Hi, Adam:

The problem shows as the following line.

[19:24:55.055] initializing drm backend
[19:24:55.091] using /dev/dri/card1

The SGX DDK creates another dri-like device as card1, but it should not be used 
as DRM device.

Please apply the following patch to the Weston build.
0001-udev-seat-restrict-udev-enumeration-to-card0.patch.

You may need other patches under 
meta-arago.meta-arago-distro/recipes-graphics/wayland/weston including
0002-Weston-Allow-visual_id-to-be-0.patch

Best regards,

Eric

I spent a bit of time getting the logs:

Any insight as to why this is happening, it would be much appreciated.

Has anyone successfully brought up Weston desktop shell on the current master 
on Beagleboard X15 or AM57xx-EVM? I am having EGL initialization error. I don't 
know if it is something I have mis-configured.
