That's a detail, but the commit log should be wrapped to 80 columns.

So maybe you should build the host-dfu-util package of Buildroot by
selecting it in the Buildroot defconfig, and use it here?

Which rootfs file? The tarball or the ext2 one?

Maybe:

Using Bluetooth
===============

Enable the bluez_utils package, and then:

$ hciattach /dev/ttymxc4 any
$ hciconfig hci0 up

Of course, make sure you're really talking about bluez_utils or
bluez_utils5, we have two separate packages in Buildroot.

Could you take into account those minor comments, and send an updated
version?

Thanks!
