I am running uclinux on a Blackfin 527. I am always in Full On mode of the Blackfin. I would like to lower my power consumption during periods of low activity.
I can't use Sleep mode because I need some CCLKs because my application has to continue running to maintain communications with another system even during inactive times. I may be able to use Active mode. Does uclinux offer support for entering Active mode and then programatically switching back to Full On mode? I only saw linux support for standby (sleep or deep sleep) and for mem (hibernate), both of which would stop CCLK so I can not use them.
