David: If you are running "headless", that is, not using the on board video-graphics system, all interaction with the unit is via the console, local or SSH.
In this case, I would use the "console" version as described above. It is about one tenth the size of the version you are using. You will need to install ntp, and disable whatever time system is already present. As well as any time and logging services that you do not use, that you can find. Debian is in transition from using a services management system called "init" to a new system called systemd or "system daemon." Debian 7.8 you are using is a mixture of both. By Debian 8 (jessie) the transition will be complete and is an almost pure systemd environment that will give you a centralized location and command set to view and turn on/off all services, including the recurring time-based ones. Jessie is in test currently, and should be released in the next few months. It is the OS for the new Beaglebone X-15 due out mid-year. They have not yet released a "console" version, but it real close. The other thing that will help is getting rid of the cape-manager system you are using, that is file i/o based. There is a lot of file scanning going on that is not useful in time critical applications. --- Graham == On Sun, Mar 22, 2015 at 8:29 AM, Mike George <[email protected]> wrote: > David: > > On this page: > > http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#BBW. > 2FBBB_.28All_Revs.29 > > they list an alternative console only image: > > https://rcn-ee.com/rootfs/bb.org/release/2015-03-01/ > console/bone-debian-7.8-console-armhf-2015-03-01-2gb.img.xz > > It might be easier starting with that if you don't intend to use graphics. > > Mike > > On 3/22/2015 03:46, David J Taylor wrote: > >> David: >> On the BBB, were you running the fully loaded release, or the minimum >> "console" version of the OS? >> Which specific version of the OS? >> >> Thanks, >> --- Graham >> ================================= >> >> Graham, >> >> The download was: >> >> bone-debian-7.8-lxde-4gb-armhf-2015-03-01-4gb.img.xz (547,024,548 bytes) >> >> which was from the "Recommended Debian Images" from: >> http://beagleboard.org/latest-images.
