    Hello Lakshmi,

    EXT CSD register needs to be changed to reflect the emmc partition 1. I believe this is not supported by default.
    Once you reach U-Boot you could easily do that.

    Hello Keerthy,

    Thanks for the reply.

    I am looking for option to flash images to emmc boot area1 using uniflash.

    Currently using below option to program one image to emmc.

    call C:\ti\uniflash_8.0.0\dslite.bat --mode processors -c %COM_port% -f %PathImage%\firmware\u-boot.img -d 4 -o 0x280000

    But its programming to boot area 0. I could not find any argument to pass here to differentiate between boot area 0 and boot area 1.

    Is there any option to flash emmc boot area 1 via uniflash?

    Thanks,

    Best Regards,

    Lakshmi Shetty

    Hi Lakshmi,

    By default boot 0 partition is configured in the uniflash  programmer , you need to make changes in the source code and rebuild the  Uniflash Flash Programmer. to burn the images to the boot 1 area of emmc.

    Please configure the partition variable in function UFP_emmcInit as mentioned below.(<RTOS_SDK>/<pdj>/packages/ti/board/utils/uniflash/target src/emmc/emmc.c  )

    Once the changes are done rebuild the uniflash programmer as per the steps mentioned in the PDK documentation.
