Dear NXP,


I got observation when I try to send  suspend-to-ram command ( echo mem > /sys/power/state ) from Android and Linux


Suspend to Ram in Android OS,


      # echo mem > /sys/power/state


      Application Processor going to suspend and resumed automatically


Suspend to Ram in Linux OS,

      L4.14.78 & L4.14.98

      # echo mem > /sys/power/state


      Application Processor going to suspend and wait for user press power key



Will you please give me the configuration or implementation to achieve the Linux level in Android ?




Thanks & Regards,
