Does LSDK support LPM20?

I test the power management feature by following "11.1 Power management user manual" of LSDK User Guide 1909 on FRWY-LS1046A board.  But I don't see ASLEEP LED is turned on when I run the following command:

echo 0 > /sys/class/rtc/rtc1/wakealarm && echo +10 > /sys/class/rtc/rtc1/wakealarm && echo mem > /sys/power/state

I expect that LS1046A enters LPM20 state by echo mem > /sys/power/state .  Am I wrong?  If so, how to put LS1046A into LPM20?

 

Best regards,
