iMX6 egl corrupted on framebuffer

maxmar — Wed, 20 Aug 2014 07:09:26 GMT

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

Massimiliano

Can you please tell us where do you download the BSP image?, I try it with the Freescale SDP board and Official Freescale image and the test works correctly.

I used the kernel source from github.com/wandboard-org/linux branch wandboard_imx_3.10.17_1.0.0_ga_test

and the gpu driver from http://www.freescale.com/lgfiles/NMG/MAD/YOCTO/gpu-viv-bin-mx6q-3.10.17-1.0.0-hfp.bin

on the Wandboard Quad

No, the project was abandoned.
