Newbie: i.MX6UL & Yocto ...stuck at 'Starting kernel'

I am trying to building an sd card boot image for imx6ul evk. 

The bitbake process went ok (i.e. finished building without any errors)

(kernel used: fsl-arm-yocto-bsp.git -b imx-4.1.15-1.0.0_ga)

(image recipe: fsl-image-qt5)

output: fsl-image-qt5-imx6ulevk.sdcard -> fsl-image-qt5-imx6ulevk-20170131022736.rootfs.sdcard


Stuck at 'Starting kernel' when booting on imx6ul evk. 

I will appreciate any guidance to a solution or resource. 


Below is a screen capture from the boot (serial console)
