The IPMC based hardware watchdog supervises board operation. There are 4 distinct
stages in the lifecycle of the system where different watchdog timers and actions are
used.
All watchdog parameters are stored in the bootloader environment. All times are in
seconds. All watchdog events will power cycle the board when the watchdog expires.
•
BIST watchdog during BIST
• OS loader watchdog during loading of kernel and INITRD
• Application Startup watchdog during startup of switching application
• Application Running watchdog during normal execution of switching application
