Hi Eric, Otavio,
I'm afraid I need a little more help....
I'm quite new to yocto and as a result I find it difficult to get results.

what I've done so far:

I set-up the fsl-community-bsp-base 
<https://github.com/Freescale/fsl-community-bsp-base> repo for my 
I added the meta-qt5 layer from the github repository (and adjusted my 
I applied the patch of Vol 77 of the ML on meta-fsl-arm.
I modified a core-image-minimal recepe to build qtbase qtbase-tools and 

when I build this image, the build proceeds fine, however the resulting 
image contains version 5.0.1 of QT for opengl Desktop (!?)
(according to the do_configure logfile for qtbase)

In volume 78 of the ML, Eric mentions "cherry-pick e7a477a"
I 'm afraid don't know how. I tried 'git cherry-pick e7a477a' on the 
meta-qt5 repo, but this results in:
fatal: ambiguous argument 'e7a477a': unknown revision or path not in the 
working tree.

According to the same mail I also should apply the patches from
Then, after setting QT version 5.0.2 in conf/distro/include/qt5-versions.inc
I should be able to build a eglfs supporting version of qt5?

If I get the last part right, the only thing I need help with is the 
cherry-picking part...
