I need to modify the source code of MDU project to add some more functions. But it seems that I cannot build it alone, it always complains about 'include/linux/version.h' not found.
I was able to build the entire firmware, but the make command will always cleanup and rebuild from scratch. It's kind of time consuming.
Is there a way to build just the project alone, or build the entire firmware incrementally?
Thanks a lot for your input!
