I want to share with the community this tutorial I just finished for versioning our projects. The tutorial can be reached here:
It also works for MCUXpresso, and with any other platform based on Eclipse. There are two tricky issues to observe when versioning:
1.- ALL files in the workspace shoud be versioned, not only your .c* and .h* files (except binaries).
2.- The original .metadata hidden folder must be included.
These two points are handled in the tutorial.
Please let me know if it worked for you.
