Customising xavier nx boot order

[DavidJRobertson]

How do I change the cboot boot order on the Xavier NX?

On the AGX Xavier (not using OE4T) I used a script like below to do it. I assume that means I need to do something similar with creating a cbo.dtb but I am not really sure where to put my cbo.dts to have it built and included in the tegraflash image.

dtc -I dts -O dtb -o cbo.dtb << EOF
	/dts-v1/;
	/ {
		compatible = "nvidia,cboot-options-v1";
		boot-configuration {
			boot-order = "sd", "emmc", "nvme", "usb";
		};
	};
EOF

dd if=cbo.dtb of=/dev/disk/by-partlabel/CPUBL-CFG

It's a two-step process. The first step is to add a recipe with your cbo.dts file. Next is to add a bbappend
for the tegra-bootfiles recipe to have it depend on your new recipe and set CBOOTOPTION_FILE to point
to the file. I have an example in my test distro repo: recipe to install the file, bbappend for tegra-bootfiles

Thanks, didn't see that. Got it working now.
