是否有适合在 ARM 处理器上运行的 8gb Cubox-i4 的 Ubuntu 映像？

Question

运行以下命令：

cd
mkdir rootfs 
debootstrap --foreign --include=vim,dialog,apt --variant=minbase --arch=armhf xenial rootfs http://ports.ubuntu.com

运行之后：

mount -o bind /dev rootfs/dev
mount -o bind /dev/pts rootfs/dev/pts
mount -t sysfs /sys rootfs/sys
mount -t proc /proc rootfs/proc
cp /proc/mounts rootfs/etc/mtab
chroot rootfs

现在在中chroot运行：

/debootstrap/debootstrap --second-stage
localedef -i en_XX -c -f UTF-8 en_XX.UTF-8 #replace XX with your country code
dpkg-reconfigure locales
dpkg-reconfigure tzdata
echo utilite > /etc/hostname

rm /sbin/initctl
dpkg-divert --local --rename --remove /sbin/initctl
exit

现在回到正常环境，运行：

cd
sudo apt-get install software-properties-common python-software-properties
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.9
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.8
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 40 --slave /usr/bin/g++ g++ /usr/bin/g++-4.9
sudo update-alternatives --config gcc
git clone -b boundary-imx_4.1.15_1.0.0_ga git://github.com/boundarydevices/linux-imx6.git
cd boundary-imx_4.1.15_1.0.0_ga
export PATH=/opt/freescale/usr/local/gcc-4.6.2-glibc-2.1
export ARCH=arm
export CROSS_COMPILE=arm-none-linux-gnueabi-
git checkout origin/boundary-imx_4.1.15_1.0.0_ga -b boundary-imx_4.1.15_1.0.0_ga
make nitrogen6x_defconfig
make uImage modules

INSTALL_MOD_PATH=~/rootfs make firmware_install
INSTALL_MOD_PATH=~/rootfs make headers_install

mkimage -A arm -O linux -T kernel -C none -a 0x10008000 -e 0x10008000 -n 3.10.17-cm-fx6-1-beta4-aufs -d /tmp/zImage-cm-fx6 /boot/uImage-cm-fx6
rm -f /tmp/zImage-cm-fx6

终于！我们快完成了。

将 Cubox 的前端口连接到计算机。现在运行：

sudo mount /dev/ttymxc3 /mnt
cd ~/rootfs
tar --numeric-owner –cpjf ~/xenial.tar.bz2 *

上述命令将需要很长时间。

旧版本的 U-Boot 固件需要一个vfat分区来加载内核映像。因此，您倾向于使用一个较小的vfat分区来保存内核映像，并使用一个较大的ext4分区来保存其余部分。在 ARM 平台上，第一个分区通常从扇区 2048 开始，如果您希望随后将 U-Boot 固件放在 uSD 上，则需要保留足够的空间。在 PC 平台上，您可以在创建分区方案时检查这一点：

echo -e "n\np\n1\n\n+100M\na\n1\nt\nc\nn\np\n2\n\n\nw\neof\n" | fdisk /dev/ttymxc

如果您已经更新了 U-Boot 固件和环境，则不再需要两个单独的分区。只需创建一个大ext4分区即可。

以 root 身份运行：mkfs.vfat -n boot /dev/ttymxc1 # 如果您需要 fat 分区 mkfs.ext4 -O ^has_journal -E stride=2,stripe-width=1024 -b 4096 -L rootfs /dev/ttymxc2 # 如果您不需要 fat 分区，请将最后 2 改为 1

mount /dev/ttymxc2 /mnt # change the last 2 to 1 if you didn't need a fat partition
mkdir /mnt/boot 
mount /dev/ttymxc1 /mnt/boot # exclude this if you didn't need a fat partition
tar --numeric-owner –xpjf ~/trusty.tar.bz2 –C /mnt
sync
cp ~/boundary-imx_4.1.15_1.0.0_ga/arch/arm/boot/uImage /mnt/boot/uImage-cm-fx6_3.0.35-6.1
sync
umount /mnt
umount /mnt/boot

终于。我们完成了！

我花了很长时间才找到正确的答案，如果我错了，请编辑它来修复它。
