wayland - weston - and framebuffer

[Thilo Cestonaro]

Hey!

I'm totaly new to wayland and weston, so please forgive me if I ask 
silly questions!

I want to run the wayland compositor "weston" on a TI AM335x with no 
graphic acceleration.
So framebuffer only, no opengl or something like that.

I succeeded in compiling libwayland and weston with FBDEV as compositor 
and the weston-tablet-shell.

Now when I try to start weston via UART connection and the command:

openvt -c 7 -w -v -- weston --tty=/dev/tty7 --device=/dev/fb0 
--log=/home/root/weston.log

I get the following logging output:

----------------

For me everything looks fine! (The INFO output was added by me to look 
if weston runs till this point)
But why does weston then end with the SIGSEGV? Doesn't it have anything 
to do?
I thought the weston-tablet-shell should be the session executable, 
right?

Any hints how I can debug further or what I do wrong?

I appended the weston.ini which is placed in /home/root/.config/

Any help is appreciated!

Regards!
