Hi,

I am using AM437x in one of my application. I am planning to use different power modes to save battery power.

I want to know the time required to switch from low power modes to active mode.

Standby mode to Active mode
Deep sleep mode to Active mode

Any information about mode switch timing is highly appreciated.

Hi Biser,
Thanks for your prompt reply.

But i didn't found any timing information for Deep sleep mode to Active mode on above link and We believe that deep sleep mode to active mode transition will take more time than standby mode to active mode transition. So can you please provide us information for switching time for deep sleep mode to active mode.

I also want to know the switching time for Active mode to Low power mode.
We are planning to use AM437x processor for image capturing with 5 frames / Sec. So timing info is very crucial for us for Power saving.

At this moment these are the only timing measurements available.

Deep Sleep = Suspend in Linux terms.
