as stated in the release note :
http://freescale.github.io/doc/release-notes/1.7/index.html#document-known-issues
Hob is known to not work with with FSL Community BSP. Some of known
issues are problems generating the SD Card images and handling the GPU
drivers.

So you should better use directly bitbake instead of fighting with hob.
