[quote user="jan2809"]Do you know if I use an external compiler would I be able to do the debugging in CCS.[/quote]
It depends. If the output from the compiler for the file format and generated debug symbols are a standard format (like ELF/DWARF), then it is likely support by the debugger. If it proprietary format like output from IAR, then it is not. GCC output is well supported by the CCS debugger and later versions of CCS even ship with ARM and MSP GCC compilers (or available via update)
[quote user="jan2809"]As well I am not able to find the documentation describing CCS compilers and make. Any idea where it is?[/quote]
User's guides for TI compiler/assembler/linker can be found here:

CCS uses gmake under the hood to build CCS projects. For more details on how the CCS build environment works, see:
