Debugging issue
 
Hi all

Another newbe question :

Afdter I cross compile my C and LYNUX commands
into a cross platform , how do I debug this code ?

Do I use the regular LED and input switches debugging method like in the regular non OS boards ?

i know theree are emulators like Quem
but my code is hardware specific
and port specific .


So how debugging is done ?

If the target is running Linux, you can put gdbserver on it and debug from your build machine using GDB over serial or Ethernet: gdbserver

Thanks

What is exactly the "build machine" ?
Is it the target board under development ?

gdbserver is wonderful..

Many thanks

The build machine is the computer on which you cross compile programs.

The target is the board on which you run the cross compiled programs.

Actually, it can be quite painful to use. But it is better than nothing.
