DLP3010EVM-LC: DLP3010

Part Number: DLP3010EVM-LC
Other Parts Discussed in Thread: DLP3010, DLPC3478, DLPC3430

I am attempting to flash an image onto the DLP3010, however I am unable to communicate with the board. I am using "DLP EVM GUI" to interface with the board. The board is powered with a 19V power supply. The board is connected to a laptop using USB and the power switch is in the ON position. The board has LEDs that turn on when connected to the power supply. The message for connection at the bottom of the GUI screen states "Connected, powered off". Attached are screenshots of the main screen and screenshots of the errors we received when attempting to connect the board. If there is any further information needed, please let me know.

    Hello Michael,

    Welcome to the E2E forum and thank you for your interest in DLP® technology.

    Do you see any projected image from the EVM when the power supply is plugged and the switch is ON, even though the EVM status shows Powered off on GUI?

    You should be able to flash the image onto the EVM with power supply and without moving the SW_ONOFF switch via GUI. After programming completed, please move the switch to ON. 

    The latest available GUI version is 3.1.0.7, and the latest DLPC3478 firmware version is 8.0.1. 

    Please let us know if this can resolve your issue after re-flashing the EVM by following the steps above.

    Regards,

    Lori

    There is no projected image when the power supply and switch are both ON. I have the latest GUI version but I am unable to update the firmware of the DLPC3478. Also, the controller shows DLPC3430, not DLPC3478. When attempting to update firmware I get an error stating it is unable to find the location on my computer for the update.

    Hello Michael,

    Where does the controller show DLPC3430? Is this the marking on the controller itself? If so, please attach a photo of the EVM.

    What is the activity of the status LED's on the EVM? Do these change as the board is powered?

    Regards,

    The controller does not have DLPC3430 written on it. It is what is shown in the GUI when powered. Refer to the image I have posted in the original post for that. I also have attached to this a picture of the EVM. The LEDs on the EVM do change as the board is connected to power and when the power switch is changed to the ON position.

    Hi Michael,

    Can you please answer following questions to help us better understand your issue?

    1. Where did you get this EVM from? Is this a custom board?

    2. In the picture, I may don't see an optical module with RGB LEDs and DMD flex cable connected with the display board. Is that correct? What's your application use case?

    3. Can you please describe which LEDs are ON when you plugged in the power supply and which LEDs are ON or OFF after you moving the switch to the ON position?

    4. If you see the controller shown as DLPC3430 in the GUI, I think it maybe the default information when you don't have proper communication between the EVM and the GUI via I2C. Do you also see the EVM software and firmware version as 0.0.0?

    Regards,

    Lori

    1. I received this board from a customer, but according to them it is not a custom board.

    2. I have a custom projector with DMD flex cable attached so no use for the optical module. I just took this picture with nothing attached.

    3. I will have a picture of the board turned on below so you can see the LEDs turned on

    4. Yes the EVM software does show the firmware version 0.0.0.

    My client sent us a new board, the issue turned out to be a missing component on the shield and a short circuit somewhere on the board. I am very sorry for wasting everyone's time but I cannot thank you enough for at least entertaining my issue.
