Ubuntu 14.04 Xenomai Install

[benjamin_blumer]

Hi there,

I'm trying to install the drivers on Ubuntu 14.04 with a Xenomai 2.6.4 patched 3.14.17 kernel. I'm using the two-channel PCI card.

It seems to build fine:

Code: Select all

$ make clean
rm -f src/*o src/*~ src/.*cmd *o *ko *~ .*cmd  pcan.mod.c
$ make RT=XENOMAI
***

*** Path to kernel sources=/lib/modules/3.14.17-ap15.1215/build
*** use KBUILD=yes

--xeno-cflags is deprecated, use --skin=name --cflags instead

I think the make install is working fine too:

Code: Select all

$ sudo make install
Info: /lib/modules/3.14.17-ap17.1530/misc exists.
Info: Left current 'pcan'-entry in /etc/modprobe.d/pcan.conf untouched.
Info: Copied 45-pcan.rules to /etc/udev/rules.d.
Info: mainline drivers removed and blacklisted in
      /etc/modprobe.d/blacklist-peak.conf

But I can't modprobe the driver:

Code: Select all

$ sudo modprobe pcan
modprobe: ERROR: ../libkmod/libkmod-module.c:809 kmod_module_insert_module() could not find module by name='pcan'
modprobe: ERROR: could not insert 'pcan': Function not implemented
modprobe: ERROR: ../libkmod/libkmod-module.c:959 command_do() Error running install command for pcan
modprobe: ERROR: could not insert 'pcan': Operation not permitted

Any ideas?

Thanks

Hi,

Could you first try something for us:

Code: Select all

$ cd /home/benblumer/Desktop/peak-linux-driver-7.14/driver
$ sudo insmod pcan.ko

and tell us what happened.

Thanks,

Stéphane
