CODECOMPOSER: How to add source files for manual debug

Tool/software:

Hi, 

I am creating the necessary files to flash the IWR1642BOOST mmWave sensor using another tool, and I am attempting to debug a few issues in CCS Studio. I utilized the manual debugging option. After selecting the appropriate target configuration, I loaded the program xyz.xer4f. A breakpoint was triggered in the main code; however, when encountering a function located elsewhere, the control does not proceed beyond that function, resulting in an error. Additionally, I am unable to step over the functions.

1. What could be cause of this ? 

2. How do I add source files in the case where there is no project? (Since I am just using .xer4f file to load symbol and manually located main file.) 

3. I understand there is load symbol option as well, can u guide us on how to use this?  I tried loading .map file, then I got an error :  Encountered a problem loading file: Could not determine target type of file

4. Do i have to manually reset the board everytime, I have to reset the debug. If i dont do reset on the board, the debugger goes to exit(). 

I am using CCS Studio 12.7.1 

Thanks in advance
