I am trying to get the RGMII code from the r35.2.1/DeveloperGuide to work with my JP5.1.1. L35.3.1 dev env.
I successfully convert the tegra234-p3701-0000-p3737-0000.dtb file to a .dts and edit it but when I try to translate it back to a .dtb I get the following error:
der@der:~/Desktop/device_tree/Orin$ dtc -I dts -O dtb -o ./tegra234-p3701-0000-p3737-0000.dtb 360SA.dts Error: 360SA.dts:1704.47-48 syntax error FATAL ERROR: Unable to parse input tree der@der:~/Desktop/device_tree/Orin$
Other edits to the device tree worked to fix USB and disable the 10Gb Ethernet so I know the process is working. I suspect that the definitions for TEGRA234_MAIN_GPIO and tegra_main_gpio have been broken in JP5.1.1. L35.3.1 similarly to how the pinmux spreadsheet was broken.
The following lines give errors:
nvidia,phy-reset-gpio = <&tegra_main_gpio TEGRA234_MAIN_GPIO(G,5) 0>; Error: 360SA.dts:1704.47-48 syntax error interrupt-parent = <&tegra_main_gpio>; ERROR (phandle_references): /ethernet@2310000/mdio/phy@1: Reference to non-existent node or label "tegra_main_gpio" interrupts = <TEGRA234_MAIN_GPIO(G,4) IRQ_TYPE_LEVEL_LOW>; Error: 360SA.dts:1720.21-22 syntax error
Here are my files:
Some background: The 360SA custom carrier board works well with Xavier modules. The ORIN modules are working well with the exception of the Ethernet issues. Because the 1Gb Ethernet works with the Xavier SOMs we do not expect hardware issues with the Ethernet. I was able to get some activity by trying to hardcode the references but I don’t have the background to do that properly so I got the errors below:

Pin mux seems to be in place. Mem dump:

I hope that you may be able to help with this and get us going quickly.
Thank you for your time.
