Yeah, building a full image (image-full-galileo target) doesn't produce necessary files for creating a firmware package, you need to build an SPI image specifically (image-spi-galileo target).

I had no problems with that. That may be distro-dependant though and sensitive to tools/libraries being "too new" on some. I use OpenSUSE 12.3 without any problems, what's yours?
