    Hi Subhash,

    If you are running with RAM configuration please set the EMU_BOOT to EMU_BOOT_RAM and if running from Flash set the EMU_BOOT to EMU_BOOT_FLASH.

    If Watchdog triggers Xrsn your application doesnt know where to boot/start from again, if you set the appropriate boot mode you would see that the application runs over again and triggers XRSn in loop.

    Pro tip : Check the RESC register and you would see the WDRSn bit to check if Watchdog triggered reset or not

    Thanks.

    To select the EMU boot mode see below :
