Beagleboard and Linux tips
« on: March 05, 2012, 09:34:11 PM »
Hi all, I'm running ubuntu 11.10 on a beagleboard and doing some image processing from a webcam with OpenCV with a C++ app I have written. It works well on the laptop it was developed on but it's a bit slow on the beagleboard so I'm trying to optimize things so it'll run smoother. I would also like to optimize the boot time of Ubuntu on the BB.

My question is what are the major things I can do? Right now I'm thinking disabling the GUI/HDMI out would be a big help so what's the best way to do that? I'm logging in over a serial connection so I'm not using any video output of the BB.

Also, is it possible to disable the network manager entirely or any other services that I most likely wont need to help speed up the boot process?

Maybe I should try running a lighter version of ubuntu altogther? Any help would be much appreciated.

Thanks!

explains how to set 11.10 to boot into a terminal. I think this stops xserver from starting, but you may want to double check.

If you use the ubuntu images that are in the tutorials, the GUI shouldn't even be enabled... Among other things, you can make OpenCV run a lot faster by dropping the resolution and disabling JPEG processing (raw images only) when you compile it.
