Hello everybody, 

 

this is my second question on watchdog of Kinetis MCUs. 

I have been working on this for a while now and I can't get my head around it. I am using a Cortex M4 K20 micro for my application. I have managed to configure the watchdog successfully and it is working fine. but if the watchdog is not kicked on time it does not seem to be executing its interrupt service routine before doing the reset. my watchdog configuration is 100% right, I have even tried the KSDK drivers to do the configuration. none of them seem to be executing the watchdog isr.

I did everything I could to find out whether this isr is executed or not. 

I did a lot of research online, some -people say, it is not possible to put break point inside the watchdog isr. 

does anybody have an example of kinetis watchdog with interrupt enabled which has been tested and works for sure.   

 

many thanks for any response,

Roosbeh
