I.MX7 boot failed

[kennithhsu]

Hi All:

My u-boot version is 2016-03 and kernel version is 4.9，

and my bootargs was setting as below:

setenv bootargs console=ttymxc0,115200 root=/dev/mmcblk0p2 rootwait ro earlyprintk

but the boot process was failed after cpu0  Setting up static identity map.

should I have modified somewhere in my u-boot 2016-03?

the log as below:
