After that set the boot partition from user space using the mmc tool:
(for 'boot0')
target$ mmc bootpart enable 1 0 /dev/mmcblk2
(for 'boot1')
target$ mmc bootpart enable 2 0 /dev/mmcblk2
To disable booting from the eMMC boot partitions simply enter the following command:
target$ mmc bootpart enable 0 0 /dev/mmcblk2
To choose back to the user area u-boot environment:
target$ mmc bootpart enable 7 0 /dev/mmcblk2
Resizing ext4 Root Filesystem
fdisk can be used to expand the root filesystem. The example works for any block device such as eMMC, SD Card, or
hard disk.
Get the current device size:
target$ fdisk -l /dev/mmcblk2
The output looks like:
Disk /dev/mmcblk2: 7264 MB, 7616856064 bytes, 14876672 sectors 116224 cylinders, 4
heads, 32 sectors/track
