Cannot debug C remote application - Solved [message #726673]

Hello,

I have troubles debugging a C applications:
My remote application is running on ARM7 linux powered embedded device.
I tried this:
1. build application in Debug mode on my Linux PC using arm toolchain
2. copied it into the embedded device
3. Launched gdbserver and application on the embedded device (./gdbserver :1234 myApplication)
4. Created a Debug configuration in Eclipse (C/C++ Attach to Application)
with specifying gdb for ARM, IP address and port (1234) number of the listening gdbserver
5. Launched the debugger (the gdbserver confirms connection on the embedded device) and got "No sources available for "Ox40003cbc" in the debug view.
6. When I push start/continue button, the application doesn't stop at break point (main) but exits.

The application just does printf("Hello World!!!\n");

Any idea how can I debug it?

Note: I am able to debug it using, for example, ddd frontend or just lauching
gdb
and then "target remote <ip address>:1234"
But no luck from Eclipse.

Thanks,
Ed

Here is a tutorial for remote debugging.

With the Remote plugin you can automatically upload your application, start gdbserver on the target and gdb locally.

Thank you for your quick reply.

I have dropbear on my target but not sftp.
I am able either to copy files using scp or by mounting directory on the target through nfs.

Is it possible to use scp instead of sftp?
Eclipse gives me error if it doesn't find the sftp.

Thanks,
Ed

Finally I managed to compile openssh for my target and get the sftp-server as stated in the link, and now it works just fine!

Thanks for your help

The latest release of the Target Management supports scp out of the box.
