--- Quote from: ywi on May 11, 2012, 04:08:20 pm ----> Thx, I did not catch that update. I can now configure my own debugger, but I get the following error message when I run it: "Starting the debuggee failed: Don't know how to run." I do not have this message with 10.05 ("do *not* run the debugee" option is disabled in both cases). When I use a custom command file (-x option) I don't get the previous error, I can talk to the proxy, erase and load the flash, but gdb does not seem to release the target from reset, so I cannot debug.

Steps to reproduce please, because I don't understand much of what you've written.
Keep in mind that I'm not embedded developer and proxy/reset/erase-load doesn't mean much to me.
ywi:
Case 1 :
=====
I configure the following :
Settings -> Debugger -> GDB Debugger -> MSPGDB -> execute path : /usr/local/bin/msp430-gdb
Settings -> Debugger -> GDB Debugger -> MSPGDB -> arguments :
I run the debugger :
...
Starting debugger: /usr/local/bin/msp430-gdb -nx -fullname -quiet -args /projects/cb/test/bin/Debug/test
done
Registered new type: wxString
Registered new type: STL String
Registered new type: STL Vector
Setting breakpoints
Debugger name and version: GNU gdb (GDB) 7.2
Starting the debuggee failed: Don't know how to run. Try "help target".
Debugger finished with status 0
Case 2
=====
a) I configure the following :
Settings -> Debugger -> GDB Debugger -> MSPGDB -> execute path : /usr/local/bin/msp430-gdb
Settings -> Debugger -> GDB Debugger -> MSPGDB -> arguments : -x /usr/local/msp430/gdb.ini
b) gdb.ini contains commands for the mspdebug proxy :
target remote :2000 // connect to the proxy
erase // erase flash
load // load executable to flash
continue // release CPU from reset
c) I run the proxy, then I run the debugger:
The debugger connects successfully to the proxy, the commands are passed to the proxy and executed successfully. But then I lose control on gdb (I can push the buttons, write commands in the command line, but they are not taken into account).
"do *not* run the debugee". It is disabled in both cases.
oBFusCATed:
Have you tried to setup the remote debugging options for your project in Project -> Properties -> Debugger-> Remote connection?
p.s. All please enable the full log in the Settings->Debugger, before posting more logs from the debugger...
ywi:
I set the remote connection in Project -> Properties -> Debugger-> Remote connection. It works. I not have the "Don't know how to run" error anymore (Case 1, default setting and not using a command file). I can see the gdb connect to the proxy and send the "continue" command. I then lose control over the command line and the buttons. I can stop gdb only by killing the proxy.
Here is the full log :

EDIT:
Please use code-tags if you post such an amount of log entries or source-code the next time, because it's much more readable.
I changed your post.
