ARM Cross Compiler: GCC
This is a pre-built (64bit) version of Linaro GCC that runs on generic linux, sorry (32bit) x86 users, it's time to upgrade...

Setup microSD card
For these instruction we are assuming, DISK=/dev/mmcblk0, lsblk is very useful for determining the device id.
export DISK=/dev/mmcblk0
Erase partition table/labels on microSD card:
sudo dd if=/dev/zero of=${DISK} bs=1M count=10
Install Bootloader:
sudo dd if=./u-boot/u-boot-dtb.imx of=${DISK} seek=2 bs=512
Create Partition Layout:
With util-linux v2.26, sfdisk was rewritten and is now based on libfdisk.
sudo sfdisk --version sfdisk from util-linux 2.27.1
sudo sfdisk ${DISK} <<-__EOF__ 1M,,L,* __EOF__
sudo sfdisk --unit M ${DISK} <<-__EOF__ 1,,L,* __EOF__
Format Partition:
for: DISK=/dev/mmcblk0 sudo mkfs.ext4 -L rootfs ${DISK}p1 for: DISK=/dev/sdX sudo mkfs.ext4 -L rootfs ${DISK}1
Mount Partition:
On most systems these partitions may will be auto-mounted...
sudo mkdir -p /media/rootfs/ for: DISK=/dev/mmcblk0 sudo mount ${DISK}p1 /media/rootfs/ for: DISK=/dev/sdX sudo mount ${DISK}1 /media/rootfs/
Install Kernel and Root File System
To help new users, since the kernel version can change on a daily basis. The kernel building scripts listed on this page will now give you a hint of what kernel version was built.
----------------------------- Script Complete eewiki.net: [user@localhost:~$ export kernel_version=4.X.Y-Z] -----------------------------
Copy and paste that "export kernel_version=4.X.Y-Z" exactly as shown in your own build/desktop environment and hit enter to create an environment variable to be used later.
export kernel_version=4.X.Y-Z
Copy Root File System
sudo tar xfvp ./*-*-*-armhf-*/armhf-rootfs-*.tar -C /media/rootfs/ sync sudo chown root:root /media/rootfs/ sudo chmod 755 /media/rootfs/
Set uname_r in /boot/uEnv.txt
sudo sh -c "echo 'uname_r=${kernel_version}' >> /media/rootfs/boot/uEnv.txt"
Copy Kernel Image
Kernel Image:
sudo cp -v ./armv7-multiplatform/deploy/${kernel_version}.zImage /media/rootfs/boot/vmlinuz-${kernel_version}
Copy Kernel Device Tree Binaries
sudo mkdir -p /media/rootfs/boot/dtbs/${kernel_version}/ sudo tar xfv ./armv7-multiplatform/deploy/${kernel_version}-dtbs.tar.gz -C /media/rootfs/boot/dtbs/${kernel_version}/
Copy Kernel Modules
sudo tar xfv ./armv7-multiplatform/deploy/${kernel_version}-modules.tar.gz -C /media/rootfs/
File Systems Table (/etc/fstab)
sudo sh -c "echo '/dev/mmcblk1p1 / auto errors=remount-ro 0 1' >> /media/rootfs/etc/fstab"
Remove microSD/SD card
sync sudo umount /media/rootfs
