MKL05Z32VLC4 (LQFP32) watchdog issue

Hi,

We are using MKL05Z32VLC4 (LQFP32) in our product. During the production one of our board got failed. While Debugging , we understood that its watchdog reset the micro controller faster than usual.

We are writing 0xc in the SIM_COPC register for initialisation. We are writing SIM_SRVCOP register at every one second interval.

Please help us to solve this issue.

Thanks,

Sarathkumar S

Hi,

We are using Rowley Cross works for Devopement and rowley cross connect for debugging. We can able to debug the controller without disabling the watchdog. We checked RCM_SRS0 register after reset. It was 0x20 (Reset caused by watchdog timeout).

Thanks,
