Hello There,
I'm configuring the Watchdog timer but I'm unable to achieve the interrupt even after the counter is reaching the maximum value.
Can you Please help.

    Hi Tejas,

    Have you had a chance to reference the watchdog example provided in C2000Ware? From your configuration files, it appears that you've mapped the ISR routine to a funciton named INT_WAKE_ISR(). However, you are showing a different ISR named MCAL_WATCHDOG_ISR() that has your ISR counter. 

    Which interrupt routine is targeted for the watchdog? Currently it is INT_WAKE_ISR(), this means that your code tied to the watchdog needs to defined in this function.

    Regards,
