W wiadomości od Nils Juergens było: > There may be a problem with the DMA transfer, maybe your IRQ and/or DMA Yes, there was a problem. *great shame of me* > comedi_config, and the dmesg output of one test run. dmesg output was alright and that belied me. (do not believe machines ever!) Longer story: I had not checked an IRQ used by module. So I have beed trying: 2: wrong!-I got an error (IRQ2 had beed used already of course), 3-everything was ok, driver was configured and dmesg output looked nice, insn was working, cmd - did not. I was sure (naive) that comedi is so clever that it can check (in some auto-magic way) if it was proper IRQ which should be used by hardware given by comedi_config options. There was no error at all, except that (basics forgotten) hardware and software were trying to talk with different IRQ! Maybe for such dumbos like me (I hope I am not only one;) there should be some info in documentation that even if everything looks good it may simply not work. But I am happy it turned out fine - I had learned few things about comedi internals (great stuff) and now I am sure it will work well in my system. Thanks for help. You showed me a right way.
