I am using IMX6ul processor with PMIC PF3000A3. We are facing below mentioned issue:

1. There is no supply available for processor including VDD_SNVS_IN.

2. There is a pull up (from an always ON supply) connected on a SNVS powered pin.

3. With out powering up the processor we are getting 2.6V on VDD_SNVS_IN .


In this case if I connect a always ON supply to VDD_SNVS_IN , then we are not able to turn the processor ON once the processor goes into power off until we remove power from VDD_SNVS_IN as well.


Some one please suggest what could be the possible cause of this issue and how we should solve this.
