Hello Julien,
I used the kernel config:
http://xenbits.xen.org/people/sstabellini/config-hikey and the source
mentioned in https://wiki.xen.org/wiki/HiKey to build the kernel (I will
call it stabellini kernel). I used the same kernel (stabellini kernel)
to run Android, since I did not had any success with the Android kernel
from the pre-build 96Boards Android image.

I think the stabellini kernel works only with the Linux init system and
not with Android's init stystem. Both init systems are very different
from each other.

I thinks the solution would be to insert some of the Android specific
things in stabellini's kernel config, but I have no idea which one.

My assumptions could be completely wrong.

Best regards
