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
