I would suggest you try to with jetpack4 first if this is your first time doing bring up of sdmmc3. Also, get some basic knowledge of device tree and linux kernel. Share us the dmesg and your finalized dts file converted back from dtb… We don’t look into all dtsi files… ---

I guess your problem is not how to modify device tree… currently, your issue looks more like your device tree didn’t get updated on the device at all… ---

The whole dtb path which I put that should be Linux\_for\_Tegra/kernel/dtb/ And the dtb I built path that should be build/arch/arm64/boot/dts/\* I use the following command to update the device tree sudo ./flash.sh -r -k kernel-dtb jetson-xavier-nx-devkit-emmc mmcblk0p1 ---

Default dtb is read from rootfs in jp5. Which means what you just did won’t take effect… ---
