CPU1 watchdog functionality on ZEDBOARD (XC 7Z020)

1_jiten

Hello All,

I want to understand how CPU1 watchdog works like how to enable, disable and set it. I have a zedboard and I have already installed Xilinx software development kit and Xilinx platform studio.

I have successfully run XAP1078 application so i want to add this CPU1 watchdog functionality in that app only or if there is any other separate code that will also works, so can you please share some example code

    also would like to add some points on the previous thread.

    I identified the addresses of watchdog load, counter, control, disable register but now what's happening when I set value on WD load register and enable the WD then my counter register start decrementing from counter register to zero and once it reaches to zero it reset the system and also reset the WD control, load registers value. now what i want is i don't want this reset so what i did  before load register reaching to zero I disabled the WD mode and enabled the WD timer mode even after that my system is taking reset.

    so any suggestions like how can I stop this WD reset.
