watchdog

[Altera_Forum]

Hello everybody, 

 ¿Anyone has included a watchdog in sopc builder?  ¿Can I restart the watchdog from the c file loading in the micro?  ¿Is there any example with the watchdog timer?  Many thanks,  ifdm

You can add an interval timer configured as a watchdog. See the documentation here: http://www.altera.com/literature/hb/nios2/n2cpu_nii51008.pdf. 

To use it in your software, you first have to start it, and then regularly write any value as its period to reset it.
