Hi Shalan

from log "Unable to handle kernel NULL pointer dereference at virtual address"

seems these errors may be related to memory, please run ddr test

i.MX6/7 DDR Stress Test Tool V2.70 

and try with some of nxp linux bsps described on

i.MX 6 / i.MX 7 Series Software and Development Tool|NXP 

Best regards
igor
