The demo scenario cannot be executed on top of sel4 yet. In our recent
release notes (16.02), where the upgrade to sel4 version 2.1 gets
described, you can find the following paragraph at the end:

"Functionality-wise the update to version 2.1 brings no changes. The
preliminary support is still limited to Genode's most fundamental
mechanisms like the bootstrapping, the creation of protection domains,
the execution of threads, and inter-component communication. User-level
device drivers are not supported yet. Such functional improvements are
scheduled for Genode 16.08."

Due to the lack of user-level device driver support until now, you
cannot start the demo scenario.

That is completely right! Doing 'make prepare' is deprecated since
before the initial port of Genode to sel4. Please use the "prepare_port"
tool for all 3rd party software preparation in Genode's source tree.
