Setup microSD/SD card
For these instruction, we are assuming: DISK=/dev/mmcblk0, "lsblk" is very useful for determining the device id.
$ export DISK=/dev/mmcblk0 (我的电脑为$ export DISK=/dev/sdb)
Erase microSD/SD card:
$ sudo dd if=/dev/zero of=${DISK} bs=1M count=10
Install Bootloader:
~/
$ sudo dd if=./u-boot/u-boot.imx of=${DISK} bs=512 seek=2
Create Partition Layout:
$ sudo sfdisk --in-order --Linux --unit M ${DISK} <<-__EOF__
$ 1,,0x83,-
$ __EOF__

Checking that no-one is using this disk right now ...
BLKRRPART: 设备或资源忙


This disk is currently in use - repartitioning is probably a bad idea.
Umount all file systems, and swapoff all swap partitions on this disk.
Use the --no-reread flag to suppress this check.
Use the --force flag to overrule all checks.
【解决】
[root@fish lwg]# cat /etc/mtab //查看
$ umount /dev/sdb1


Format Partitions:
for: DISK=/dev/mmcblk0
sudo mkfs.ext4 ${DISK}p1 -L rootfs
 
for: DISK=/dev/sdX
$ sudo mkfs.ext4 ${DISK}1 -L rootfs


Mount Partitions:
On some systems, these partitions may 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=3.X.Y-Z]
-----------------------------
Copy and paste that "export kernel_version=3.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=3.X.Y-Z (我的电脑为$ export kernel_version=3.17.1-armv7-x3)


Copy Root File System
~/
$ sudo tar xfvp ./*-*-*-armhf-*/armhf-rootfs-*.tar -C /media/rootfs/
Create /boot/uEnv.txt

$ sudo mkdir -p /media/rootfs/boot/
$ sudo sh -c "echo 'uname_r=${kernel_version}' > /media/rootfs/boot/uEnv.txt"
Debian /boot/uEnv.txt (enable systemd)
~/
$ sudo sh -c "echo 'cmdline=quiet init=/lib/systemd/systemd' >> /media/rootfs/boot/uEnv.txt"
Copy Kernel Files

 Remove microSD/SD card:
sync
sudo umount /media/rootfs
