Disable Automatic Flash Updates

The Versatile Express may automatically overwrite the Linaro images in flash without the following changes.

  • Connect a USB cable to the USB client port (USB-B FlashDrive to PC) on the rear of the unit

  • Plug the USB cable into your host
    • Your host should auto detect the Versatile Express and mount it as a disk drive
  • Navigate to the mounted system and find the config.txt file - it will be in the top level directory
  • Make the following changes/additions to the config.txt file using a text editor

TOTALIMAGES: 0xA                 ;Number of Images (Max : 32) <Add 4 to the value that was here>
