Based upon Robert's recent reply here, I'm going to assume that I am not up to the task of trying to figure out how to build a kernel with sleep state enabled (as a BB newbie). What a pity. Now, he does say hibernate and not simply low power state. Hibernating isn't as important as suspending or changing frequency. I'll keep poking around.
<quote> Hello, I'm using the Beaglebone Black with Ubuntu 12.04 (an image based on Robert Nelson's 3.8 Kernel and downloaded from http://www.armhf.com/index.php/boards/beaglebone-black/#precise). What support is there for power saving features? How can I put the machine into a suspend or a hibernate mode? Get it out of said state? I really appreciate your feedback. -David Hi David, Hibernate support does not currently work in any of the existing mainline based kernels for the TI am335x line. When it does work the standard. echo mem > /sys/power/state Will apply. </quote> TAKEN FROM http://eewiki.net/display/linuxonarm/BeagleBone+Black+Comments?focusedCommentId=29884675#comment-29884675 On Friday, March 7, 2014 2:31:33 PM UTC-5, Ruben Kertesz wrote: > > I understand that this question has been asked before in various forms and > apologize to those who think this is a useless question.
