AM335x Weston screen is blank



Hello,

I'm using Yocto/Poky Krogoth distribution (version 2.1.2) on BeagleBone Black (rev C) with latest meta-ti layer and fixes from meta-arago-distro for patching weston-1.9.0

When I try to start weston by "weston-launch -- --backend=drm-backend 2>westonlog" weston seems to launch successfully, but my screen does not refresh at all (e.g. I see previous console output).

Here's my weston output (pastebin), dmesg output

What can I do to solve this issue?

Thanks

  • Hi,

    This forum supports only the official TI release: www.ti.com/.../PROCESSOR-SDK-AM335X Can you try with it?
  • Yes, Processor SDK works.
    Anyway, I can't build SDK from sources because Linaro removed old packages, and Arago project build fails with 404 error on binutils.

    Should I ask in meta-ti mailing list instead of E2E?
  • Hi,

    Can you please attach the Weston output & the dmesg log as txt files? I can't access pastebin.

    Best Regards,
    Yordan
