    Has anyone managed to get OpenGL to run on MX31L or MX31?
    We have MX31L and a compatible Linux BSP, but have had trouble tracking down the drivers to enable the hardware acceleration with GPL.
    Any success, or failure stories would be much appreciated.

    Thank you.

    The MX31L (note the 'L') DOES NOT have a powerVR hardware acceleration. Only the MX31.

    Correction, we have a MX31 LiteKit from LogicPD, I believe the chip is still MX31.

    DrO. Can you be a little more detailed? Do you mean the drivers come with the Freescale ADS BSP? I'm not sure what you mean by LTIB..

    Update: The driver is available on Freescale BSP and can be included as a module by activating the GX200-BU-98000 package from LTIB.
    Next is getting it to work...

    While we are here, has anyone found stability problems with this driver?

    has anyone been able to force this driver into 24 bit mode?

    there is nothing to getting it to work.
    once the driver is selected from ltib, locate in the filesystem:
    /etc/init.d/rc.pvr
    execute that script to load the modules.

    once loaded you can execute your OpenGL ES code.
    there are some examples and stuff located in the SDK.

    I think I downloaded the SDK from them directly.

    works well, runs pretty good once loaded it runs fast and stable.
    but every now and then, when starting a cold machine and starting the application locks the system.

    for now I am blaming this driver
    I am confident there is a problem or two left in it.
    and the one that kills me is intermittent system lockup.

    if you unload the driver, and try to reload it that can cause problems sometimes as well.
