Weston problem on parallel lcd display

davideballestre — Fri, 12 May 2023 10:59:37 GMT

Hi,
we are running BSP 5.15.71_2.2.0 on a custom board with a parallel lcd display and imx6dl microprocessor. We are facing a problem with weston surface g2d-renderer. only vertical stripes are visible (see attached image).
It seems a pixel format problem but framebuffer is working well and weston logs are ok.
Without "use-g2d=1" weston fails to start with "failed to create egl surface" (see attached log).
Can you help me?

Thanks

Davide

Hi @davideballestre,

I hope you are doing well

My apology for the delayed response.

Please try to set the bpp value for the Weston to <16> from the device tree.

Thanks & Regards,

Dhruvit Vasavada
