=====烧写标准版本镜像=====

'''''注意：如您的Jetson板子已经正确烧写了标准版本的镜像，此步骤可以跳过。'''''

−

*编译工具链

+

可以使用SDK Manager直接烧写标准镜像，也可以按照如下步骤手动烧写。

−

~~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

−

~~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>~~

+

*配置环境变量

−

~~''- Jetpack4.3''~~

+

以下步骤假设SDK安装目录为<TOPDIR>。

−

~~<code>./source_sync.sh -t tegra-l4t-r32.3.1</code>~~

+

<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>

−

~~''- 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>~~

−

*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。~~

−

~~''- Nano@Jetpack4.2.2''~~
