Hi tony
from sect.10.5 ONOFF (Button) IMX6DQRM :
When the chip main power supply is Off, a button press greater in duration than 750
ms asserts an output signal to request power from a power IC to power up the SoC..
Button presses greater than 5 seconds, when the SoC is powered, results in a direct
hardware power down request
It is recommended to check PMIC_ON_REQ signal
and that permanent SNVS voltage is provided to i.MX6.
Best regards
igor
