    Hi vijendra,
    Refer section 3.3 of VisionSDK_Linux_UserGuide.pdf to have display over LCD
    3.3 Build Linux Vision SDK for LCD display (M4 Display)
    Note: Only TDA2xx and TDA2ex support 10.1” LG LCD.
     You must follow all the steps in software installation and build.
     Change the dtb picked in the uenv.txt from
    fdtfile=dra7-evm-infoadas.dtb  fdtfile= dra7-evm-infoadas-lcd-lg.dtb for tda2xx
    fdtfile=dra72-evm-infoadas.dtb  fdtfile=dra72-evm-infoadas-lcd-lg.dtb for tda2ex

    Hi,

    Have you changed the .dtb file for LCD.
    Please use dra7-evm-infoadas-lcd-lg.dtb file.
    Rename it in uenv.txt file placed in your boot partition .

    Regards,

    Hi Vijendra,
    If you are connecting any display device through HDMI, no need to change anything in uenv.txt file
    Default display device selected is display over HDMI

    Boot issue:
    Could you please check boot mode PINs are set to SD boot ?

    Regards
    Surya
