Hi Robert,
This might be a little off topic, but it may help in your situation.
I just verified that the gdbserver/gdb combination in the Freescale
LTIB BSP tool for the M5208EVB function together (see logs at the
end). The LTIB tool is free so you can download it, take the gdb
pieces you need and use them in the uClinux environment or you could
look at the build log and see if that will help you build a working
combination.

Hi,
Well, talking with a buddy of mine, we've come to the conclusion that
the gdbserver in uClinux-dist-20070130.tar.bz2 needs a specific version
or versions of gdb, though I can't for the life of my figure out what
those versions might be. Doesn't somebody know what to do here?
We also figured a good strategy would be to attempt to build gdbserver
in userland. Searching around a bit, I found some recent postings (how
did I miss these? Oh, yeah, ARM, not ColdFire) here
http://www.mail-archive.com/[email protected]/msg00447.html that
suggests doing just that. I followed the suggestions made by Per
Hallsmark, but failed early in the process, as these errors can attest

Hasn't anyone used gdb/gdbserver that can help me?
Thanks!
