Hi, trying to tune up my Comedi-Rtai system, I still have a problem: kernel says to me "Can't locate module char-major-98-0". Is this a problem? Before including my DAQ board functionalities in a new Comedi style driver, I've tried to call Comedi commands (such as comedi_data_write) to see what passes from user to kernel space, i.e. from an executable to the driver. What I see is nothing! Suppose a call such as data = 0xaa; /* to have a significant pattern in dio channels: 010101...*/ comedi_data_write(it,subdev,chan,range,aref,data); I'm sure that this call refers to the dio instruction function (below the prototype) in my driver (some printk confirm it), but where should I find my data? Just to print out it.... static int s626_dio_insn_bits(comedi_device *dev,comedi_subdevice *s,comedi_insn *insn,lsampl_t *data) Does the problem mntioned above in some way stops data? Hope to be useful for you in future, now I'm still new and I need help. Thanks, Mic. -- PhD, Politecnico di Torino Dipartimento di Automatica ed Informatica
