imx6qsabresd hardware gpu acceleration

Hello everyone,

 

I'm trying to build an image according to those parameters :

 

- iMX : MCIMX6Q-SDB

- Using Yocto

- Need of QtWebkit

- Using the hardware GPU acceleration of Vivante

- With Wayland/Weston

- We're using a EETI eGalax Touch Screen for testing

- On a sdcard

 

The actual purpose is to obtain the best performance possible with a HTML5 app... (400/500 FPS would be perfect :-))

 

Here's the problem, nothing is displayed on my screen, it's like the "Vivante driver" stops my weston server (I also tried with x-server, it stops it too).

 

I'm using

 

MACHINE="imx6qsabresd"

DISTRO_FEATURES += " opengl glibc ..."

IMAGE_INSTALL += " qt4-embedded qtwebkit qtwebkit-examples"

"require recipes-graphics/images/core-image-weston.bb"

PREFERRED_PROVIDER_virtual/kernel = "linux-imx"

 

I don't know what I'm doing wrong but nothing is happening on my display.

 

When I try "cat /dev/urandom > /dev/fb0" I get a "No space left on device /dev/fb0".

 

Is there something to change in the "imx6qsabresd.conf" ? Maybe it's a question of partition space in the sdcard ?

 

Thank you,

 

Aïda
