Is the Watchdog Timer Available to use?

Questions and discussions related to Inforce 6601 Micro SOM

Hi. It looks like there is a watchdog timer available to use and it is enabled by default (gpio_101 is wdog_disable, which is 0). How do I use the watchdog timer? Is there a driver for it?
thanks,
Kim

Hi Kim,

Yes the software and hardware watchdog are already enabled by default. Its primarily used when there is a crash to reboot the board into download mode for further debugging.

What do you intend to do with the watchdog timer?

Hi Ashwin,

I was wondering if I could use it to catch when the system is not booting properly. I have seen what this post shows: viewtopic.php?f=19&t=1001
so sometimes the boot process does not finish and then I have to cycle power to try again. It would be nice to use the watchdog timer to catch this case and then reboot. Is it possible?

Thanks,
Kim

Hi. I have not heard from you (Inforce) in a while on this. So I posted another thread to the 96board forum, describing my issue: https://discuss.96boards.org/t/how-to-a ... es/6329/12
They mention that the default behavior is for the qualcomm chip is "fused" to go into this reset mode when a boot failure happens. Since you are the vendor, is there anyway that you can change this default
behavior?

Thanks,
Kim
