Hello Yang Jiao,

It seems that there are problems when u-boot tries to reach the PMIC. It seems that you are using U-Boot 2016.03-dirty. Which BSP are you using with the board? I would recommend trying with the BSP Releases U-Boot versions. For example the U-Boot version from the L4.1.15 release is v2015.04.

Thank you very much,I follow the net link :

Don't show any error or mistake when compile.

I will try use other uboot version.
