OK, I have taken the skel.c driver, and used chunks of the cb_pcidas code for attach and detach since the PCI interface is not dissimilar.
It appears to initialise the driver correctly, at least the io memory regions it allocates
are the same as /proc/pci reports are available.
However, when I call "comedi_config -r /dev/comedi1", the devpriv structure that should hold the addresses is full of zeros, but the device number is correct at 1. The detach routine then doesn't free the memory, and I have to reboot to try again.
Any ideas?
Richard
