLOS like Linux where only A72 can receive and send the data from /through cpsw. 

    We have another application named ETHFW server controlling CPSW5G and remote clients (Linux/RTOS/Autosar) can also receive and send the data from/to cpsw. 

    As per your use-case one will choose which application has to runn for CPSW5G. 

    Best Regards, 

    Sudheer

    I see, so if I don't need remote process, then I just need to remove all ETHFW files, am I right?

    Yes, If you don't want sharing CPSW with remote clients then you have to disable ETHFW application mapping to MCU2_0 core.
