it is not necessary anymore to do the steps for building a u-boot image
manually. In the latest release notes you'll find a section that
describes how to do this automatically when issuing a run script:

  http://genode.org/documentation/release-notes/13.05#TFTP_boot_using_U-Boot

Please, assure to use the latest Genode version, either by cloning
current master branch of the Genode git repository, or by downloading
the lates release. Then do e.g.:
  'RUN_OPT="--target uboot" make run/demo'
in a freshly created build directory, and boot the resulting image at:
  [your_build_directory]/var/run/uImage

To me this indicates that something went wrong when loading the kernel,
please assure to use the way described above. If it nevertheless stucks
at this place, would you please post the whole initial u-boot output in
the first place?

You can always use one and the same uImage to boot it via TFTP, or read
it from sd-card. There is no difference. For information on how to boot
a uImage from sd-card, you might consider the u-boot documentation, or
online references.
