# Inside the sources, directory, make an output directory for built kernel files using <code>mkdir kernel_out</code>.
# Build the modules using the command <code>./nvbuild.sh -o kernel_out</code>. This will compile the drivers and device trees for the new kernel.#Navigate out from the <code>sources</code> directory into the <code>Linux for Tegra</code>.# Use the <code>cp</code> to overwrite <code>./rootfs/usr/lib/modules/5.15.136-tegra/updates/nvgpu.ko</code> with <code>./source/kernel_out/nvgpu/drivers/gpu/nvgpu/nvgpu.ko</code>.# Repeat the previous step to replace <code>Linux_for_Tegra/kernel/dtb/</code> with# To specify the installation path for the compiled modules, use the command <code>export INSTALL_MOD_PATH=$HOME/nvidia/nvidia_sdk/JetPack_6.0_Linux_JETSON_AGX_ORIN_TARGETS/Linux_for_Tegra/rootfs/</code>. # Install modules using the command <code>./nvbuild -i</code>. == Flashing the Kernel ==# Ensure that
