Hi,
I'm assuming you're following this page:
http://rivendell.tryphon.org/wiki/Debian_6_GPIO_MC_PCIDIO24
Have you added two boards? I'm trying to figure out why you have gpio0
and a gpio1. You may find that by some strangeness gpio1 is your real
card and gpio0 is some odd error state.
You can always try gpitest and change the device to read /dev/gpio1 if
that helps at all.
Regards,
Wayne

I'm working with another engineer to get Rivendell systems alive to
replace several BSI Wavestation platforms and we have hit a snag.
We've install Debian 6 from scratch and have Rivendell 2.4.0 installed
with JACK audio and working. Now we need to add support for the
Measurement Computing IO boards.
We've installed and compiled GPIO 1.1.0 following the instructions in
the Wiki and have two GPIO devices (/dev/gpio0 and /dev/gpio1).
IWe've changed the permissions to rw for all users but when weI
run the gpitest and gpotest we get an "Unable to open GPIO device"
error.
There is an ioctl error in the syslog :
ioctl32(gpitest:3161): Unknown cmd fd(7) cmd(80044501){t:'E';sz:4}
arg(fffaa1ec) on /dev/gpio0
Any ideas??
Thanks
William
