thanks for reporting. in the future, please use plain/text rather than HTML I will investigate (will need to get my hands on the hardware documentation to make sure it is ok to program the watchdog without getting/clearing the status flag) > > Expected Behavior: > * The bootstatus file should display flags indicating a watchdog > reset Your mileage may vary from one device/driver to another. Not all watchdog implementations may provide that information reliably (in other words, while we may be able to fix this issue for BX-21A, other devices may not support this bootstatus file) > > Thank you for your assistance. > > Best regards, > > Fatih Alperen Erdoğan > -- Cedric Hombourger Siemens AG www.siemens.com -- You received this message because you are subscribed to the Google Groups "EFI Boot Guard" group.
