Wake up Time from S3 - ktc - 03-18-2016
I don't have access to a board yet but I am very curious about one aspect of the platform.
I have an application that require low power and I need to put Pine64 into sleep most of the time. (S3). Once in a while, it needs to wake up and do some math calculations and go back to sleep.
What type of S3 to active timing I should expect? I can optimize the Kernel such that it only has what I need. (No Display, Camera etc.)
Thx

S3 sleep state it is only intel chips.
A64 Soc, haven't got S3 sleep mode.
the Pmic can put the Soc in sleep mode, and wakeup mode.

I see. I studied the AXP803 datasheet and I see that it is possible to trigger a sleep/wake up functionality. I have a few questions:
- Is the A64 driver for this already available? (i.e. using Sleep/Wake up functionality of AXP803)
- Does the A64 doing STR (Save to Ram) in Sleep Mode?
- What type of Wake up time I should expect?

The A64 can enter in deep-sleep mode.
