hi ,

I have a imx6slevk board ,use yocto L4.1.15_2.1.0-ga.

I set a gpio to pullup state.

In  standby mode ,the pullup can keep. mem mode the pullup can't keep.

Is there any way to achieve mem mode keep the gpio pullup state?

Hello,

 

  Mem (suspend to RAM) mode maps to DORMANT mode, meaning main i.MX6

power is off. Therefore internal i.MX6 pull up settings cannot be keep.

 

Have a great day,

Yuri
