DLP2021LEQ1EVM: OK

Part Number: DLP2021LEQ1EVM

Tool/software:

Hello, I was wondering what it could mean if the racecar video just stopped working.

We have flashed the firmware several times, and have updated the offset accordingly. We followed the videos to the best of our ability but after flashing the board we only could get the projector to project a white screen, and when using the control program we were able to get static. Inside the composer, it appears that none of the python scripts will run, and we are unable to get the projector to respond in any way except for flashing and turning on and off from the control panel. Would you be able to offer some more guidance and assist us in getting this projector to work? 

  • Hello Ahmed,

    Can you please answer the following questions to help narrow down the issue you are facing? 

    1. Can you please provide your detailed step by step when you operating the EVM? 

    2. Are you able to display other images/video except white screen when you using DLP Control Program to send Video Start Address 1 -> Video Configuration 1 -> Video Control registers? You need to make sure you have the SPI interface connected. 

    3. Can you please send me your exported Composer project? I will try to use your project on our EVM to see if that works.

    Regards,

    Lori 

  • Hello Lori, 

    DLP2021_DGP_White.zip
    We go in the DLP composer we connect to the device switch it to Flash programming mode. Then we import the "25Hz white file" and open it up. Then we build the file in the composer. We get our build file we use the video offset data from the build log and after that we flash the entire programs output file. Then we open DLP control program copy paste the script from the pdf file and we try changing the videostartaddress1&2 and call on the offset data and it says in the variable list that its changed, but still all I can see is static we played around a lot in there with play, stop, changing different values, but nothing seems to work.

    Kindly,

  • Hello Ahmed,

    Thank you for the information!

    The attached zip folder does not include a exported Composer project in .dlpxproj format, so I couldn't import it to the Composer. However, I'm able to use your FlashImage.img file and program it to my EVM. After I switched the EVM to Host Mute mode and power up the EVM, I'm able to see a Warbler bird image displayed as default. Also, I'm able to change the display image by changing the offset address refer to the BuildLog.html file. 

    Here is the example for color bar:

    Please note that you are using White version of the project, so you should not see the actual colors. Can you confirm if you are using a RGB version DLP2021LEQ1EVM or a white version DLP2021LEWQ1EVM?

    I also noticed that you didn't include the racecar video in your build, so this could be the reason that you can not display the racecar video. 

    If you want to display the racecar video, then you need to checked the box in the Racecar video row on the Image/Video page of Composer and rebuild the project. After programming the new .img file on the EVM with FPGA Programming mode -> power off the EVM -> switch to Host Mute mode -> power up the EVM -> Using Control program to send above comments, but you need to change the Video Configuration 1/Frame Cnt to 0xDD for displaying the video. 

    Please try these steps on your EVM, and let me know if it can solve your issue.

    Regards,

    Lori
