Problem using GDB and Eclipse with my stub

I'm making a new topic because I had a problem in the last
one (i've edited
my message but it hasn't been seen by mailing list users)

I'm working on the GDB startup management in my stub. The
log of the sent
commands is the following :

GDB -> (command sent by GDB through Eclipse)
Wrapper reply -> (reply from my stub to GDB)

Deleting socket.

And here is the log received in Eclipse (send by GDB I
think) :

0x40001258 in ?? ()
In Extended remote serial target in gdb-specific protocol,
#0  0x40001258 in ?? ()
target extended-remote localhost:3000
load
Invalid download offset: Eclipse/Blink/blink_ram_noflush.
info remote-process
Undefined info command: "remote-process".  Try
"help info".
mi_cmd_env_cd: Usage DIRECTORY
kill

1- The first line 0x40001258 in ?? () correspond to the
value of the PC sent
in the g command reply, but then I don't know what does GDB
makes. Can you
help me ?

2 - Moreover, at the end of this exchange, GDB closes the
TCP/IP socket ?
Why ?

Thanks a lot for your answers which will be very usefull to
me

I think you are misinterpreting the GDB commands and wrapper
replies. You won't get a $+# command, 
because + (on it's own is a positive acknowledgement. In
fact, the wrapper also has to send a + 
when it receives a command with a valid syntax and
checksum.

This is what it *should* look like:
GDB ->              $Hc-1#nn   (where nn is the
checksum)
  Wrapper ack ->  +
  Wrapper reply -> $#00 (Call unsupported or unrecognized
command method)
GDB ack ->         +

No.  Some of these are clearly sent by Eclipse (target,
load, info,
kill).  You need to figure out what your Eclipse is doing,
possibly by
debugging CDT.  GDB closed the connection because Eclipse
sent a kill
and probably closed GDB.

These two look kind of like your Eclipse and GDB do not work
with
spaces in pathnames.
