Timer watchdog is not reset the nios.

Hi,

I want to add a watchdog with timer to my project.

I added to platform design the timer and the configuration i set is in pic1.

After I generated the HDL file, i added InitTimer_1(); function in C platform in pic 2.

In addition, every 10ms i am writing to period registers (pic3) as said in the user guide(pic4).

I did a while (1) loop in order to stuck the program. But there is no reset.

I know this because in the while loop i blink a LED on my board so the program still running and didnt restart?

Please advise.

thanks.

    Hi,

    I see you are connecting the reset_request signal to the same timer reset pin. It will keep resetting the timer itself. If you need for example to reset the NIOS you must connect it to the NIOS II reset pin or you can reset the main CLK if you want.

    Regards,
