There is some ways to run a rootfs from a device, it depends in the device, if it can be flashed with its own bootloader or if a bootloader can be ran from a pre-installed winCE. In this case we will prepare the media, which will be the same for both cases (most bootloaders run the second ext2 partition, but if this isn't your case and your flashed bootloader boots the first partition, you can avoid the creation of the vfat partition). In this case, in the vfat partition must be at least the bootloader, the config file for it and a zImage (may be an initrd too to boot from it instead of booting from the rootfs). TODO: Here we provide at this moment the rootfs, but may be in a future we will provided a vfat release for devices (or may be the way to build it) to boot CRUX-ARM from winCE.
