目前是使用R35.1
Quick Guide

$ wget https://developer.nvidia.com/embedded/l4t/r35_release_v1.0/release/jetson_linux_r35.1.0_aarch64.tbz2
$ wget https://developer.nvidia.com/embedded/l4t/r35_release_v1.0/release/tegra_linux_sample-root-filesystem_r35.1.0_aarch64.tbz2
$ tar -xf jetson_linux_r35.1.0_aarch64.tbz2
$ cd Linux_for_Tegra/rootfs/
$ cp your_path/tegra_linux_sample-root-filesystem_r35.1.0_aarch64.tbz2 ./
$ sudo tar xpf tegra_linux_sample-root-filesystem_r35.1.0_aarch64.tbz2
( sudo must be used. Otherwise, get an error message from apply_binaries.sh)

cd ..
sudo ./apply_binaries.sh

Build Kernel:

• Download kernel source code from git:

  cd Linux_for_Tegra/
  ./source_sync.sh (此檔在r36.3的位置換了..., 在 source底下)
  When prompted enter a ‘tag’ name, as provided in the release notes.
  
  tag name:
  (Open another terminal after running source_sync.sh)
  $ cd Linux_for_Tegra/sources/kernel/kernel-4.9
  $ git tag -l tegra-l4t*
  
  jetson-r34.1_dp
  jetson_34.1.1
  jetson_35.1
  
  $ cd sources/
  

• Toolchain: Download as required

  list
  
  download, gcc 9.3.0
  

• drivers/video/Kconfig:27: can’t open file “drivers/video/tegra/Kconfig”

  modify source_sync.sh

  $ ./source_sync.sh
  $ cd Linux_for_Tegra/sources/kernel/nvidia
  $ cp -r drivers/video/tegra/  ../../kernel/kernel-5.10/drivers/video 
  
  

• Build the kernel image with the following build.sh:

    #!/bin/bash
  
    pwd=$(dirname $(readlink -f $0))
    TEGRA_KERNEL_OUT=out
    export CROSS_COMPILE=/opt/gcc/aarch64--glibc--9.3/bin/aarch64-linux-
    export LOCALVERSION=-tegra1
  
    if [ -z "$TEGRA_KERNEL_OUT" ]; then
        mkdir -p $TEGRA_KERNEL_OUT
        fi
  
    make ARCH=arm64 O=$TEGRA_KERNEL_OUT tegra_defconfig
  
    make ARCH=arm64 O=$TEGRA_KERNEL_OUT -j8
  
  

燒到板子...

$ cp out/arch/arm64/boot/Image Linux_for_Tegra/kernel/
$ sudo ./apply_binaries.sh
