*编译工具链
请参考[https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fxavier_toolchain.html%23wwpID0ESHA 这个链接]安装编译工具链。
*L4T源码和Rootfs
首先使用SDK Manager在HOST PC上面下载对应的Linux_for_Tegra开发包。
可以通过SDK Manager或者[https://developer.nvidia.com/embedded/downloads 直接下载]两种方式来获得源码。具体参考官方文档，此处不再赘述。
使用SDK Manager时同步代码采用如下指令：
''- 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>
*配置开发环境
以下步骤假设SDK安装目录为<TOPDIR>，源代码在$L4T_DIR/sources目录。
<code>export TOP_DIR=<absolute path to top dir accroding to your jetpack version and board name;for example /home/xumm/nvidia/nvidia_sdk/JetPack_4.5_Linux_JETSON_XAVIER_NX_DEVKIT/></code>
- 通用部分
<code>export L4T_DIR=$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>
<code>cd $L4T_DIR/sources/kernel/kernel-4.9/</code>
以下操作均为在HOST PC进行。
