Install Images

• Unmount all eMMC partitions:

root@cl-ramdisk:~# umount -l /dev/mmcblk0p*

• Clean up the eMMC flash:

root@cl-ramdisk:~# dd if=/dev/zero of=/dev/mmcblk0 bs=1M count=1
root@cl-ramdisk:~# hdparm -z /dev/mmcblk0

• Create two partitions for the Linux kernel (EXT2 100M) and root file system (EXT4 the rest of the disk) on the eMMC flash:

root@cl-ramdisk:~# echo -e "n\np\n1\n\n+100M\nn\np\n2\n\n\nw\neof\n" | fdisk /dev/mmcblk0

• Format the first partition with EXT2 file system:

root@cl-ramdisk:~# mkfs.ext2 -L boot /dev/mmcblk0p1

• Format the second partition with EXT4 file system:

root@cl-ramdisk:~# mkfs.ext4 -L rootfs /dev/mmcblk0p2

• Mount both partitions:

root@cl-ramdisk:~# mkdir -p /media/boot && mount /dev/mmcblk0p1 /media/boot
root@cl-ramdisk:~# mkdir -p /media/rootfs && mount /dev/mmcblk0p2 /media/rootfs

• Copy zImage-cl-som-am57x and *.dtb to the first (EXT2) partition:

root@cl-ramdisk:~# cp /media/install/zImage-cl-som-am57x /media/install/*.dtb /media/boot && sync

• Extract the content of rootfs.tar.bz2 onto the second partition:

root@cl-ramdisk:~# tar --numeric-owner -xpf /media/install/rootfs.tar.bz2 -C /media/rootfs && sync

• Unmount both partitions:

root@cl-ramdisk:~# umount /dev/mmcblk0p1
root@cl-ramdisk:~# umount /dev/mmcblk0p2
