Hi.

I built Cross-compile(and debugging)
environment.(Host=linux32(ubuntu14.04) target=raspbian(Rpi2))

Cross-compile works well but cross-debugging doesn't.

I set debugging option as image.

And i set my target GDBserver as : root@raspberrypi:~# gdbserver
--remote-debug --multi 192.168.0.8:2345

And then, i request Debugging (press F9) in IDE,

I got result on target :

Listening on port 2345

Remote debugging from host 192.168.0.8

Remote side has terminated connection.  GDBserver will reopen the
connection.

Listening on port 2345

should i change option for "remote debugging" anything else?

It seems that you are running Windows version of CodeTyphoon. Use
native version of CodeTyphoon in your host.

THe options in the screenshot look fine.

What. if any, are the errors on the linux box?
Does the IDE show any error?

What is in "debug output", and can you supply a log file (see link)?
http://wiki.lazarus.freepascal.org/GDB_Debugger_Tips#Log_info_for_debu
g_session

What version of gdb is on the host, what version of gdb server is on
the raspi?

What are the debug settings on your project? Stab/Dwarf,  external dbg
info?

Also see http://wiki.lazarus.freepascal.org/Debugger_Setup

Code: [Select]And i set my target GDBserver as : root@raspberrypi:~#
gdbserver --remote-debug --multi 192.168.0.8:2345
Try

gdbserver 192.168.0.8:2345 ./Myapp

It should say that the process was created.

You must specify the app on the remote, as the IDE does not know where
it is located.

If possible still tell me the gdb(server) versions
