DM388 watchdog out pin problem.

Other Parts Discussed in Thread: DM388

Hi,

We have develop DM388 base IPNC.

DM388 provides internal watchdog time.

I had enabled watchdog in kernel. Application is opening watchdog driver and send keep alive periodically.

If Application kills or hang watchdog resets CPU.

We also uses AJ30 pin (RSTOUT_WDT_OUT) pin to provide reset signal to all peripheral ics in case to reboot via watchdog.

At power on reset time RSTOUT_WDT_OUT pin is low and then become high after processor come out of reset. We had connected external pull up.(10K)

Problem: If watchdog timer reaches zero and processor reboots this RSTOUT_WDT_OUT pin is not provide any signal and remains high only.

Please provide solution on this.

Regards,

Kunjal
