Hi Everyone,
I am trying to connect GDB-7.5.50-1 to the target but I am getting an error
.In addition I gave the command
Furthemore the host and the build system are compeletly running but the only problem with target. I am using cygwin.
So if anyone has some suggestion then please post it...

gdbserver
gdbserver(1) GNU Development Tools gdbserver(1)NAME
gdbserver - Remote Server for the GNU Debugger
SYNOPSIS
gdbserver
tty prog [args...]
gdbserver tty --attach PID
DESCRIPTION
GDBSERVER is a program that allows you to run GDB on a different machine than the one which is running the program being debugged.
Usage (server (target) side):
First, you need to have a copy of the program you want to debug put onto the target system. The program can be stripped to save space if
needed, as GDBserver doesn't care about symbols. All symbol handling is taken care of by the GDB running on the host system.
To use the server, you log on to the target system, and run the `gdbserver' program. You must tell it (a) how to communicate with GDB, (b)
the name of your program, and (c) its arguments. The general syntax is:
target> gdbserver COMM PROGRAM [ARGS ...]
For example, using a serial port, you might say:
target> gdbserver /dev/com1 emacs foo.txt
This tells gdbserver to debug emacs with an argument of foo.txt, and to communicate with GDB via /dev/com1. Gdbserver now waits patiently
for the host GDB to communicate with it.
To use a TCP connection, you could say:
target> gdbserver host:2345 emacs foo.txt
This says pretty much the same thing as the last example, except that we are going to communicate with the host GDB via TCP. The
`host:2345' argument means that we are expecting to see a TCP connection from `host' to local TCP port 2345. (Currently, the `host' part
is ignored.) You can choose any number you want for the port number as long as it does not conflict with any existing TCP ports on the
target system. This same port number must be used in the host GDBs `target remote' command, which will be described shortly. Note that if
you chose a port number that conflicts with another service, gdbserver will print an error message and exit.
On some targets, gdbserver can also attach to running programs. This is accomplished via the --attach argument. The syntax is:
target> gdbserver COMM --attach PID
PID is the process ID of a currently running process. It isn't necessary to point gdbserver at a binary for the running process.
Usage (host side):
You need an unstripped copy of the target program on your host system, since GDB needs to examine it's symbol tables and such. Start up
GDB as you normally would, with the target program as the first argument. (You may need to use the --baud option if the serial line is
running at anything except 9600 baud.) Ie: `gdb TARGET-PROG', or `gdb --baud BAUD TARGET-PROG'. After that, the only new command you need
to know about is `target remote'. It's argument is either a device name (usually a serial device, like `/dev/ttyb'), or a HOST:PORT
descriptor. For example:
(gdb) target remote /dev/ttyb
communicates with the server via serial line /dev/ttyb, and:
(gdb) target remote the-target:2345
communicates via a TCP connection to port 2345 on host `the-target', where you previously started up gdbserver with the same port number.
Note that for TCP connections, you must start up gdbserver prior to using the `target remote' command, otherwise you may get an error that
looks something like `Connection refused'.
OPTIONS
You have to supply the name of the program to debug and the tty to communicate on; the remote GDB will do everything else. Any remaining
arguments will be passed to the program verbatim.
