I have the code codesoucery versions.

I know nothing of that. Please tell me more.

I can get nothing in gdb to work with cortex.
spen> openocd contains a few hacks (define ARMV7_GDB_HACKS in armv7m.h)
that makes
spen> mainlinegdb behave better with the v7 arch.
Tell me more. Perhaps that is the magic that I am missing.
My tools must support multiple targets. If this means I build & install
two different OPENOCD executables I do not care. I just need to know.

spen> Could you give more details on your setup, as i have had no

I perhaps have a *TOTALLY* wrong 'openocd.cfg' file - I have tired so
many different ones that I am confused about which one worked when I got
it to flash the chip. Please if you can - send me one - complete -
standalone one that works with GDB ... or point me at one.
Otherwise - I use:
