Hi all,


I make my own buildroot system for wandboard quad with the hfp linaro 2014.05 toolchain ( in buildroot I enabled "Enable NEON SIMD extension support" end the Floating point strategy (VFPv3-D16) ).

I used:

     - kernel 3.10.17 GA

     - gpu-viv-bin-mx6q-3.10.17-1.0.0-hfp.bin or gpu-viv-bin-mx6q-3.10.17-1.0.0-beta-hfp.bin

When I test the gpu example es20/vv_launcher or the Qt example Cinematic Experience I obtain a corrupted image: black and white image stretched ( it cross the display from right to left ) with vertical space line. The same problem with HDMI output or LCD output.

The framebuffer work correctly with the linux logo and psplash.

Where is the problem ?

Thanks and regards
