How do the files take affect?

There are flash and narmcore subdirectory in src directory. I want to modify the files in the two directory. But I haven’t find any makefile which including them. How do the files take affect?? Thanks. My environment is: NS7520 dev kit. GNU NET+OS 5.1

Those are part of na1b.bld. Once you build those they get built part of na1.lib.

But My enviromnet is GNU,What can I do ? I know *.bld is for Multi.Thanks
