Snap example fails.

[engink]

we are using X3_25M XMC module with PCI-E carrier card,
our kernel version is Linux 2.6.39.4 (Ubuntu).
i compiled windriver jungo kernel driver and kernel plugin
as described in "Linux notes" tutorial,but snap application fails
and giving error given below,

"Could not Open PCI Device. Error 0x2000000b: Kernel PlugIn failure"

I'm giving debug monitor output below,it can't find "KP_MALBU" module
so i changed MODULE_NAME as KP_MALBU but error still remain.

Using Ubuntu 11.04 32 bit and the stock 2.6.38-13 kernel, I have successfully installed and run our example program with no problem. It may be the case that you are having trouble because you are using kernel 2.6.39, but my intuition is that the problem is the change I had to make for Ubuntu.

Since our installs are built and tested normally under OpenSUSE and Redhat, one thing I had to change during the standard install of the driver was that when you run ./InnovDriver start, it complains that /etc/sysconfig/InnovDriverConfig is missing. The driver will not start without this command so for Ubuntu you have to Open the /usr/Innovative/InnovDriver file with a text editor and change the following line:

INNOVDRIVER_CONFIG=/etc/sysconfig/InnovDriverConfig

To this

INNOVDRIVER_CONFIG=/usr/Innovative/KerPlug/InnovDriverConfig

After I did this the driver started properly and all was well. Please note that you will have to run this command each time the computer starts. To automate this during the boot process you can add this to the /etc/rc.local file

/usr/Innovative/KerPlug/InnovDriver start

If you follow these instructions and there is still a problem, let me know and I can look further into this.
