−Please refer to：[[VEYE CS Camera for Jetson TX2#Setting Up the Host PC Environment|3.6.1 Setting Up the Host PC Environment]].
+The following operations are done in HOST PC.
+*Cross-compiling Toolchain
+Please refer to this [https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fxavier_toolchain.html%23wwpID0ESHA link] to install toolchain on your Host PC.
+*L4T source code and Rootfs
+Please download the Linux_for_Tegra SDK via SDK Manager first.
+You could use SDK Manager or [https://developer.nvidia.com/embedded/downloads directly download] to get source code.
−Sync code as this if you use SDK Manager:
+''- Jetpack4.2.2''
+<code>./source_sync.sh -t tegra-l4t-r32.2.1</code>
+''- Jetpack4.3''
+<code>./source_sync.sh -t tegra-l4t-r32.3.1</code>
+''- Jetpack4.4''
+<code>./source_sync.sh -t tegra-l4t-r32.4.3</code>
+''- Jetpack4.4.1''
+<code>./source_sync.sh -t tegra-l4t-r32.4.4</code>
+''- Jetpack4.5''
+<code>./source_sync.sh -t tegra-l4t-r32.5</code>
+''- Jetpack4.5.1''
+<code>./source_sync.sh -t tegra-l4t-r32.5.1</code>
+''- Jetpack4.5.1''
+<code>./source_sync.sh -t tegra-l4t-r32.5.1</code>
+*Setting Up the Environment
+Assume SDK install directory is <TOPDIR>，source code is in $L4T_DIR/sources directory.
+<code>export TOP_DIR=<absolute path to top dir accroding to your jetpack version and board name;for example /home/xumm/nvidia/nvidia_sdk/JetPack_4.5_Linux_JETSON_XAVIER_NX_DEVKIT/></code>
+<code>export L4T_DIR=$TOP_DIR/Linux_for_Tegra</code>
+<code>export LOCALVERSION=-tegra</code>
+<code>export LDK_ROOTFS_DIR=$TOP_DIR/Linux_for_Tegra/rootfs</code>
+<code>export ARCH=arm64</code>
+<code>export CROSS_COMPILE=aarch64-linux-gnu-</code>
+<code>export CROSS32CC=arm-linux-gnueabihf-gcc</code>
+<code>export TEGRA_KERNEL_OUT=$L4T_DIR/sources/kernel/out_kernel</code>
+<code>export KERNEL_PATH=$L4T_DIR/sources/kernel/out_kernel</code>
+<code>export NVIDIA_PATH=$L4T_DIR/sources/kernel/nvidia</code>
+<code>export NANO_DTS_PATH=$L4T_DIR/sources/hardware/nvidia/platform/t210/</code>
+<code>export TX2_DTS_PATH=$L4T_DIR/sources/hardware/nvidia/platform/t18x</code>
+<code>export XAVIER_DTS_PATH=$L4T_DIR/sources/hardware/nvidia/platform/t19x</code>
