    Om on BeagleBoard XM

    I have ubuntu 10.10 netbook running on my BeagleBoard XM. I trying to run OpenMobile but i get a warning about software rendering. I believe that I installed the SGX video drivers ok but this is the only thing i have to test them. This is probably not an OpenMobile question but i thought someone might have some advice.

    I'm not familiar with your setup but it seems to be some info here: https://code.google.com/p/beagleboar...XunderAngstrom
    I don't know if this is relevant for you though.

    The message about software rendering indicates that your video drivers doesn't properly support opengl.
    Failure is not an option...

    Can you post the output from glxinfo? that should narrow down if its an OM issue or an install issue. Also, if you have it available a Debug log would help

    Here is the output from glx info..... http://pastebin.com/rTttEAAH . (Looks Good)
    Here is the debut output....... http://pastebin.com/RwAQwDwy . (Looks fishy, but i cant tell)

    The OpenMobile team is the best around. You all are always on top of what is going on in the forms. Keep up the good work and you all rock!

    smp, can you give some feedback on how the Beagleboard XM feels? Its one tidy little package, and I know that was one option for embedded use that was being tossed around as an alternative to the igepv2 that others are trying.

    Have you tried using it as a general use linux box at all? Just want to see how it feels response-wise.

    The boot times are a little slow but it is a zippy little computer. Im running the netbook version of Ubuntu Maverick 10.10 and im trying to setup OpenMobile for my car pc frontend. I have it hooked up to a 20" monitor with a bluetooth mouse and keyboard. I have been working back and forth between the synaptic package manager, terminal, and the chromium browser. Wifi is connected over USB and also works great. Jumping between these is a pretty quick development environment. OpenMobile runs super slow but i believe its related to my problem above.

    So to answer your question about being a general usage linux box: for email, browsing, and music it is all good. Video i haven't had a chance to look into yet.

    Thats exactly the kind of feedback I was after!

    It's good to see that these little embedded systems are really picking up the pace. I think they are the way forward for a lot of carPC systems, excepting the real high power requirements. They are small, low power, but packed with features.

    Keep us updated on your progress, we are all looking forward to seeing how you go with OM on the Beagleboard.

    As long as your video player supports hardware acceleration you should be able to do 720p video with only 10-20%CPU.

    Hmm.... so the Embedded: True part means OM is detecting OpenGL ES support but the Vendor String and Graphics card string shows its not using it its using the software renderer. I'm 90% sure that we should get a Version Srting Starting with "OpenGL ES" which makes me think maybe glxinfo doesn't query gl es? I really am not 100% sure and google has nothing since this is kind of a new topic.

    The only thing I can guess is that linux reports an Open GL renderer (which is software) and an Open GL ES renderer (which is hardware). Normally we favor the full open gl version but I think on linux i'm going to flip that. See if rev 594 works any better.

    Theres 4 steps to graphics on an embedded platform:

    1. Initialize the graphics card
    2. Create a graphics context
    3. Create a graphics window
    4. Draw stuff


    Looks like things die on step 3..but at least were working with the embedded framework. I'm submitting the error upstream and hopefully someone can chime in with a cause.
