Remove CCS from the list. This is a host side Integrated Development Environment (IDE) tool for managing your target (OMAP-L138) software project, compiling, etc.
I suspect you would utilize BIOS on the DSP side of the OMAP-L138 and perhaps Linux on the ARM side of the OMAP-L138. There should be information on the OMAP-L138 Product folder regarding software development kits to get you started.
