I have installed GDB using apt-get. The host and targets are the same. I want to use it for cross debugging. Could anyone help out how to achieve this ?
Thanks in advance,

Thanks, but I have come across this article before and it assumes that the GDB is already configured with --target=arm-none-linux-gnu,Praveen– Praveen2015-10-12 11:06:07 +00:00Commented Oct 12, 2015 at 11:06

You can't.
You need to build (or install a prebuilt one -- it's often included with your cross-compiler) a cross-gdb, and use that to perform cross-debugging.

You should install gdb multiarch in ubuntu and gdbserver in the arm-linux target, that will allow you to remote debug programs in the arm target.
Example:
In the target:
target> gdbserver :2345 emacs foo.txt
In the ubuntu machine, start gdb and execute the command:
(gdb) target remote the-target:2345
See the manual for more details: Using the gdbserver program
