Hi,
I'll do it strictly according to your tutorials(I.MX6Q ASBRE Board for Smart Devices),I met a problem when power on the i.MX6q SABRE Board,The Uboot boot failure, according to the following:

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.
Regards,
