use LMA instead of VMA?

[Torsten Mohr <tmohr@s.netic.de>]

Hi,

i'd like to test my startup code in crt0.S but have some
problems with that as gdb uses the sections VMA instead
of the LMA.

For this i can't test my code in the simulator, as .data
and so on are always overwritten with incorrect data.

At the moment i use the preprocessor and -DREAL_TARGET=0 or =1
to generate an ELF file for the target or for the simulator.

Is there a better way to work around gdbs behaviour here?

Would it work to use objcopy --change-section-vma .data= \
load_address(.data) to set a sections vma?

Or would that crash something else then?

What else would be the preferred way to test a startup code?


Best regards,
Torsten.
