Hello,
i am currently working on a BSP for yocto in order to support a custom
PowerPC board. In the meantime, i have setup all the config to generate a
properly running 3.14 kernel and devicetree but still have some issues with
the rootfs that is produced by yocto. I chose cpio.gz as image format for
the rootfs which is converted via the u-boot mkimage-tool to a compatible
.uRamdisk image.
I already tested the kernel with a rootfs image which was not generated by
yocto and it works fine.
Unfortunately, the yocto generated image seems to have problems with Init
(target is core-image-minimal, my bsp doesn't modify anything except adding
support for the target board by specifying kernel config and devicetree).
Here you can see the kernel log at the point where init seems to fail:
console [netcon0] enabled
netconsole: network logging started

Have you checked that /dev is mounted and udev is running?
I assume, if i am able to generate a working kernel using yocto, the rootfs
image automatically generated by yocto for target core-image-minimal is not
supposed to fail?
