I am getting errors in my gdb session connected to oocd as follows. Why is this happening ?

It looks like its a bug with gdb for sections that start at zero, as this post describes.

I am going to post this to the gnu-arm mailing list and see what they have to say.

OK, I fixed the problem.

For those of you that might run into this, here is what I did.

I found this post that explained the problem was gdb throwing out a section that it thought might be bogus.

http://sourceware.org/ml/gdb/2006-06/msg00123.html

Like the author of that post, I commented out the line

if (low == 0 && (bfd_get_file_flags (obfd) & HAS_RELOC) == 0) > return 0;

in file ./gdb/dwarf2read.c (from the Insight directory that I used to build arm-elf-gdb from.

I then did a make clean followed by a make all and make install.

I then ran arm-elf-gdb exactly as before and it works.
