  Hi Zoltan,

  A few comments in addition to Thomas's.

  The kernel config is typically called "linux-<version>.config".  In 
your case, the version is gnublin_support_v1 which is a bit unfortunate, 
so perhaps 3.7 is better.

  (It would be nice if the gnublin kernel tree would tag with e.g. 
v3.7-gnublin-1 instead.)

  It would also be nice if the gnublin kernel tree would contain a 
defconfig for the board, then there's no need to include a custom linux 
config in buildroot.

  It would also be nice if it would follow the stable kernel (currently 
3.7.6 I think).

  Would be nice to mention the SoC used.

  I guess that should be 3.7 (there is no 3.7.0 tag or tarball).

  Tip: if you're not using conversions, cat is generally much more 
efficient than dd:

cat output/images/u-boot.bin > /dev/sdc2
