[Xenomai-help] Too much Interrupt

[Xenomai-help] Too much Interrupt

[Hubert Talbot]

Hi,

I work with Sensoray S626 IO card.

My test consists in generating signal with a calibrator, one per second during 5 seconds.

I use rt_intr_wait and I get about 50000 interrupts, I have to filter them to count only the good ones (5).

The provided demo does not behave this way. It receives only the ones generated by the calibrator. 

Where do the ~50000 interrupts come from?

Thanks

Hubert

A stupid advice: did you check rt_intr_wait return value ? Maybe
something is badly configured and rt_intr_wait returns an error 50000
times ?

I'm not sure whether my e-mail has been received or not, so I'm posting it
again. Sorry replications.


Hi all, I'm trying to embed the
linux-2.6.24 with xenomai-2.4.3 on powerpc processor. Although when I try
to execute
/scripts/prepare-kernel.sh on xenomai directory I unfortunately get the
message at the end :

......

Unable to patch kernel 2.6.24.4 with adeos-ipipe....

Have you seen this problem? Could you give me some tips?

Thanks,

Breno

Yes, this is the third time we receive your post. Please stop this.

[Xenomai-help] Rép. : Re: Too much Interrupt

[Hubert Talbot]

There is no more problem (sorry for omitting advice).

It was not related to Xenomai. The problem was with the I/O card. 

rt_intr_* calls were not sufficient. I had to make I/O card API calls too.

Something like this:

while (!end)
{
    rt_intr_wait();

    // disable interrupts
    rt_intr_disable();
    InterruptEnable(board, FALSE);    <-------------- this call was not there when the problem was

    processing...

    // reenable interrupts
    rt_intr_enable();
    InterruptEnable(board, TRUE);
} 


Thanks

Hubert
