fb is not supported for imx8mqevk in L4.9.51_imx8mq-ga

Hi,

I was trying to build an image to framebuffer with the new release for my imx8mqevk demoboard without luck. The steps I've done:

$ DISTRO=fsl-imx-fb MACHINE=imx8mqevk source fsl-setup-release.sh –b build-fb

$ bitbake imx-gpu-viv

Loading cache: 100% |###################################################################################################################################################| Time: 0:00:01
Loaded 3068 entries from dependency cache.
ERROR: Nothing PROVIDES 'imx-gpu-viv'
ERROR: imx-gpu-viv was skipped: incompatible with machine imx8mqevk (not in COMPATIBLE_MACHINE)
ERROR: imx-gpu-viv was skipped: incompatible with machine imx8mqevk (not in COMPATIBLE_MACHINE)
ERROR: imx-gpu-viv was skipped: You must set MACHINE_SOCARCH_SUFFIX as MACHINE_SOCARCH_FILTER is set for this SoC.

The same steps with the L4.9.51_imx8mq-beta release worked ok.

Any solution?

Thanks!

I've been able to track down the problem to the file:

sources/meta-freescale/conf/machine/include/imx-base.inc

In the previous version this file didn't exist. If I remove that file I can build the image. I guess the mx8 definitions are missing in this file...

There doesn't seem to be framebuffer (or X11) support as per L4.9.51_imx8mq-ga release notes :

No X11 backend is supported in i.MX 8MQuad.
No Frame Buffer backend is supported in i.MX 8MQuad.

The only option is building for wayland, similar question in this thread.

Yes, you're right. Now I've arrived until the cairo recipe building problem like described in the thread you linked.

We'll need to wait to NXP to patch this.

Thanks for your answer.

Are there plans for the bsp to support fbdev or moving to DRM ?
