[meta-freescale] Weston hangs the system on iMX6

[Keskinarkaus, Teemu]

Seems that I was able to get the Weston running after disabling EGL. For some reason EGL causes system to hang. Also seems that disabling EGL didn’t fix the problem. System still hangs when exiting any graphical application. Also disabling EGL means that HW acceleration is disabled as well so it’s not real solution anyway.

What image I need to build to get those samples being built? Or are they available somewhere for download? It’s been awhile since I’ve last time worked on unmodified Yocto.

GPU driver in Wayland image also support EGL-FB as well. Can you please try with any of the basic GLES application. this is just to makesure whether GPU setup correctly.
You can find few presbuilt samples from /opt/viv_samples/vdk/... provided you need to include to rootfs using local.conf

Hi,

I’ve successfully used Weston on iMX6 SabreSD board. Now we have our own custom board (based on SabreSD) and I’m trying to start Weston it just hangs the whole system.

The main difference between SabreSD and our hw is that our HW has 2GB RAM where as SabreSD has only 1GB. I’m puzzled because the graphical stuff is mostly inside the CPU so I’m leaning on the assumption that it’s not HW fault (unless it’s the 2GB vs. 1GB problem.). Memory should be configured okay because system is stable and doesn’t crash on any other way. I can also see normal text login on screen so graphics work at some level at least.

Any ideas what could be wrong? I’ll put it here first since this is probably imx6 issue more than Wayland.

This is the log I get. It always ends at the same spot and system is completely gone. No serial console no responses from Ethernet either etc..
