Problems with my own Drivers

If you use the Altera nios2-bsp script with the --debug option, you should see lots of output related to finding locating system ip modules and finding the best driver match.

1. Make sure the search path to your _sw.tcl file is present at the beginning of the debug output. If your IP is located in a standard location such as the quartus project folder, then you are ok.

2. Search for your discovered module in the debug output. You should see the attemp to match a driver to your module. You should see your driver and a reason as to why it was not considered compatible (skipped over)
