    Miroslaw,

    Welcome to the E2E forums, and thanks for your interest in our DLP technology. I do not see anything copied below your post regarding an error log. However, I have a couple suggestions for you.

    I am aware of issues that other users have experienced in booting the DLPDLCR2000EVM cape with the BeagleBone Black Wireless (not the regular BBB). The cape overlay driver packaged with Debian appears to be missing from the Wireless version of the BBB release. You can read more about the cape overlay manager for the BeagleBone here:
    cdn-learn.adafruit.com/.../introduction-to-the-beaglebone-black-device-tree.pdf

    A straightforward workaround for this issue is to manually install the driver on your BeagleBone. Below is a download for the cape overlay file and EEPROM data which can be used to install the driver on any BeagleBone release from scratch:
    /cfs-file/__key/communityserver-discussions-components-files/94/0268.DLPDLCR2000_2D00_00A0.dts

    To install the cape overlay, follow the instructions available at the following page:
    github.com/.../bb.org-overlays

    Let me know if you encounter issues with any of the following steps. After you properly install the cape overlay (and verify it in your cape overlay manager) the system should be able to display the BeagleBone desktop as detailed in the DLPDLCR2000EVM User's Guide.

    I hope this helps.

    Best Regards,
    Philippe Dollo

    Hi Philippe
    At first thank you very much for your help and assistance.
    In spite of installing cape overlay and new kernel for BBBW, DLP2000EVM doesn’t display anything. I know that it possible to resolve this problem – please see groups.google.com/.../
    - but it is not clear for me.
    So, I decided to change my project using a regular BBB where everything is OK, and display IT’s demo (BBBW will be use in another project).
    By the way, I have a special question (request ) for you. Do you have any experiences with cape RS486 CAN for Beaglebone. If it possible to use this cape with BBB and DLP2000EVM together (three devices)?. I would like to use CAN interface in may academic project.
    Thank you in advance

    Miroslaw,


    It's unfortunate that you are running into issues with the BBBW. Once you have properly installed the driver keep in mind that you must issue the appropriate I2C commands to send the system into external display mode. You can also use the cape overlay manager to see if your cape is actually loaded to the system (or if any other capes are conflicting with it). Let me know where you are getting stuck so I can assist further.

    Whether you can use additional capes while the DLP2000 EVM is installed depends on what pinouts each cape requires. For instance, the DLP2000 EVM requires 24-bits of RGB video data plus HSync, Vsync, and some additional power/ground lines (as well as I2C). If the CAN cape that you are looking at does not share any pinouts, then they would be compatible. If they do conflict, you may still be able to get your system to work by rewiring the I/O lines of one of the two capes and adjusting the cape overlay driver accordingly.

    Regards,
    Philippe Dollo
