TDA3XEVM: Which Lepard Imaging camera do I connect to LI Camera connector for Parallel Video Input ?

Amer Naseem
Expert 1380 points
Part Number: TDA3XEVM
My usecase is:  UC_iss_capture_isp_simcop_display
I have Leopard imaging camera part number LI-CAM-OV10640-MIPI connected to CSI2 CAM LI Connector. 
From computer terminal, I select following ISS Usecase:
1CH ISS capture + ISS ISP + ISS LDC+VTNF + Display
With this selection, capture and display works fine.  I didn't make any code changes.
Does TI software support one of Parallel capture sources?  See attached.  If yes, will capture and display work without making any code changes?
Do I connect one of these parallel capture sources to LI Camera Interface?
Which Leopard Imaging camera can I connect to Parallel Video In Leopard Imaging Interface?  Is it connector labeled "LI Camera" ?
Do I need to change any board settings to select VIN1A or VIN2A ?
The user guide talks about CPLD.  What is the role of CPLD in parallel video?  Does parallel video go through CPLD to SOC ?
Regards,
Amer

    Hi Amer,

    Yes, there are two parallel input sensors supported for this usecase, AR0132 and AR0140 sensors on Aptina connector.
    On LI port, only Ov10640 sensor is supported.

    I accidentally clicked "Resolved".

    There are Two LI ports?
    1) CSI2 CAM LI port. I have OV10640 camera connected. This is serial port?
    2) LI CAMERA port. Is OV10640 camera supported. Is yes, can I connect same OV01460 camera that is connected to CSI2 CAM LI port. Or is there a parallel version of OV10640 camera? This is parallel port?


    Regards,

    Amer

    Amera,

    1, This is not serial port, this port is used for the CSI input
    2, this port is for parallel input, but with LI connector.

    Earlier, there were two sensors supported OV10640 parallel output and OV10640 CSI output. Parallel output is supposed to be connected to LI camera input and CSI output to CSL2 CAL LI port. But now only Ov10640 CSI output on CSI2 Cam LI port is supported. Please dont mix them as it can potentially damage sensor board and sensor.

    OK.  Does CSI stand for Camera Serial Interface?

    Are there Four differential raw video signals?  Red, Green, Blue?  What's the Fourth differential signal?

    We are making sensor board that will plug into 'LI CAMERA' parallel port. I understand that software isn't currently supported on this port.

    case '4':
    {
    Vps_printf(" This sensor NOT supported on current platform\n");
    }
    break;

    How much software work is there to support our sensor board for this usecase?

    Amer,

    It depends on which sensor you are planning to add. If it is one of the existing sensor, then you just need to remove this error condition check. If it is not, then you require to add the sensor in the sensor frame work.
