BSP-Generation: Problem find custom device drivers from command line

If user_components.ipx works for both software and HDL, then the IP_IPX_PATH variable should also work.

If you look in the file:

$QUARTUS_ROOTDIR\sopc_builder\bin\root_components.ipx

At the end of that file, are the lines

  <!-- Additional comma-separated list of locations -->
  <path path="$IP_IPX_PATH" />

That folder also has the program ip-make-ipx.exe which will create a file called components.ipx for all the components it finds in the directories/subdirectories where you run it. This tool might also work for drivers, I've never tried.

You should be able to do something like

$ export IP_IPX_PATH=<comma separated paths to .ipx files>

$ make

(where the makefile calls any of the command-line Altera tools)

Cheers,

Dave
