Processor Expert generated code changes during debug session

marcos1 — Tue, 06 Oct 2015 13:46:28 GMT

I started a Processor Expert project but I'm having some difficulties with it.

When I generate the code and look at the sources everything seems to be generated as it is set up in the GUI.

When I build the project it still is.

When I start a debug session though I noticed the files get overwritten.

Namely (on a MC56F84789) I:

- changed the QSCI2 clock rate to the system clock

- added User code after PE initialization (in the build options tab)

Both are generated in the code and are still there after building the project.

When starting a debug session, though

- QSCI2 clock rate is being set to 2x the system clock

- my initialization code is being removed

The GUI still shows my settings though.

I only happened to notice this, because the file was still open in my editor and it informed me that the file has been changed.

Have you disabled code generation while build and the 'build before debug' setting?

See

I hope this helps,

No, both are enabled.

I would disable them, if only for speeding up things.

Let me know if this solves your problem.

I was able to figure out what went wrong.

When creating a debug configuration I accidentally selected the LDM version instead of the SDM version.

If I do this, the code is being changed reproducibly when starting a debug session.

If I use the SDM version everything works as expected and I can leave the 'build before debug' settings in their default state.

I don't really know what is behind the SDM and LDM concept, but this is the reason my project got messed up.
