    Hi Kalaiventhan,

    Can you please check if you get any logs on the UART console on boot up? Can you please share the same with us? Display does not come up till the usecase is launched from the UART console.

    Also, is the image you are using in the SD Card the pre-built MLO and Appimage? If no, can you please try with the pre-build images?

    Thanks and Regards,

    Piyali

    ANS: we inserted pre-built images in the sd card,its not working.

    When you say UART is working.. do you see logs up to the Usecase Menu?? If yes.. you would need to start the usecase for the display to be up.

    To find if the SD card is bootable or not.. you can use open source linux tools like gparted to check if the boot and lba flags are set for the SD card FAT32 partition.

    Can you please refer to SBL User guide (ti_components/drivers/starterware/bootloader/sbl_userguide.pdf) section 5.4 MMCSD Boot Mode?
    It has steps to create bootable partition. There is 2 ways on windows to create partition, using Software tool or using DISKPART.

    From user guide -
    Make SD card partition as active using below tool:

    Additionally, Active bit can be checked and set in:

    kalaiventhan v ,
    If you follow the instructions from Prasad, you should end up with the partitioning similar to that in my previous post.
    You should be able to see MLO and u-boot files in the boot partition.

    Kalaiventhan,

    Please refer to Section 3.3 Uart settings of the VisionSDK_UserGuide_TDA2xx.pdf for how to get UART logs. On TDA2xx you would receive the logs on UART1. You would get logs like below on the UART terminal when the device is properly booted:
