DP83867 1G Phy is not working

1. Read your board config. If you don’t know what is “board config”, tell me how you flash your board…

2. Then please ask the vendor to provide PHY driver…

Hi Wayne,

I am flashing the board via USB 2.0 and by giving apply binary command after following kernel customization procedure. And then -
$ sudo ./flash.sh mmcblk0p1

Thanks

You just remove the board config by yourself…

$ sudo ./flash.sh mmcblk0p1

[sagar.kumar2]

$ sudo ./flash.sh Jetson-orin-dev-kit mmcblk0p1

The issue i am seeing since RGMII is not by default enable in the devkit so for that first we need to change the pinmux which we changed as per excel sheet. and then save those pin mux and gpio file here-

So just want to know it is right procedure way to enable RGMII sections . since we are seeing driver is not loading in kernel itself.

Thanks
Sagar

Jetson-orin-dev-kit

Then check Jetson-orin-dev-kit.conf in your Linux_for_Tegra directory and it will tell you which pinmux file you are using. Remember this because this happens to all Jetson platforms…

Right procedure are all listed here.

If driver is not loaded, then it could mean this driver is not present in our kernel. You need to check with the PHY vendor what driver is in use.
