Hi all，

Our customized board cannot power up when press the ONOFF(button) for long time(time >6s).

why?? Could you give me some reasons? Is it a bug for this SoC?

3Q!

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
