Linux system clock when iMX6 is in deepsleep

[sivaraj]

Hi,

I am using iMX6 processor with Linux OS in a project. Can you please let me know whether linux system clock will be running when the iMX6 is in deepsleep mode? If it will not be running, how the system clock will be updated in when the iMX6 wakes up.

Thanks,

Sivaraj

Hello Sivaraj,

Deep sleep mode is implemented in linux, please check 
Chapter 21 Low-level Power Management (PM) Driver of the  Linux Manual for description of Mem (suspend to RAM) mode and AN4509 i.MX 6Dual/6Quad Power Consumption Measurement sect. Deep Sleep Mode

Note, if custom modifications of linux sources are needed, may be recommended
to apply to profesional services or elevate request through local fae channel (project info
may be needed).
