Re: GDB startup session with Eclipse

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

Deleting socket.

1 - What is the real purpose of the '!' command (I'm french and I don't
understand weel the explanation in the GDB documentation).

2 - Is qSymbol mandatory ? What is a symbol and what are their use ?

3 - Why GDB sends me a 'k' command ? Yet, I'm assuming there is no running
software in my AT697 to kill. I just want to connect to GDB and make my
board enter in debug mode in order to load my application in my board using
GDB. Am I right ?

4 - Why GDB closes the TCP/IP socket at the end of this exchange ?

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