    29 == Disk Images ==
    30 Gateworks releases disk images that can be easily flashed using the U-Boot Bootloader (see [wiki:newport#serial-ethernet here]). These disk images contain a partition table so they are tailored to the specific eMMC device on the boards they are intended for. Additionally they are configured for a small partition size to keep flash programming time at a minimum. This requires resizing the rootfs partition be resized in order to take advantage of the remaining flash space.
    31 
    32 The script used to create these images can be found on !GitHub [https://github.com/Gateworks/images-newport/raw/master/mkimage here] and an example usage is:
    33 {{{#!bash
    34 sudo ./mkimage xenial-newport 7264 1536 firmware-newport.img xenial-newport.tar.xz linux-newport.tar.xz
    35 }}}
    36  * The user partition of the 8GiB eMMC used on Newport is 7264MB
    37  * We need around 1536MB of partition space for the extracted kernel and root filesystem
    38 
    39 To flash this compressed disk image to a board see [wiki:newport#serial-ethernet here]
    40 
    41 To install the kernel and root filesystem on a removable block storage device see [wiki:linux/blockdev].
     29== Building a Bootable Disk Images ==
     30You will want to build your own Ubuntu disk image if you want control over any of the following:
     31 * contents of root filesystem (packages and configuration) (see [#debootstrap debootsrap below)
     32 * configuration of the Linux kernel (see [wiki:newport/bsp#kernel newport/bsp/kernel])
     33
     34See [wiki:newport/boot#disk-images newpowrt/boot/disk-images] for detailed instructions.
