imx6ul evk - suspend-on-ram consumption

Hi,

 

we are making some power consumption tests on the imx6ul evaluation board, and we found something which seems a bit odd. When the board enter the "suspend-on-ram" mode, the total consumption of the board goes from 150 mA to 50 mA.

 

50mA seems quite a lot for this mode. Do we have to modify anything to optimize the power consumption when in deep-sleep mode?

 

I read the application note AN5170 (http://cache.freescale.com/files/32bit/doc/app_note/AN5170.pdf?pspll=1 ), and the results are very different.
