Build the Real-Time Kernel

[wai.kwok.law]

Please let me know the following steps are the ones I have to go through in order to build and install Jetson Linux 35.1 real time kernel

1. Download Jetson Linux 35.1 BSP and sample root file system,
   • https://developer.nvidia.com/embedded/l4t/r35_release_v1.0/release/jetson_linux_r35.1.0_aarch64.tbz2
   • https://developer.nvidia.com/embedded/l4t/r35_release_v1.0/release/tegra_linux_sample-root-filesystem_r35.1.0_aarch64.tbz2
2. Perform the steps you suggest below to extract BSP and sample root file system assuming Linux_for_Tegra is the build directory

sudo tar xpf JAX-TX2-Jetson_Linux_R32.1.0_aarch64.tbz2
cd Linux_for_Tegra/rootfs/
sudo tar xpf ../../JAX-TX2-Tegra_Linux_Sample-Root-Filesystem_R32.1.0_aarch64.tbz2
cd ..
sudo ./apply_binaries.sh
sudo ./flash.sh --no-flash jetson-xxxx mmcblk0p1

3. Manually Downloading and Expanding Kernel Sources as described in the To Manually Download and Expand the Kernel Sources section of Kernel Customization — Jetson Linux<br/>Developer Guide 34.1 documentation
4. Apply RT patch and build the real-time kernel as described in the Building the Kernel section of Kernel Customization — Jetson Linux<br/>Developer Guide 34.1 documentation
5. Follow the instructions in the Preparing to Build External Kernel Modules section of Kernel Customization — Jetson Linux<br/>Developer Guide 34.1 documentation
6. Follow the instructions in the To Build External Kernel Modules section of Kernel Customization — Jetson Linux<br/>Developer Guide 34.1 documentation
7. Modify the /boot/extlinux/extlinux.conf to apply the real time kernel. How to use /boot/extlinux/extlinux.conf after jetpack 5.0 - #6 by linuxdev
