Linux/TMS320DM8147: How to capture bt1120 data on DM8127?

Part Number: TMS320DM8147

Tool/software: Linux

Hi, all

My platform is DM8127, rdk is rdk3.8.0.

When I configure the sensor output bt1120 data to dm8127.

where i need to configure to tell the data is bt1120?

 

  • Hello,

    As far as I know, DM81x ISP doesn't support BT.1120 (though it supports BT656).  At least this is not covered in the TI TRM !

    Ideal place to configure such information  is ISP/ISIF. You can have a look at ISIF_CCDCFG.

    You may have to add a TVP5x decoder on to your device !

  • Hi,Ravikiran

    Thanks for your answer.

    We use soc sensor to output 16bit yuv data.

    I saw the datasheet: Parallel Connection for Raw (up to 16-Bit) and BT.656 or BT.1120 (8- and 16-Bit) .

    If i configure ISIF_REC656IF and ISIF_CCDCFG ,then it can capture the right image?

    Tim, Regards. 

  • Hello Tim,

    As per the Imaging subsystem guide BT656 is the only supported option. Also register manual suggests the same !
    But I checked the data sheet now and found it supports both !

    If there are some undisclosed informations, I am not aware ! But i will go with ISS documentation as it included all details on how to configure for different modes !
