Unfortunately no. I remember Ronan having weston launched but only
displaying a black screen. This has been corrected but I don't know what
commit fixed it. Ronan, do you remember what was the issue ?

One thing that is important to know: Tizen IVI built with Yocto doesn't
start weston the same way as Tizen IVI because Tizen IVI Yocto is fully
based on Tizen Common Yocto thus work in a similar way (which isn't the
case for Tizen IVI and Tizen Common where the delta between Common and IVI
is more important). For example Tizen IVI Yocto uses tlm (like Tizen
Common) which isn't (or wasn't) the case for Tizen IVI.

IVI Yocto uses the exact same kernel as Tizen Common Yocto. This should be
easy to fix by creating a bbappend to the kernel in the IVI layer to add
the missing patches and modify the configuration.
