Hi all,

     Recently, I want to boot up my system via detect ONOFF pin status. But I always get a lot of suggestions by detecting SNVS register value.


I tried to get SNVS_LP and SNVS_HP content during change ONOFF pin but these registers doesn't get any modification.


Is there anything idea for booting-up system by using ONOFF pin detect?


By the way, I want to implement this method into u-boot period. Is it possible?
