DLP4500: Board Stuck in Pattern Mode, GUI Does Not Detect Board

Abhijan Wasti

Part Number: DLP4500

Hi,

I am trying to configure my DLP4500 with the LightCrafter 4500 Control Software. I set up my pattern sequence, saved it as a solution, and created a new firmware with this solution so that I don't have to set my sequence again. I uploaded this firmware on the projector and now it automatically enters pattern mode and is projecting the pattern. The problem is that the LightCrafter 4500 Control Software can no longer detect the projector.

I have tried:

1) Resetting the projector (pressing the reset button on the board)

2) Restarting the projector (plugging it on and off again)

3) Putting the projector in Standby mode and back

4) Unplugging and replugging my USB connection

5) Closing the Control Software and opening it again.

Nothing has worked so far.

Here's my .ini file for reference:

In case you want to try running it yourself to see if you can replicate the issue, you can find the firmware here: drive.google.com/.../1NReK4L5ij6NxpKnonPOWuN65_7C_ofqG

The only thing I think I might have done to break it is to automatically enter pattern mode. What could be the issue and how do I solve it?

    Hello Abhijan,

    Welcome back to the E2E forum. Thank you for your continued business!

    Can you reflash the original firmware onto your board? Can the GUI still not detect the board?

    Best,

    Maxine

    Hi Maxine!

    The computer could detect a USB connection, but the GUI could not find the projector. As a last-ditch effort, I shorted the J18 connectors on board (this enters bootloader mode), and reset the projector (by pressing the reset button on board). This finally worked and now the GUI can communicate with the projector. (After flashing, I removed the connection across J18 to resume normal function)

    I'm still not sure why it was not able to communicate with the computer while in pattern projection mode. After diff checking an original file and this file with the images, I was able to see that the following:

    1) Line:

    DEFAULT.DISPMODE 0x0 ;
DATAPATH.SPLASHATSTARTUPENABLE 0x1 ;

    were changed to
     

    DEFAULT.DISPMODE 0x1 ;
DATAPATH.SPLASHATSTARTUPENABLE 0x0 ;


    2) The following lines were added:
    PERIPHERALS.I2CBUSYGPIO_ENABLE 0x0 ;
PERIPHERALS.I2CBUSYGPIO_SELECT 0x0 ;


    My guess is unsetting the two I2CBUSYGPIO caused it to be irresponsive. Is that correct?

    Hello Abhijan,

    Yes, you are correct. These two registers should be set to 0x1 in order for I2C commands to be sent and received. Do you have any other questions I can help you with?

    Best,

    Maxine
