源碼解壓，按照下面路徑配置
tar xvf public_sources.tbz2 -C ~/JetsonAGXKernel
tar xvf Tegra186_Linux_R32.5.0_aarch64.tbz2 ~/JetsonAGXKernel
tar xvf Tegra_Linux_Sample-Root-Filesystem_R32.5.0_aarch64.tbz -C ~/JetsonAGXKernel/Linux_for_Tegra/rootfs
cd ~/nvidia/Linux_for_Tegra/source/public
tar xvf kernel_src.tbz2 #這個(gè)是內(nèi)核源碼
配置交叉編譯環(huán)境
tar xvf gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu.tar.xz -C ~/L4t_arm_compiler#路徑自行決定
環(huán)境變量配置周崭，配置到bash里柳譬，后面不用再刪除
export TEGRA_AGX_KERNEL_OUT=/home/fuhua/JetsonAGXKernel/Linux_for_Tegra/source/public/kernel/output#路徑可以自己定義，記住這個(gè)后面有用
export LOCALVERSION=-tegra
CROSS_TOOL_PATH=/home/fuhua/L4t_arm_compiler/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-#上面解壓出來(lái)的交叉編譯環(huán)境路徑
export PATH=$PATH:$CROSS_TOOL_PATH
編譯
生成配置文件
make ARCH=arm64 CROSS_COMPILE=$CROSS_TOOL_PATH O=$TEGRA_AGX_KERNEL_OUT tegra_defconfig
按需調(diào)整配置文件续镇，不需要不管
make ARCH=arm64 CROSS_COMPILE=$CROSS_TOOL_PATH O=$TEGRA_AGX_KERNEL_OUT menuconfig
編譯
make ARCH=arm64 CROSS_COMPILE=$CROSS_TOOL_PATH O=$TEGRA_AGX_KERNEL_OUT -j8
組成文件系統(tǒng)美澳，從output，也就是編譯好的文件路徑里拷貝以下內(nèi)容到指定路徑
cd $TEGRA_AGX_KERNEL_OUT
cp arch/arm64/boot/Image /home/fuhua/JetsonAGXKernel/Linux_for_Tegra/kernel/Image
cp arch/arm64/boot/dts/* /home/fuhua/JetsonAGXKernel/Linux_for_Tegra/kernel/dtb/
在output路徑下執(zhí)行
sudo make ARCH=arm64 modules_install INSTALL_MOD_PATH=$TOP_PATH/rootfs/
燒錄
cd /home/fuhua/JetsonAGXKernel/Linux_for_Tegra
1 關(guān)閉agx 所有電源
2 接好3個(gè)按鍵旁邊的typeC口到PC
3 接上電源
4 按下中間的Recovery按鍵不放
5 按一下電源按鍵摸航，燈亮
6 等待5秒中制跟，放開(kāi)中間的Recovery按鍵
7 查看是否進(jìn)入強(qiáng)制恢復(fù)模式
lsusb
顯示為nvidia corp設(shè)備即可，顯示為L(zhǎng)4T是正常連接酱虎，沒(méi)有進(jìn)入恢復(fù)模式
8 在pc上執(zhí)行
sudo ./flash.sh jetson-agx-xavier-devkit mmcblk0p1
