Which version BSP are you using?
Sorry for the delayed resp. I am using the u-boot version 2018-01.
I am trying to follow the procedure something similar to one in link MCIMX6ULL-EVK - Linux on ARM - eewiki
I wanted to bringup the mcimx6sll board with latest mainline kernel.
The newest BSP for i.MX6ULL-EVK is L4.9.11_1.0.0, all the i.MX6ULL-EVK board materials are here MCIMX6ULL-EVK|i.MX6ULL Evaluation Kit|NXP . About how to build and download the BSP you can refer to the document i.MX_Yocto_Project_User's_Guide in nxp website.
Hope this can do help for you
Have a nice day
