The Galileo board boots off of an SD card that has a special disk

that format via the following steps.
The Galileo board can boot off of either an SD card or USB storage
media that has a special disk layout. The 'wic' tool can be used to
create directly bootable images for either of the two formats via the

Use the wic script to create an SD card image:
$ wic list images
mkgalileodisk Create an Galileo Gen 1/2 disk image
mkgummidisk Create an EFI disk image
galileodisk-sd Create an Galileo Gen 1/2 disk image (SD card)
galileodisk-usb Create an Galileo Gen 1/2 disk image (USB Storage)
mkgummidisk Create an EFI disk image
Assuming you want to boot the 'core-image-minimal' image:
Assuming you want to boot the 'core-image-minimal' image for SD card media:
$ wic create mkgalileodisk -e core-image-minimal
$ wic create galileodisk-sd -e core-image-minimal
If successful, the wic script generates the image and prints its location:
Info: The new image(s) can be found here:
/var/tmp/wic/build/mkgalileodisk-201604211444-mmcblk0.direct
/var/tmp/wic/build/galileodisk-sd-201604211444-mmcblk0.direct
...
Write the output image to an SD Card
$ sudo dd if=/path/to/image/mkgalileodisk-*-mmcblk0.direct of=/dev/your_sd_dev
$ sudo dd if=/path/to/image/galileodisk-sd-*-mmcblk0.direct of=/dev/your_sd_dev
Insert the SD Card into the reference platform and power on.
To create a direct-boot image for USB storage media, simply specify
galileodisk-usb instead of galileodisk-sd in the "wic create ..."
command, then write the output image to USB storage media and boot it.
