Compiling Jetson TX2 source code L4T 32.3.1
Introduction
This wiki page contains instructions to download and build kernel source code for Jetson TX2, several parts of this wiki were based in the document: NVIDIA Tegra Linux Driver Package Development Guide 32.3.
L4T 32.3.1 is used by JetPack 4.3 (You can get more information from jetpack-archive).
Build kernel
1. Download and install the Toolchain
NVIDIA recommends using the Linaro 7.3.1 2018.05 toolchain for L4T 32.3 (toolchain)
Download the pre-built toolchain binaries from: http://releases.linaro.org/components/toolchain/binaries/7.3-2018.05/aarch64-linux-gnu/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu.tar.xz
2. Download the kernel sources for L4T 32.3.1
wget https://developer.download.nvidia.com/embedded/L4T/r32-3-1_Release_v1.0/Sources/T210/public_sources.tbz2
Execute the following commands to extract the kernel sources:
tar -xvf public_sources.tbz2 cd Linux_for_Tegra/source/public JETSON_TX2_SOURCES=$(pwd) tar -xf kernel_src.tbz2
3. Compile kernel and dtb
cd $JETSON_TX2_SOURCES/Linux_for_Tegra/source/public/
CROSS_COMPILE=${HOME}/toolchain_bin_${VERSION}/${TOOLCHAIN_DIR}/bin/$CC_PREFIX
KERNEL_OUT=$JETSON_TX2_SOURCES/Linux_for_Tegra/source/public/build
KERNEL_MODULES_OUT=$JETSON_TX2_SOURCES/Linux_for_Tegra/source/public/modules
cd $JETSON_TX2_SOURCES/Linux_for_Tegra/source/public/
make -C kernel/kernel-4.9/ ARCH=arm64 O=$KERNEL_OUT tegra_defconfig
make -C kernel/kernel-4.9/ ARCH=arm64 O=$KERNEL_OUT menuconfig
