sleep mode and wake modes..

I have a BBB running headless debian 7.2 from sd card.

I left it up and running last night, when I went to ssh into it this morning it was in a sleep mode or a suspend mode. I want the BBB to stay on all the time and not inter sleep mode at all. I have been searching and searching but really not much out there about debian on BBB.

im not even sure if this is software ie debian… or hardware ie something on the board or in the SOC? I have had the BBB for less than 36 hours so… im sure there are great many things I dont know.

any help or direction woud be great.

Thanks

Umm, it should not have entered suspend mode by default. Which image are
you using (cat /etc/dogtag)

it may have been something external that was connected that cause the sleep mode? im not sure I unpluded everyting, the HDMI and the USB hub with the keyboard and mouse. only thing left was the power cable and the network cable. BBB has been running for the last 36 hours and no sleep mode that I can tell. tho I have not checked the logs.

thanks fo the reply.

Okay, so it's not debian the image i'm developing for beagleboard.org.

You should go ask armhf.com why their image is randomly suspending..

Sorry Robert, I was not aware of your image. I am still quite new to BBB or BeagleBorad and arm in general. I looked all over the beagleboard.org site but only found documentataion for ubuntu, android and angstrom. I didn’t see Debian. I know many or most consiter ubuntu and debian the same… I do want to run headless no matter what and I found angstrom… was not what I I was looking for. I did not want to learn a new operating system. I am familiar with Debian. soo thats why I was looking for a Debian image.

is there a debian headless image on supported on beagleboard.org? if not a could make due with a stable headless ubuntu… but it feels like an imposter (thats a joke) :slight_smile:

at some point I think I will want to compile my own kernel as well. but that is some way down the road. I have not compiled one sense i was in school. even headless there are lots of things I think I could live without for a proxy.

so… is there a headless debian image supported by beagleboard.org?

thanks for putting up with me. there is a lot of information to take in, in a short time.

So the image i'm working on with beagleboard.org is posted here:

This was last week's image.

at some point I think I will want to compile my own kernel as well. but
that is some way down the road. I have not compiled one sense i was in
school. even headless there are lots of things I think I could live without
for a proxy.

so.. is there a headless debian image supported by beagleboard.org?

For a simple headless/server image take a look a this:

Couple different install types, depending on which board you have from
beagleboard.org

Robert, do these images support keepalive on network connections? I am running your 1-29-14 image (SD version) and am unable to keep either my Ethernet or wifi connections alive for more than a few hours, despite pinging out once a minute on both ports. I’ve played with the tcp_keepalive_* and have turned power management off, but stil no joy in what I want to be a reliable headless application.

Robert,

I’m sorry to trouble you. Have you succesfully built an image with power management? I actually am looking for something that will go into low frequency mode or standby when I am not taking measurements (sleep for 5 minutes, wake for 1). Any solutions?
Thank you for all of your hard work!
