Please look into below mail thread on the PM off mode support in l-o list. http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg08968.html If you are trying it on SDP , use u-boot mentioned in the above link. use below settings before running echo mem > /sys/power/state for off mode. echo 1 > /sys/power/clocks_off_while_idle echo 1 > /sys/power/voltage_off_while_idle echo 1 > /sys/power/enable_off_mode I tried it on my SDP with omap_3430sdp_min_defconfig, I am seeing all the domains entering to OFF mode. thanks Ramesh Gupta G -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
