    141 ==== Update Entire Firmware (recommended)
    142 Update the entire device from a Compressed Disk Image. This image includes the partition table, boot firmware, bootloader environment, as well as entire OS and kernel:

    144 Complete Compressed Disk Images are available for download here: [http://dev.gateworks.com/venice/images/]
    145  * Be sure to use one that is compatible with the SoC on your board

     143==== Update OS via Compressed Disk Images
     144A compressed disk image is relatively easy to create and is easy to install on a running board via U-Boot or Linux running from a ramdisk. Assuming boot firmware is booting from another device or hardware partition (ie eMMC boot0 hardware partition) the compressed disk image contains only the disk partition table and OS filesystem partitions.

     174Note that Gateworks used to place boot firmware in the eMMC user partition meaning the compressed disk image would also include the boot firmware. This is now considered 'legacy' but to keep users from bricking boards that still have boot firmware on the eMMC user hardware partition the Gateworks Venice BSP still places imx8mm boot firmware in the compressed disk image.
