    Hello Raja,

    Could you try starting the test by doing "sudo python MplayerTest.py". It looks like some of the errors you are getting are do to incorrect permissions. Let me know if this works.

    Thanks,
    Kyle

    Raja,

    Thanks for taking an interest in our DLP products.

    First off, it would appear that you are having permissions errors, but not just in the python execution. When you are extracting the DLP lightcrafter library using "tar -xvf dlp_light crafter-1.0.19.tar.gz" you get permissions errors and failure as well. I recommend you repeat the steps that gave you these errors (including the tar command) using the sudo prefix to ensure that you bypass these permissions errors.

    To be on the safe side, I also recommend you update your system using "sudo apt-get update" and "sudo apt-get upgrade" commands in the terminal before attempting to reinstall.

    Let me know if this helps.

    Best Regards,

    Philippe Dollo

    Raja,

    Thanks for your feedback.

    Does the DLPDLCR2000EVM itself work for the basic display functionality? In particular, have you had any issues displaying the BeagleBone desktop on your system? You can manually issue i2c commands to switch to the BeagleBone desktop:

    i2cset -y 2 0x1b 0x0b 0x00 0x00 0x00 0x00 i
    i2cset -y 2 0x1b 0x0c 0x00 0x00 0x00 0x1b i

    If the above works, you can try manually running the video content using mplayer <file> in terminal. If the system is failing to select the correct video output driver automatically, you may need to specify a working video driver yourself.

    I hope this helps. Let me know where I can help further.

    Best Regards,
    Philippe Dollo
