Reboot period control for i.MX6

[torus1000]

Hi,

I observed VDDs during reboot. Some of them looks not enough OFF time then restart supplying.

Is there any way to stretch OFF time in terms of safe reboot?

I think watchdog control this period.

Where can I find about this in the manual?

Can anyone help me?

Hi torus1000

processor or pmic has not internal hardware ability to stretch OFF time,

it may be done by external circuit, for example increasing RC value

R19,C504 on Sabre schematic SPF-27392 p.21 or using other similar

external circuits for extending pulse, like one shot trigger.

Best regards

igor
