Error at program HALT : Can't find a source file at "src/knl/knl_run.c" and stepping does not work ...

Hi,

After having ported and compiled a previous CCS3.3 project now under CCS12, I have been testing the code and realising something is not quite right with the debugger set-up.

I can connect to the target using an XDS200 emulator, compile, link and load the xyz.out program. I can run it, but when I HALT the execution, I expected to have the last program execution code highlighted in the source code, underlining the last place the code was executing prior to the debugger HALT command - this was the behaviour of the CCS3.3 project etc. and pretty much all debuggers do this etc.

However I get no last execution line high-lighted, and the following window below is shown : 

I am not sure what source lookup path may this refer to, but certainly my code did not have a knl_run.c files, so it could not have been missing etc.

Also the project path is well known to CCS12 linker, including the DSP/BIOS, CGT v4.4.1 etc

I was hoping there is an explanation for this, somehow a missing path that should have been inlcuded etc. perhaps some suggestions please ??

Thanks and regards,

Mike
