Part Number: DLPC2607
Other Parts Discussed in Thread: DLPDLCR2000EVM, TIDA-01473

I tried setting the solution from the linked thread:

echo 48 > /sys/class/gpio/export

echo out > /sys/class/gpio/gpio48/direction

echo 1 > /sys/class/gpio/gpio48/value

but it still doesnt come up, also my output from:

root@beaglebone:~# i2cdetect -r 2
WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will probe file /dev/i2c-2 using read byte commands.

the display works if it is turned on standalone, does someone have any idea how to

    how can i know if drivers are being loaded?

    Im using the right image, it even worked once but then stopped working again.

    When i turn it on without BBBW it shows the splash screen...

    Glauber,

    Welcome to the E2E forums, and thanks for your interest in our DLP technology. Another user has posted a similar question so I will copy my response from there.

    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/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

    It seems like there is a transition in place in what regards to cape overlays, and they are transitioning from kernel overlays to uboot overlays, and DLPDLCR2000EVM overlay is a kernel one, are there any plans from TI to update it? I couldnt be able to properly make it work yet. Is there any simple way to manually turn the board on? I mean by wiring to P2_15...

    i cant get it to set the pin:

    Glauber,

    What caused the board to burn out? Do you know which components in particular were damaged? If possible I'd like to explore the issue further. Thanks!

    Best Regards,

    Philippe Dollo

    The board has a bit of poor isolation i think, but the exact steps i did to burn it out was connected a jumper from r3 innermost plug to p2_6 so i could feed it from bbbw, then i connected the other r3 pin on the p2_2, cause i thought that it could be a power related problem, but when i plugged the 5v power supply on the bbbw the board started to smoke and it was already too late, i think it damaged the optical engine so it is pretty broken i think...

    Glauber,

    What do you mean by R3? R3 on the board is tied to the DMD clock, which is not related to power.

    There is a jumper tied to the power supply that you may be able to use to connect the systems to the same rail if you have a second system. To ensure you don't hook up any rails improperly, you may want to consult the reference design (TIDA-01473) schematic:
    www.ti.com/.../TIDA-01473
    www.ti.com/.../tidrs01.pdf

    I am sorry about the damage to your system. If it is possible, I recommend seeking assistance from TI support regarding your damaged unit:

    Best Regards,
    Philippe Dollo
