基础镜像制作

• 安装编译依赖工具

sudo apt install build-essential bc
sudo apt-get install git bison flex libssl-dev zip libncurses-dev make git
sudo apt-get install build-essential bc

创建工具链放置目录

mkdir $HOME/l4t-gcc-toolchain
cd $HOME/l4t-gcc-toolchain

• 下载并解压交叉编译工具链

wget https://developer.nvidia.com/downloads/embedded/l4t/r36_release_v3.0/toolchain/aarch64--glibc--stable-2022.08-1.tar.bz2
tar xf aarch64--glibc--stable-2022.08-1.tar.bz2

• 进入到缓存好的刷机固件目录

cd $HOME/nvidia/nvidia_sdk/JetPack_6.2.1_Linux_JETSON_ORIN_NANO_TARGETS/Linux_for_Tegra/source  #根据实际目录进行修改
