Linux/AM3352: Ethernet interface not up

newuser
Intellectual 630 points
Part Number: AM3352

Tool/software: Linux

Hello,

I have custom board based AM3352, and on my board I have two PHY of TI-DP83867 at address 0x0 and 0xF.

Ethernet is working at u-boot level, I can transfer files using tftp, hardware looks OK.

When I start linux, it boots-up successfully, but network interface is not up.

Please let me know what area I should look for so ethernet/phy comes up and networking works. I would like to get eth0, and eth1 both comes  up with DHCP mode.

I am using TI-SDK 4.03.00.05

 

I am using am335x-evm.dtb file and i haven't made any changes in corresponding .dts file. It looks like I have to make some changes based on my hardware. unfortunately I am not much familiar with .dts file if someone can explain me what kind of changes are required, I really appreciate.

Thanks,
NU.

    Hi newuser,

    Yes, you need to update your am335x-evm.dts linux file to match your custom board ethernet PHYs. Check below things:

    - pinmux, check if MDIO and CPSW pinmux is correct for your board and change if necessary
    - phy_id and phy-mode

    These changes should be same as for u-boot am335x-evm.dts file. As you state that u-boot is working fine, is this with default am335x-evm.dts file? If not, aligned your linux am335x-evm.dts file with you u-boot am335x-evm.dts file.

    u-boot/arch/arm/dts/am335x-evm.dts
    linux-kernel/arch/arm/boot/dts/am335x-evm.dts

    Refer also to the below files regarding DTS settings:

    linux-kernel/Documentation/devicetree/bindings/net/cpsw.txt
    linux-kernel/Documentation/devicetree/bindings/net/ethernet.txt

    Note also that TI DRA72XEVM is coming with dp83867 PHY, you can take its DTS file for reference:

    linux-kernel/arch/arm/boot/dts/dra72-evm-revc.dts
    linux-kernel/Documentation/devicetree/bindings/net/ti,dp83867.txt

    Hello Pavel,

    Thx for your reply. on my board i have two TI PHY - DP83867 operating in rgmii2 mode, connected at address 0x0 and 0xF.

    eth_0, at address 0x0 is working at U-boot level, i can xfer file and no issue for that one.

    for U-Boot I am not using .dts file, all setting are done in code using mux.c in u-boot.

     

    Now I have started working on linux for AM3352 and i want my both eth0 and eht1 i am having for trouble to make both interface up.

    I have attached my logs, as well as modified .dts file. 

    do i have to make any change in PHY driver code? i see in driver code dp83867.c PHY device address is hard coded to 0x1F, so how it is going to work for two phys? can you explain me.

    Also on my board i have only one UART - UART_0, and no USB. so I made some changes in .dts file but now I see more warning/error and not sure how to fix that one?

    At this stage, I can see for eth0  - LINK and activity LED active.

    But as soon as I set some static ip address for eth0, both LED get turn OFF.

    Do I need to load any other modules? do you think something might be wrong with my start-up script?

    Thx for your reply. on my board i have two TI PHY - DP83867 operating in rgmii2 mode, connected at address 0x0 and 0xF.

    We do not have RGMII2 mode available. Do you mean RGMII mode?

    newuser said:
    Now I have started working on linux for AM3352 and i want my both eth0 and eht1 i am having for trouble to make both interface up.

    newuser said:
    I have attached my logs, as well as modified .dts file. 

    You should also add "dual_emac" property in your DTS. Note that Am335x TI EVM is coming with single ethernet PHY, that is way "dual_emac" is missing from EVM DTS file. AM335x SK comes with the ethernet PHYs, and "dual_emac" is used in am335x-evmsk.dts file, please use as a reference.

    newuser said:
    do i have to make any change in PHY driver code? i see in driver code dp83867.c PHY device address is hard coded to 0x1F, so how it is going to work for two phys? can you explain me.

    This is Sitara forum and I can help you with Sitara AM335x device. regarding questions specific for DP83867 PHY and its driver, you should ask/post in ethernet phy forum:

    newuser said:
    Also on my board i have only one UART - UART_0, and no USB. so I made some changes in .dts file but now I see more warning/error and not sure how to fix that one?

    This is not related to ethernet PHY integration, so I would suggest you to open new e2e thread in Sitara forum regarding UART/USB related issues.

    In your previous post you stated that you are using PSDK v4.03. have you made a switch to latest PSDK v5.00? If yes, not that PSDK v5.00 is using newer linaro GCC version of 7.2.1

    Hello Pavel,

    Thanks for your reply. After adding "dual_emac" now i can see both eth0 and eth1. and both gets link-up. I can see activity and link LED is blinking/steady.

    At present I am using my own rootfs - and it looks like something is not setup correctly for networking to work either for static as well as for dhcp. I tried both mode.

    Do you have any pointer ,OR  can you guide me what minimum scripts / software are required in my file system so static as well as DHCP mode can work.

    Thanks,

    NU.

    Hello Pavel,

    To simplify, now I am focusing only one ethernet eth0 - with DP83867 with PHY address 0x0. I have attached my log.

    Still I am not able to make out why ethernet is not working? I can see link and activity LED is blinking, but static as well as dynamic IP address mode for ethernet is not working.

    Any clue? Do I have to do anything with PHY interrupt? at present it is connected to GPIO_3_0. does driver is using PHY interrupt?

    Do I have to modify .dts / .dtsi file this PHY interrupt which is connected to GPIO_3_0?

    Hello Pavel,

    Issue was with my DTS file, now it is fixed. I have attached my DTS file - may be useful to someone.

    Now i have two more issue left related to networking, I was thinking of opening a separate ticket, but if you can answer in this thread that will be great.

    On my customer board I have two wired ethernet ETH_0 and ETH_1, with TI-PHY.

    Issue # 1: ETH_0 is working in static mode, but dhcp - I have to do manually issue command ifup/ifdown couple of time, and ifconfig eth0 dynamic. I have default script for dhcpc, but it doesn't get executed automatically. I have created my on rootfs - so it looks like I am missing something. If you can help me on this that will be great.

    Issue #2: My second ethernet ET_1 is not up, I can see activity and link LED is blinking.

                      I have two use case

                     a) ETH_0 and ETH_1 both are on same subnet. is it same as switch ?

                     b) ETH_0 and ETH_1 are on different subnet. / each port connected to two different router.

                           e.g. eth0 192.168.0.1, 255.255.255.0 gw-192.168.0.100

                                    eth1 10.20.30.1,  255.255.255.0 gw-10.20.30.100.

    Is it possible to get both use case?

    Thanks,

    NU.
