Jetson 把玩记三、自制最小文件系统镜像

目前JETPACK SDK镜像是4.5.1版

Jetson Nano 4G 内存版，下载链接：https://developer.nvidia.com/jetson-nano-sd-card-image

Jetson Nano 2G内存版，下载链接：https://developer.nvidia.com/jetson-nano-2gb-sd-card-image

系统镜像6G，默认安装ubuntu desktop等桌面软件，体积非常大，如果项目开发完成，想要将工程文件直接集成到镜像里，进行批量烧录，那么可以通过自制镜像的方式来实现。以下针对Nano版整理的制作方法。

一、下载BSP并解压

wget https://developer.nvidia.com/embedded/l4t/r32_release_v5.1/r32_release_v5.1/t210/jetson-210_linux_r32.5.1_aarch64.tbz2
tar xvf jetson-210_linux_r32.5.1_aarch64.tbz2
cd Linux_for_Tegra

wget https://developer.nvidia.com/embedded/l4t/r32_release_v5.1/r32_release_v5.1/t210/jetson-210_linux_r32.5.1_aarch64.tbz2

tar xvf jetson-210_linux_r32.5.1_aarch64.tbz2

cd Linux_for_Tegra

二、host安装依赖

apt-get update
apt-get install --no-install-recommends -y qemu-user-static debootstrap binfmt-support coreutils parted gdisk e2fsprogs

1 2	apt-get update apt-get install --no-install-recommends -y qemu-user-static debootstrap binfmt-support coreutils parted gdisk e2fsprogs

三、运行debootstrap创建基础rootfs

debootstrap --arch=arm64 --foreign --variant=minbase --include=python3,python3-apt bionic rootfs

tee rootfs/etc/apt/sources.list &lt;&lt;-'EOF'
deb http://ports.ubuntu.com/ubuntu-ports/ bionic main restricted universe multiverse
deb http://ports.ubuntu.com/ubuntu-ports/ bionic-security main restricted universe multiver
deb http://ports.ubuntu.com/ubuntu-ports/ bionic-updates main restricted universe multiverse
deb http://ports.ubuntu.com/ubuntu-ports/ bionic-backports main restricted universe multiverse
EOF

tee rootfs/etc/netplan/netcfg.yaml &lt;&lt;-'EOF'
network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
    dhcp4: true
EOF

cp /usr/bin/qemu-aarch64-static rootfs/usr/bin
chroot rootfs /bin/bash -c "/debootstrap/debootstrap --second-stage"

debootstrap --arch=arm64 --foreign --variant=minbase --include=python3,python3-apt bionic rootfs

tee rootfs/etc/apt/sources.list <<-'EOF'

deb http://ports.ubuntu.com/ubuntu-ports/ bionic main restricted universe multiverse

deb http://ports.ubuntu.com/ubuntu-ports/ bionic-security main restricted universe multiver

deb http://ports.ubuntu.com/ubuntu-ports/ bionic-updates main restricted universe multiverse

deb http://ports.ubuntu.com/ubuntu-ports/ bionic-backports main restricted universe multiverse

EOF

tee rootfs/etc/netplan/netcfg.yaml <<-'EOF'

network:

version: 2

renderer: networkd

ethernets:

eth0:

dhcp4: true

EOF

cp /usr/bin/qemu-aarch64-static rootfs/usr/bin

chroot rootfs /bin/bash -c "/debootstrap/debootstrap --second-stage"

四、target安装依赖

此时需要chroot到rootfs内

chroot rootfs /bin/bash

apt update

apt install -y libx11-dev libgles2 libpangoft2-1.0-0 libharfbuzz0b libgles2 libdatrie1 libxkbcommon0 libwayland-egl1 libwayland-cursor0 libunwind8 libpng16-16 libpixman-1-0 libjpeg-turbo8 libinput10 libgles2 libevdev2 libcairo2 device-tree-compiler iso-codes libffi6 libncursesw5 libpython3-stdlib libpython3.8-minimal libpython3.8-stdlib libreadline7 libtinfo5 python3-minimal python3.8 libglvnd0 libdrm-common libdrm2 libegl-mesa0 libegl1 libegl1-mesa libgtk-3-0 libgbm1 libglapi-mesa libwayland-server0 libx11-xcb1 libxcb-dri3-0 libxcb-present0 libxcb-sync1 libxcb-xfixes0 libxshmfence1 libgstreamer1.0-0 libgstreamer-plugins-bad1.0-0 libpangocairo-1.0-0 libasound2 libasound2-data libpython-stdlib libpython2.7-minimal libpython2.7-stdlib python python-minimal python2.7 python2.7-minimal

apt install -y bash-completion build-essential btrfs-progs cmake curl dnsutils htop iotop isc-dhcp-client iputils-ping kmod linux-firmware locales net-tools netplan.io pciutils python3-dev ssh systemd udev unzip usbutils wpasupplicant vim

locale-gen&nbsp; en_US.UTF-8

rm /dev/random
rm /dev/urandom

exit

./apply_binaries.sh&nbsp;

chroot rootfs /bin/bash

apt update

apt install -y libx11-dev libgles2 libpangoft2-1.0-0 libharfbuzz0b libgles2 libdatrie1 libxkbcommon0 libwayland-egl1 libwayland-cursor0 libunwind8 libpng16-16 libpixman-1-0 libjpeg-turbo8 libinput10 libgles2 libevdev2 libcairo2 device-tree-compiler iso-codes libffi6 libncursesw5 libpython3-stdlib libpython3.8-minimal libpython3.8-stdlib libreadline7 libtinfo5 python3-minimal python3.8 libglvnd0 libdrm-common libdrm2 libegl-mesa0 libegl1 libegl1-mesa libgtk-3-0 libgbm1 libglapi-mesa libwayland-server0 libx11-xcb1 libxcb-dri3-0 libxcb-present0 libxcb-sync1 libxcb-xfixes0 libxshmfence1 libgstreamer1.0-0 libgstreamer-plugins-bad1.0-0 libpangocairo-1.0-0 libasound2 libasound2-data libpython-stdlib libpython2.7-minimal libpython2.7-stdlib python python-minimal python2.7 python2.7-minimal

apt install -y bash-completion build-essential btrfs-progs cmake curl dnsutils htop iotop isc-dhcp-client iputils-ping kmod linux-firmware locales net-tools netplan.io pciutils python3-dev ssh systemd udev unzip usbutils wpasupplicant vim

locale-gen  en_US.UTF-8

rm /dev/random

rm /dev/urandom

exit

./apply_binaries.sh 

五、编译镜像

cd tools

4G版：

./jetson-disk-image-creator.sh -o jetson_4G.img -b jetson-nano -r 300

*(100/200/300 for A01/A02/B00)

2G版：

./jetson-disk-image-creator.sh -o jetson_2G.img -b jetson-nano-2gb-devkit

-rw-r–r– 1 root root 1.8G Jul 11 15:57 jetson.img

基础版镜像只有1.8G，需要什么加什么。

六、烧录镜像

dd if=jetson_4G.img of=/dev/sdb bs=4M conv=fsync status=progress

根据读卡器识别不同，有些是sd设备，有些是mmc设备，根据情况来。

七、调整分区

比较复杂，参考脚本：https://raw.githubusercontent.com/pythops/jetson-nano-image/master/flash-image.sh

八、插电开机、成功启动
