Hi,
I assume they have built the executable on the same machine they want to debug it (no conflicts in path to the source files).
Please make sure to add GHS compiler flags to enable generation of debug information + flag to generate elf-dwarf2.x standard.
Could you post a screenshot if the suggestion above does not help?
Note:
Please check the link below for some more info about debugging GHS code under S32DS:

Hope it helps.
