After build the yocto raspberrypi image, sth goes wrong!

The yocto project testing:

"bitbake" the poky distribution with meta-raspberrypi layer for raspberrypi2 B+ board.

After I finished the build process successfully,

I use the following command to write the sd card

    "sudo dd if=tmp/deploy/images/raspberrypi2/rpi-hwup-image-raspberrypi2.rpi-sdimg of=/dev/sdb bs=1M"

Then  insert the sd card, something goes wrong with the boot process, it cannot boot with normal stuff.

Picture of the problems are as follows:
