Hello everyone,
I’m evaluating a x86 compatible controller card which has an integrated
Davicom 9102A network interface controller. The chip is hanging on the
PC104’s internal PCI bus. I was sent a (supposedly) QNX6 compatible driver
which I have now tried to get up and running. I haven’t got it yet, which
is the reason for this post. As the documentation for the controller isn’t
too long, I’ll just paste it in here…
How to startup the driver module automatically every time the system
starting up:
copy driver module(devn-dm9pci.so) to /lib/dll
and then add the following lines to the configuration file
/etc/system/enum/devices/net
DAVICOM DM9PCI
device(pci, ven=1282, dev=9102)
device(pci, ven=1282, dev=9009)
tag(devn)
append(legacy, “,nonet”)
requires($(IONET_CMD),)
uniq(netnum, devn, 0)
mount(-Tio-net “-opci=$(index)” /lib/dll/devn-dm9pci.so,
“/dev/io-net/en$(netnum)”)
That’s the extent of the documentation. Ouch!
I’m trying to generate a minimal build which I can use to boot from a
floppy, but with no success. The system boot normally, but when io-net is
called, I get the following message: “unable to load dll devn-dm9pci.so:
Library cannot be found”. I’m very inexperienced with QNX, so I really
don’t know where to start looking. I got other strange errors when I used
the entire shared library name for the -d option of io-net (the error showed
the name devn-devn-dm9pci.so, which is why I left off the devn. I couldn’t
find any QNX documentation explaining this either.)
I’ll tack on my build file to the end, to show what I’ve tried.
Any ideas, QNX gurus?
Thanks in advance,
Jason
