Hi @JerryChang , sure!
I’m on Ubuntu 20.04. I have downloaded the sources using sdkmanager (Jetpack 5.0.2) and get the kernel sources using source_sync.sh (this one: Jetpack5.0.2 kernel compile error - #12 by ShaneCCC) with branch jetson_35.1 when requested.
Once in kernel-5.10 folder I usually do:
sudo make clean
sudo make ARCH=arm64 LOCALVERSION=-tegra CROSS_COMPILE=${TOOLCHAIN_PREFIX} tegra_defconfig
sudo make ARCH=arm64 LOCALVERSION=-tegra CROSS_COMPILE=${TOOLCHAIN_PREFIX} -j16
sudo make ARCH=arm64 LOCALVERSION=-tegra CROSS_COMPILE=${TOOLCHAIN_PREFIX} modules_install INSTALL_MOD_PATH=…/…/…/rootfs/
cp arch/arm64/boot/Image …/…/…/kernel/Image
cp --verbose arch/arm64/boot/dts/nvidia/*.dtb …/…/…/kernel/dtb/
cd …/…/…/rootfs/
sudo tar --owner root --group root -cjf kernel_supplements.tbz2 lib/modules
cp kernel_supplements.tbz2 …/kernel/kernel_supplements.tbz2
cd …
sudo ./apply_binaries.sh
sudo ./flash.sh jetson-xavier-nx-devkit-emmc mmcblk0p1
I then do the Ubuntu initial setup and I try the command after rebooting.
