Hi,

I dont want use echo mem > /sys/power/state because i cant wakeup system after with a GPIO and how reduce the consumption via software with for example  (reduce the frequency of the CPU and  shutdown the various peripherals)?

how modified mx53_loco.c for to obtaine reduced consumption and which register i must modified? there is an example?

 

For example I'm trying to turn off all clock with CCM_CCGR register, but i dont know how to do..

 

I've inserted this code in my mx53_loco.c:

 

_clk_disable(&pll1_sw_clk) but i have same error...

 

thanks..
