I downloaded Fedora-Minimal-armhfp-rawhide-20150703-sda.raw.xz
and wrote it to a uSD card.

I am a bit unsure of how to install u-boot into the image,
but I found some instructions at https://github.com/oneru/utilite
that looked promising.

The steps I used (where /dev/sdf is the uSD card):

dd if=/dev/zero count=500 bs=1K | tr '\000' '\377' > cm-fx6-firmware
dd if=SPL of=cm-fx6-firmware bs=1K seek=1 conv=notrunc
dd if=u-boot.img of=cm-fx6-firmware bs=1K seek=64 conv=notrunc
dd if=cm-fx6-firmware of=/dev/sdf bs=1K skip=1 seek=1 oflag=dsync

That does boot into u-boot, but the boot sequence hangs before
u-boot prints its command prompt.  Here is what I get:

U-Boot SPL 2015.07-rc3 (Jul 03 2015 - 01:16:44)
Booting from MMC


U-Boot 2015.07-rc3 (Jul 03 2015 - 01:16:44 +0000)

CPU:   Freescale i.MX6Q rev1.2 1200 MHz (running at 792 MHz)
Reset cause: POR
Board: CM-FX6
I2C:   ready
DRAM:  2 GiB
NAND:  0 MiB
MMC:   FSL_SDHC: 0, FSL_SDHC: 1, FSL_SDHC: 2
SF: Detected SST25VF016B with page size 256 Bytes, erase size 4 KiB, total 2 MiB
auto-detected panel HDMI
Display: HDMI (1024x768)

I also see a very garbled Fedora logo on the HDMI output.

Did I use the correct commands to install u-boot onto the uSD?
