Subject: [Xenomai-help] Analogy: unable to use sampling frequency higher that 10kHz

Message-ID: <4C0395C1.6050902@domain.hid> (raw)
Hello. I finally went back to work to my data acquisition
infrastructure. I'm now trying to increase the sampling frequency of my
control loop. I do not have any problem up to 10 kHz, but when I
increase the sampling frequency above this limits the ADC driver stop
working fine. In the kernel log I obtain a huge list of
Analogy: analogy_ni_pcmio: ni_mio_common: interrupt: didn't clear
interrup? status=0x9030
>From where can I start to investigate this problem?
I encounter this problem only when I use analogy commands with the
TRIG_WAKE_EOS flag. If I do not specify this flag all works fine up to
100 kHz. However I need my data in real time, and therefore I need to
specify this flag.
Cheers,
