I know that. Unfortunately, you took my above answer out of context. I replied to: > What about something like option 3: After the first error occurred that > may mark the beginning of a flood, disable that error interrupt until > the next stop/start cycle or the user has read the event? I was referring to *one* bus error. If one bus error occurs how will the driver know it is the beginning of a flood due to an unplugged cable? It can only tell after serveral consecutive ones. -- Sebastian _______________________________________________ Xenomai-help mailing list [email protected] https://mail.gna.org/listinfo/xenomai-help
