Linux/DLPDLCR2000EVM: DLPDLCR2000EVM

Part Number: DLPDLCR2000EVM
Other Parts Discussed in Thread: DLPC2607

Tool/software: Linux

Support Path: /Tools & software/Help me with an issue/Design Kits / Evaluation Modules / Boards/Software issue/

I am running a Beaglebone Wireless (BBW) with Debian Image 2017-08-01 (8.9 kernel).  The Display 2000 EVM displays the standalone test pattern, but when attached to the BBW, it displays 00  in the 1b address for i2cdetect command.  The i2cset commands receive a "Write Failed" error.

 

Any suggestions?

    Bill,

    Thanks for your interest in our DLP products.

    Can you provide your i2cdetect output? Also, what happens when you boot the system with the EVM attached (before boot). Does the splash screen come up?

    Let me know such that we can debug this issue further.

    Best Regards,
    Philippe Dollo

    I have resolved the issue with a post: "DLPC2607: DLP® LightCrafter™ Display 2000 Evaluation Module width BeagleBone Black Wireless". Using these commands in sudo mode, I was able to display the splash screen:
    echo 48 > /sys/class/gpio/export
    echo out > /sys/class/gpio/gpio48/direction
    echo 1 > /sys/class/gpio/gpio48/value

    Thank you... Please consider the issue closed.
