Unable to boot up Jetson Orin NX

[NavSriv]

I am using Diamond Systems Jetson Orin NX 16GB board for development. It has 128GB SSD on it. I am building image through
poky -> nanbield
meta-qt6 -> 6.6.1
meta-openembedded -> nanbield
meta-tegra -> nanbield

I have cross checked compatibility of all layers.

I have following change in my local.conf (file is attached for reference) local.txt

MACHINE ??= "p3768-0000-p3767-0000"

I had changed the jumpers to put it in recovery mode, extracted tegraflash file and executed following commands -

sudo ./initrd-flash and sudo ./doflash.sh

They both failed and threw below error -

I am not sure which direction to look into to diagnose the issue. My intention is only to change rootfile system for now.
Thank you and appreciate your help.

You need to install the dtc binary from your package repository. If you are on ubuntu you should run apt install device-tree-compiler also as a way to speed up the subsequent write speed also install bmap-tools.

Thanks this helped.. I am able to flash the drive successfully, though it killed the board with my image :)
