Hi Hans!

I’ve not been following this too closely, so forgive me if the question is a bit naive.

Since the sysupgrade process involves replacing procd now, would the watchdog need to be stopped as procd exits so that the hardware doesn’t reset itself during a particularly length update?  Let’s say you have a large FLASH with slow write times… that could take a long time and I don’t want a hardware watchdog thinking that the system has hung…

Thanks,
