Original question:

TDA4VM: Some questions on TDA4 board and DCC

TDA4VM: DCC tool and EVM interfacing

Part Number: TDA4VM

Hi TI member,

So I am trying to utilize the single_cam demo from TI to use the DCC tool. I went over the demo mentioned in ISP Tuning Overview document. However, the DCC tool is on the windows computer whereas, the board's PSDK is setup in the linux machine. How do I interface the two to get the DCC tool working? Is there any documentation that can be proivded to mention the setup between the two?

Thanks

    Hi,

    The tuning tool does not need to access the linux machine for building PSDK.

    So while tuning, how do we run the app_single_cam demo? Currently I have the ethernet cable linked to my windows PC and the EVM connected to the linux via a serial cable to run the single_cam demo. Is this correct or should it be done differently?

    The tuning tool on PC works mostly on captured raw sensor images.

    The single cam app runs on EVM.

    While the app is running, you may save the raw images to SD card on EVM and then mount the SD card to your Linux and copy the images over to PC.

    If your EVM has network connection, the PC tool can capture images from EVM directly.

    Okay, so when I capture the RAW images and then open them on the DCC tool, the following are the steps I did:
    1. Run the single cam app on EVM, save images onto SD card, transfer them to my Windows PC. 
    2. Open the DCC tool, I get the above error. I have the .dll file in the DCC/bin/ directory.
    3. But if i do click ok in the dialog box, it takes me inside the tool after selecting VPAC v1 (since I'm using TDA4M).
    4.    This page comes up and I create a new project here. 
    5. Then I get presented with the box to choose RAW image specs. I am using a TDA4M board and IMX623ES2 cameras. So is this the correct specs to be entered?

    6. After that, I open the raw files in the browse section and click on any raw image that was captured. 

    Are these steps correct?

    Hi,

    You might have missed installing the required dependencies.
    Please take a look at the "Installation Dependencies" section in the release note and install all the dependencies.

    The image size is decided by your IMX623 sensor driver and you may check with your driver provider for details.
    It is very likely to be 1936x1552 for IMX623.

    Best,
    Gang

    Hi, yes changing the sensor dimensions worked for the image. However, I am still facing issues with the MATLAB initialization even after installing the mentioned dependencies.

    That is not expected.

    Could you please try to uninstall/reinstall the tool, reboot the PC, or try on another computer?

    So, turns out I had another MATLAB version installed and removing that and having just the runtime resolved the issue. Thank you for the support.
