GDB debugging problem

[mschuckmann]

So I've followed the instructions in the Linux User Guild pdf to get gdb debugging working on my XPortPro 16mb device and I'm having a problem.

Here is what I've done:
I enabled GDBSERVER via menuconfig.
I'm booting my device via nfs root (but I don't think that matters)
On the device I run the command:
/ # gdbserver :2345 /bin/pwc

On the host systems I run gdb with the command:
$ m68k-uclinux-gdb nfs/bin/pwc
Followed by:
(gdb) target remote 10.15.0.55:2345
Remote debugging using 10.15.0.55:2345
0x408a0044 in _stext ()
(gdb) break main
Breakpoint 1 at 0x408a0156: file /home/dev/builds/wallnet/lantronix/build-xport/linux/user/lantronix/planar/wallnet/pwc/pwc.c, line 188.
(gdb) continue
Continuing.
Remote 'g' packet reply is too long: 4089ca140000000000000006408f7f38000000004089800440 8f06f6408f08d8408a0156408adec04089df344089ca004089 b7c840898004408adec44089dee000000000408a0158000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 0000000000
(gdb)

At this point GDB seems to think the app is running on the target but I don't think so.

I've googl'ed the message "packet reply is too long" message and most people indicate it that it's a missmatch in gdb and gdbserver's understanding of the target architecture but I have yet to understand what to do about it.

So I'm hoping that someone other there has some in sight on how to get this working.

Thanks,

Solved my own problem a mere minutes after posting here.
In menuconfig there are 2 GDBSERVER options that can be enabled
gdbserver & gdbserver (old)
I foolishly thought that I needed to enable the, presumably, newer but it turns out that I needed to enable the (old) one.
Things seem to work now. Although I am seeing GDB report the following 2 warnings:
warning: Target reported unsupported offsets: Text=409a0040;Data=409a68a4;Bss=409a68a4;

warning: RMT ERROR : failed to get remote thread list.

I don't know anything about the first and for the second I suspect I'll have trouble should I try to use threads.
