Hi,

I'm trying to integrate Qt5 with Yocto on the Wandboard Dual (i.MX6). I've been following these two tutorials:

http://wiki.wandboard.org/index.php/Getting_started_with_Yocto_on_Wandboard

http://wiki.wandboard.org/index.php/Building_Qt5_using_yocto_on_Wandboard

The problem occurs when I am ready to bitbake the meta-qt5 recipe into the core-image-minimal. I add the recommended features to the local.conf and remove the x11 and wayland components in order to get the eglfs drivers. Then I bitbake core-image-minimal, the bitbake succeeds fine. I then run a dd command to write the core-image-minimal-wandboard-dual.sdcard to my sdcard.

I was curious so I tried replicating those steps and was able to get it to fail on my Wandboard Dual immediately.

There are a LOT of packages added to the image, so I figured that one of them was somehow causing the problem. I started binary searching. After 9 iterations of including/excluding packages from the build, I found that GIT of all things was causing the kernel panic. If you exclude git, then you get a successful boot.

That is just weird. I don't have the time to figure out why this is, but I hope that this helps you.

Finally, upon inserting the sdcard into my wandboard, I boot it up and view the output through serial. The boot fails with a "Kernel panic - not syncing: No init found.".

Here is the log of the first boot: http://pastebin.com/gr8LpMRU

And here is the log of when the board is reset: http://pastebin.com/eauuw3Q2

Does anyone have any idea why this is happening and how I can fix it?

Thank you!
