TE820 +TE0706 carrier Ethernet in u-boot

[pema]

Hi there,
I would like to enable ethernet in u-boot for the TE0820 (connected to gem3).
I added to the .../project-spec/meta-user/recipes-bsp/device-tree/files/system-user.dtsi

Code Select Expand


/*------------------ ETH PHY --------------------*/
&gem3 {
    /delete-property/ local-mac-address;
    phy-handle = <&phy0>;
    nvmem-cells = <&eth0_addr>;
    nvmem-cell-names = "mac-address";
    phy0: phy0@1 {
        device_type = "ethernet-phy";
        reg = <1>;
    };
};


Also tried :

Code Select Expand


&gem3 {
    /delete-property/ local-mac-address;
    phy-handle = <&phy0>;
    nvmem-cells = <&eth0_addr>;
    nvmem-cell-names = "mac-address"
    phy0: phy0@1 {
        device_type = "ethernet-phy";
        reg = <1>;
    };
};


As provided in the BSP for the TE0820. But this gives me an error during compilation.
is there any thing else that needs to be added to the kernel config or u-boot config?

The error output are little enigmatic for me:

any help would be appreciated. Kinda stuck and I just need this to speed up my development tryouts.
Many Thanks

So I made a dumb mistake with an inline comment in the device tree .
I can compile the device tree but I still get no ethernet detected in ubuntu

I got it now working. Needed to enable:
CONFIG_ZYNQ_GEM=y
CONFIG_DM_ETH=y
CONFIG_NET_RANDOM_ETHADDR=y
