Dear "Moffett, Kyle D",
In message 510974E8-A0C8-4E81-A034-B52F2AED12D0@boeing.com you wrote:
so why can't you have your do_reset() board hook negotiate with the other CPU to reset the system ?
That's what I originally implemented. The problem is the negotiation can take an unbounded amount of time to execute, so if it's run from the command line then it needs to be interruptible (EG: with Ctrl-C), which means it needs to be able to return an error.
Why would it need to be interruptable? When you type "reset", then you are gone. You cannot interrupt that command any more.
If it takes a long time like in your case, so you might print a message "Please stand by / have a cup of coffee while resetting" or so...
Best regards,
Wolfgang Denk
