When ruuing mx28_cpu_suspend in sleep.S, and interrupt should wake up the system, but the system already has been poweroff. What's wrong with me? I test with comand "echo mem &gt; /sys/power/state".</P></BODY></HTML> Mon, 06 Aug 2012 03:32:01 GMT https://community.nxp.com/t5/i-MX-Processors/mx28-do-mem-wakeup/m-p/179292#M7353 alex 2012-08-06T03:32:01Z Re: mx28 do_mem wakeup https://community.nxp.com/t5/i-MX-Processors/mx28-do-mem-wakeup/m-p/179293#M7354 <HTML><HEAD></HEAD><BODY><P>Yes, it is impossible to wakeup powered-off CPU by itself.
