Hi,
I am not using the ADI toolchain. I am using the toolchain provided by rtems.
*I compile my source using** bfin-rtems4.11-gcc. Then i load it
to bfin-rtems4.11-gdb and** connect it to the bfin simulator.
**Then i try to put a breakpoint in the file by opening then file.
**The debugger complains that there is no such line number. Also
**there is no optimization set while compiling. I also compile with
the -g flag so that the debug symbols are included.** This is making
my debugging difficult since i have to look at the** disassembly
for debugging. Is there any way i can use the C** source for debugging.*
I find only the RTEMS Tool Test Results
<http://www.rtems.org/pipermail/rtems-tooltestresults/> mailing group
on rtems. To which
group should i move this thread to.

Sorry I lost the mailing thread so i had to copy the mail contents.

Unfortunately, we probably need to move this to either the
binutils or gdb mailing lists. I am not sure which. Probably
the gdb mailing list is more likely to produce an answer.
Just to make sure I understand the bfin-elf gdb configuration
includes support for a debug connection to a target that
bfin-rtems does not? That doesn't seem correct given
that bfin-*-* is the pattern which matches both rtems
and elf bfin targets in gdb/configure.tgt
And the gdb's are built from the same source tree?
Why do you need the bfin-elf toolchain at all?
