Thank's for you help. I'm new on ipipe & xenomai. Yesterday= I find a problem related to my patch and the at91 clock initialization ( I= forgot to patch timex.h file ) and I will test serial line again as
so= on as possible. Now I try to integrate the leatest patch of ipipe from the = git repository.
I think that is not possible to have a "wired interrupt"= for the root domain, or exclude ipipe
for a series of interrupt (just = to try). I try to use linux without ipipe patch and I don't have
overrun= on serial line. It is possible to count unhandled interrupt? Maybe I have = some problem
but dosen't related to ipipe ( just visible with it ). are = there test suite for ipipe?
