    56 == Installing Compressed Disk OS Images
    57 Gateworks releases compressed disk images for various Linux based operating systems that can be easily flashed using the U-Boot Bootloader. These disk images contain a partition table so they are tailored to the specific device size they are intended for. Additionally they are commonly configured for a small partition size to keep flash programming time at a minimum. This requires resizing the rootfs filesystem in order to take advantage of the remaining flash space.

    59 You can install a compressed disk image using the methods described in [wiki:venice/firmware#firmware-update venice/firmware-update]. For example in the bootloader:
    60 {{{#!bash
    61 setenv dev 2 # emmc device; use mmc list to see all mmc devs
    62 tftpboot ${loadaddr} firmware.img.gz && gzwrite mmc ${dev} ${loadaddr} ${filesize}
    63 }}}
    64 
    65 If you are interested in creating a compressed disk image with a custom root filesystem directory/tarball with a kernel and bootscript you can following along the process used in the in the [https://github.com/Gateworks/bsp-venice/blob/master/Makefile Venice BSP makefile]
    66 
    67 If you created a filesystem that did not stretch to the partition it was installed on (as we create a minimally sized filesystem image to fit within the eMMC device for faster programming) you will want to resize it after booting to Linux. This is a one time operation after flashing a compressed disk image and can be done using the 'growpart_once' script that we install on the Ubuntu Root filesystems found in the script [https://github.com/Gateworks/ubuntu-rootfs/blob/master/ubuntu-rootfs.sh here] (search for growpart_once)
    68 
    69 To install the kernel and root filesystem on a removable block storage device see [wiki:linux/blockdev].
