MKL05Z32VLC4 (LQFP32) watchdog issue

[ssarathkumar916]

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,

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,
