I have a MK70 board which is designed by us with Micron DDR2 been in production for some time and we are getting a higher number of fallouts ( 10%) from production . when we investigated it the problem seems like while booting the LCD  shows the bootloader version and all then suddenly the board goes blank until next powercycle , when we probed the DDR2 clock it  shows 120MHz instead of 150MHz which we have configured for , the DDR2 clock always @ 120Mhz even during the LCD screen is present , any clues /suggetions to try with .
