I am trying to find out why the ON/OFF pin does drive the PMIC_REQ_ON pin low. I have a button to GND connected to the ON/OFF pin on the IMX6D device. In OFF mode and initial power up, the SNVS is at 3.0V provided by a PMIC. When I press the ON/OFF button, I am expecting PMIC_REQ_ON pin to go low so it will turn ON the PMIC. I don't see the PMIC_REQ_ON pin on IMX6 go low after a button press. What are the requirements for the ON/OFF pin and PMIC_REQ_ON to work on initial power up.
Thanks in advance.
