Re: [Xenomai-core] porting xenomai on imx25

[Roberto Bielli <roberto.bielli@domain.hid>]

Hi Gilles,

i try to give only another accurate information.

i made another test:
i write a xenomai driver for reading the timer and avic register and i 
see a strange behaviour.
when there is the problem the interrupt is NOT masqueraded in avic but 
the timer has the interrupt not acked.

After this i understand that now are my problems.
Do you know somebody that can help me understanding the problem only for 
xenomai side?
We can accept a quotation of work.

Thanks for all


information and if you
