Hi,

 

we are trying to measure power requirements for i.MX6Q system

on SabreSD (Quad).

 

When going to lowest possible power saving mode with Linux

command:


echo mem > /sys/power/state

 

The whole board is still consuming 0,96W (at 5V input). We have

disconnected and disabled all peripherals.

 

We would expect somewhere around 50 mW based on

infomation in your i.MX6 application notes.

 

Why can we achieve lower value than 1W? This is too much.

 

The second problm is it takes around 300 ms to wake up. i.MX6

RM says 10ms.
