h1. Setup microSD card
*For these instruction we are assuming, DISK=/dev/mmcblk0, lsblk is very useful for determining the device id.*
{code}
export DISK=/dev/mmcblk0
{code}
Erase partition table/labels on microSD card:
{code}
sudo dd if=/dev/zero of=${DISK} bs=1M count=10
{code}
Install Bootloader:
{code:title=~/}
sudo dd if=./u-boot/MLO of=${DISK} count=1 seek=1 bs=128k
sudo dd if=./u-boot/u-boot.img of=${DISK} count=2 seek=1 bs=384k
{code}
Create Partition Layout:
*With util-linux v2.26, sfdisk was rewritten and is now based on libfdisk.*
{code:title=sfdisk}
sudo sfdisk --version
sfdisk from util-linux 2.27.1
{code}
{code:title=sfdisk >= 2.26.x}
sudo sfdisk ${DISK} <<-__EOF__
4M,,L,*
__EOF__
{code}
{code:title=sfdisk <= 2.25.x}
sudo sfdisk --unit M ${DISK} <<-__EOF__
4,,L,*
__EOF__
{code}
Format Partition:
*With mkfs.ext4 1.43, we need to make sure metadata_csum and 64bit are disabled.*
As U-Boot CAN NOT currently handle reading files with these newer ext4 options and so Debian 8 (armel/armhf) and Ubuntu 16.04 (armhf) fsck tools will operate correctly.
{code:title=mkfs.ext4 -V}
sudo mkfs.ext4 -V
mke2fs 1.43-WIP (15-Mar-2016)
        Using EXT2FS Library version 1.43-WIP
{code}
 
{code:title=mkfs.ext4 >= 1.43}
for: DISK=/dev/mmcblk0
sudo mkfs.ext4 -L rootfs -O ^metadata_csum,^64bit ${DISK}p1
 
for: DISK=/dev/sdX
sudo mkfs.ext4 -L rootfs -O ^metadata_csum,^64bit ${DISK}1
{code}
{code:title=mkfs.ext4 <= 1.42}
for: DISK=/dev/mmcblk0
sudo mkfs.ext4 -L rootfs ${DISK}p1
 
for: DISK=/dev/sdX
sudo mkfs.ext4 -L rootfs ${DISK}1
{code}
Mount Partition:
*On most systems these partitions may will be auto-mounted...*
{code}
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/
{code}
 
h3. Backup Bootloader
This version of MLO/u-boot.img will be used on the "eMMC" flasher script on this page.
{code:title=~/}
sudo mkdir -p /media/rootfs/opt/backup/uboot/
sudo cp -v ./u-boot/MLO /media/rootfs/opt/backup/uboot/
sudo cp -v ./u-boot/u-boot.img /media/rootfs/opt/backup/uboot/
{code}
 
h3. Dealing with old Bootloader in eMMC
If you don't want to clear out the old Bootloader in eMMC add this uEnv.txt to /media/rootfs/
{code:title=~/uEnv.txt}
##This will work with: Angstrom's 2013.06.20 u-boot.
 
loadaddr=0x82000000
fdtaddr=0x88000000
rdaddr=0x88080000

uenvcmd=run loadall; run mmcargs; bootz ${loadaddr} - ${fdtaddr};
{code}
 
{code:title=~/}
sudo cp -v ./uEnv.txt /media/rootfs/
{code}
 
h1. Install Kernel and Root File System
