Efika MX Smartbook, your first run
Since FreeBSD port currently not require any special features, then it’s possible to boot kernel from original (first) uboot.
- Fetch U-Boot image here http://people.freebsd.org/~ray/u-boot_efiks_mx_smartbook.imx
- Insert unused SD card
- WARNING! Check your /dev/da devices first, to not damage other cards, of SCSI HDD, or USB flash stick. Assuming your unused SD is /dev/da0 dd if=u-boot_efiks_mx_smartbook.imx of=/dev/da0 bs=1k seek=1 conv=sync
- Invert DIP switch under keyboard (1-OFF, 2-OFF, 3-OFF, 4-ON)
- Power up device (Press power button)
If you connect ASIX based USB Ethernet adapter and type “run bsd”, U-Boot will try to assign IP 192.168.10.88 to axe0 and ask efika_mx/kernel.uboot by TFTP on host 192.168.10.90.

Preparing card Assuming you have connected to your PC SD card and it have device name /dev/da0.
# Create MBR partitioning scheme
gpart create -s MBR da0
# Create 128MB fat32 slice
gpart add -t fat32 -i 1 -s 128m da0
# Create space for swap (better at least 1G)
gpart add -t freebsd -i 2 -s 512M da0
# Anything left for FreeBSD filesystems
gpart add -t freebsd -i 3 da0
# BSD partitioning
gpart create -s BSD da0s3
# Give everything to rootfs
gpart add -t freebsd-ufs da0s3
# Done, now mount filesystems
mount -t msdosfs /dev/da0s1 /mnt/imx/dos
mount -t ufs /dev/da0s3a /mnt/imx/ufs
Preparing files for boot No fill with data. We need boot script and kernel.
boot script Create file boot and add following lines to it:
echo Initialize MMC subsystemmmcinit
echo Loading kernel ...
fatload mmc 0 0x91000000 kernel.uboot
echo Start kernel
bootm 0x91000000
Pack script into U-Boot image:
mkimage -T script -d boot boot.scr
