You just need to find a place where you can save some information so it survives a CPU reset. Typically some registers or some on-chip memory or external, battery-buffert SRAM have this property. > One other thing that could help me is watchdog. > I saw on the email list that watchdog is supported, but the manual does not > list it (or I really need new glasses). Is this a board specific feature? Board and/or CPU specific. Some processors have a builtin watchdog, some boards use an external hardware watchdog chip. > Any further info or pointer to info is greatly appreciated. Hope this helps.
