[yocto] Post Generation of debug information

[Oliver]

In this special case the tool is Lauterbach's Trace32. 

If I understand properly each piece of output I would eventually need, I would need to modify its origin recipes to ensure they deploy the such files in DEPLOY_DIR_IMAGE/SOME_WHERE. There I could proceed in a similar way as the image_types classes.
Paths are the first motivation, but physical addresses, offsets configurations which might could only be fetched from grepping the code could be next. Ideally I would not like to modify others recipes.
In a more generic way, is there a way a recipe accesses variables of other recipes?

There are ways implemented e.g. you can generate an image tarball in two pieces
1. binaries
2. Associated debug info and symbols

The untar both in same place.

Point your cross gdb to this location via setting appropriate sysroot
in .gdbinit
and that will be it.

However its not clear if thats what you are looking for. If you want to point to
components build directory instead of a full rootfs then you have to enhacne
the .gdbinit a bit more.

I am assuming that gdb is the debugging tool you are trying to use
