source level debugging for applications loaded dynamically into memory

Kishore Nanda

I have an application that is mapped to the DDR space during link time. During run-time the code is being copied to internal memory and executed from there. Since, the application was compiled with DDR memory-placement, the debug-information from the COFF file cannot be used to debug the application when it is executing from internal-memory. Debugging has to be done at assembly level...Is there a solution by which i can still debug at source-code level, while executing from internal-memory?

Kishore,

In the linker command file, do you have both a LOAD and RUN address specified for this section of code which is being loaded into one area of memory but run from another? Are you using memcpy or something similar to copy the code at runtime from load to run address? If so, source level debugging should be possible during execution as the linker is aware of the runtime location.

Agree that this is not a problem if it is a single application having a different load and run address. The problem arises when multiple applications are overlapped and run in the same memory region.

Kishore - are you doing what Aarti has asked? If so, you can probably do something like:

Note that while the topic discusses CCSv3, the same GEL script should work with v4.
