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

Subject: [PATCH 1/1] udev-seat: restrict udev enumeration to card0
In case of separate GPU and Display devices as found in embedded systems, we
could have modeset node and render node controlled by different drivers.
There is a distinct possibility that udev enumeration returns the DRM device
corresponding to render node as the primary DRM device.
Obviously, modeset operations cannot be done on the GPU DRM device.
Restrict the udev enumeration to card0 and ensure that DRM device corresponding
to display is returned as the primary DRM device.

Subject: [PATCH 2/4] Weston: Allow visual_id to be 0
The inquiry of visual id from egl API eglGetConfigAttrib(EGL_NATIVE_VISUAL_ID)
is an optional feature. The visual id will be set to 0 if this feature is
not supported. Therefore, the return condition @function match_config_to_visual()
should be (id == visual_id || id == 0) instead of (id == visual_id)

Adam,
We just switched from Morty to Rocko as our LTS branch couple months ago and
some features are still missing, while teams are ramping up. This particular
issue requires Weston patching in meta-arago, but Weston 2.0 changed some APIs
and those patches no longer apply. Hopefully we'll be able to resolve this in
the near future.
Since this is specific to meta-arago, please direct any further questions to
the corresponding mailing list at meta-arago@arago-project.org
