I learned C2000 microcontrollers from my teacher Dan Block at University of Illinois Urbana-Champaign. If you would like to learn it, please check this website and his YouTube channel. To learn C2000 deeper, such as SYS/BIOS, you can check EmbeddedAdvantage. Of course, nothing is more useful than the official TI datasheets, technical reference manuals, etc.
