Hi all,
I am trying to use gdb 6.5 for target arm and on host Win/MinGW. I
have compiled such a version, and I do get undeterministic behavior
when using the debugger. I try to debug an elf file, which is to be
eabi compliant. It is not compiled with gcc, and has a gdb-stub built
in.
To rule out gdb problematics I have two questions:
1) Does GDB 6.5 support mixed ARM v5 and thumb instruction set binaries?
2) What is the right compilation config parameters in this case?
I have tried the --target=arm-thumb-elf and --target=arm-gdb-elf
Could anyone please help me out in this matter?
Best regards
/Johan

Yes.

The middle field doesn't matter. Either of those should work, though
you probably want --target=arm-eabi.

You haven't told us anything about what goes wrong, so there's no other
help we can offer yet.

We are using it and it does. However, it has issues with knowing if
the current pc is pointing at arm or thumb code and so can get
confused.
