Hi Piotr, Please make sure you have the latest series, the 02 was modified actually, and is different from what you have. If meta-raspberrypi was changed since I sent the patch, then there might be some need to rebase it. Dear list, do you need me to send a v3 taking into account the latest modifications of the meta-raspberrypi master, if any? The other patch threads, that are needed, are: 1. [yocto][meta-raspberrypi][PATCH v3 0/5] Support for .dtbo files for dtb overlays, required by kernels 4.4.6+ 2. [yocto][PATCH v2 0/1] Support for .dtbo files for dtb overlays 3. [OE-core][mesa][PATCH v2 0/1] Fix mesa_populate_packages() when dri is disabled [I believe Ross Burton has modified the original one to use oe.path.join() when committing it]
To be more specific, I will most likely start by fixing gst-omx (which currently wants to use userland on RPI), then go for omxplayer.

There were issues with patches 02, 07 and 12. 02- due to different overlay naming (overlays/vc4-kms-v3d-overlay.dtb instead of overlays/vc4-kms-v3d.dtbo) and 07 and 12 due to bump of linux-raspberrypi from 4.4.8 to 4.4.9 (on master). Now I see that 02 whas not necessary- I just missed the patch you provided earlier. > 3.

Ok. I didn't know. Can you confirm that I have the right patches? Patch for meta is from thread "[yocto] [PATCH v2 0/1] Support for .dtbo files for dtb overlays"? Patch for meta-raspberrypi is "[yocto] [meta-raspberrypi][PATCH 0/8] Support for vc4 graphics driver"? Patch for mesa is part of those patches above? > I'll take a look at the omxplayer issue as soon as I can, in the > meanwhile I recommend to not use it... This would be great.
