Can I use the gpu-viv-bin-mx6q-3.5.7-1.0.0-hfp.bin with the kernel version
3.0.35  ?

Dear Eric,

many thanks for the suggestions.

I use the wandboard kernel version 3.0.35_4.1.0.
I have apply your patch in my buildroot version and now with the linaro hf
toolchain the gpu-viv-bin-mx6q examples work correctly.
Unfortunately qmlscene exit without any message (both console and fb). Qt5
work only with sf ?

Why the patch is not present in the last buildroot version 14.02 ?

Regards,
Massimiliano.

Dear,

I have some problem to obtain a buildroot with Qt5 and gpu-viv-bin-mx6q.
Where is the correct combination of toolchain and floating point strategy ?

I try some combination of toolchains with the last stable version of
buildroot (2013.11).

- If I use the last codebanch toolchain the gpu-viv-bin-mx6q examples and
the Qt5 qmlscene crash with segmentation fault.
- If I use the last buildroot linaro toolchain 4.8-2013.09, the system not
start because the kernel is to old ( 3.0.35 ).
- If I use the toolchain linaro-4.7-2013.01 the Qt5 qmlscene exit without
message and gpu-viv-bin-mx6q examples not start with the message program
not found.

Best Regards,
Massimiliano Marretta
