We are trying to be enable RGMII on AGX Orin.
I found the device-tree code as below:
Could I input this code to “tegra234-ethernet-3737-0000.dtsi”?
And case of AGX Xavier, It has device tree code for “ethernet@2490000” in “tegra194-power-tree-p2888-0001-p2822-1000.dtsi”
Does same thing need to AGX Orin?
Do I need to put the code to “tegra234-power-tree-p3701-0000-p3737-0000.dtsi” if does it need?
You only need to configure the things mentioned in the developer guide document.
I tried to be enable RGMII as follow:
I refer the dts file from above and modify dtsi file as below:
I can see the messages in related to RGMII address, but it’s all.
There is nothing more than it as I known.

There is no eth0 port on ifconfig list after boot.
So, I tried to be up the eth0, It doesn’t work.
And I have one more question about pinmux.
I used pinmux spreadsheet as below:
I can’t find any different on the dmesg before and after about pinmux changes for eqos.
Your pinmux totally not matches the result on document.
Sorry, I didn’t catch what you mean “the result on document”.
Open the L4T developer guide document. Search “RGMII” in the document and it will lead you to the guide.
If interrupt does not go up, please check the register as this post said.
Your pinmux may still have problem.
Thank you for the reply
There is no list about eth0 on interrupts.
And “ifconfig eth0 up” doesn’t work as below
Could you let me know what information does not updated to my device tree??
pinmux cfg file?? ethernet dtsi file? or both?
I’d be appreciate, if you point it out.
It means pinmux is still wrong. Check the register as above post said.
Not only GPIO. Every pin there should have correct state.
Previous pinmux file has the missed point what I didn’t changed.
It has fixed now.
I checked out several times the pinmux and l4t guide.
And I can’t find anymore different,
tegra234-mb1-bct-pinmux-p3701-0000-a04.dtsi (62.5 KB)
But the result are same.
