Failure to boot with stock kernel when build from source

I am having trouble with our Jetson Orin NX 16GB booting after installing the kernel when built from source.

Here are the steps I am taking to build and install the kernel and flash the board:

Steps to build kernel and flash Jetson Orin NX 16GB

#Setup L4T Folder and exports
cd /home/${USER}/JetsonFlashing
sudo tar --same-owner -xvf Jetson_Linux_R36.2.0_aarch64.tbz2
sudo tar --same-owner -xvf Tegra_Linux_Sample-Root-Filesystem_R36.2.0_aarch64.tbz2 --directory Linux_for_Tegra/rootfs/
export TOOLCHAIN_PATH=/home/${USER}/Documents/JetsonFlashing/aarch64--glibc--stable-2022.08-1
export L4T_DIR=/home/${USER}/JetsonFlashing/Linux_for_Tegra

sudo ./apply_binaries.sh

cd ${L4T_DIR}/source




#Without this block in the middle, the board will flash and boot fine (after patching usb-gadget driver on r36.2 release)

I have attached the boot log from serial console as well as the flash log.

I’m not sure what we’re doing wrong. Our intent is to build the RT kernel, however, it fails to boot with or without patching RT

This line is a typo:

sudo ./l4t_generate_soc_bup.sh -b p3768-0000-p3767-0000-a0 t23x

It is supposed to read:

sudo ./l4t_generate_soc_bup.sh -b jetson-orin-nano-devkit t23x
