Hi Franc,

at the end of the video, you can find a reference:


which points to an article about our work related to TrustZone:


The article describes in depth, what was done to enable Genode to run
Linux in the "normal world" of ARM's TrustZone. It is also described
what kind of modifications were made with respect to Linux, how it
interacts with the secure side, and how device emulation works in
general. Moreover, the article references a patch including all
modifications of the Linux kernel, and the Genode branch that can be
used to build the demo on your own.

If you have questions beyond the scope of the article regarding
TrustZone within Genode, please feel free to ask.
