Sabresd board repower problem

Question asked by xuegui liu on Feb 15, 2014

Phenomenon: after linux boot up, if power off board,  and repower(time gap enough),   board cannot boot up(no u-boot message printed), but repower again, board can boot up normally. and there is alwaly ok during  u-boot booting when reboot the board via power off / on operation.

 

so i guess there is something wrong related with PMIC(MMPF0100) configuration.  and your suggestion will be appreciated!
