Hi Tony, I eventually managed to enter retention :))
I did the following changes: 1. added CONFIG_SUSPEND (though I do not use suspend/resume but only cpuidle, it seems to have some effect, I think without it the wakeup in console did not function correctly. 2. enabled sleep for all uart not just the console uart (as I did at first) 3. uart rx was configured as wakeup source Than I can see that cpu0/state4/time is incremented. As I understand state4 is retention in OMAP3530. The only bit strange thing is that I still see picture in screen. I wander how omap can enter retention can be while screen is on. Thanks very much for your assistance, Ran -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
