+
+This is a quick'n'dirty HowTo for cross-debugging on your iPAQ/Zaurus:
+
+Requirements:
+-------------
+
+1) You need the same binary of the program being debugged on the handheld
+   and on the desktop machine.
+   
+2) The binary for the handheld can be stripped (!!)
+
+3) The binary for the desktop must have been compiled with -g
+
+3) The same applies to shared libraries (but this is only needed if you want 
+   to step into libraries or if you want the backtrace to show the right
+   function names for libraries)
+      
+
+Setup:
+------
+
+1) install the gdbserver.ipk on the handheld.
+
+2) put the arm-linux-gdb binary somewhere in your $PATH (I would suggest
+   /opt/Embedix/tools/arm-linux/bin)
+   
+3) copy the sample.arm-gdbinit to your $HOME directory and rename it to
+   .arm-gdbinit
+   
+4) edit ~/.arm-gdbinit:
+   "solib-search-path" is the path, where gdb searches for shared libraries
+   "rtX" are some aliases to speed up debugging -- you can rename them, or
+   remove them (see below for the "target ... " syntax)
+   
+
+Sample session: debugging the launcher
+--------------------------------------
+
+1) Login on the handheld, kill Opie and execute:
+   
+   # gdbserver foo:2345 /opt/QtPalmtop/bin/qpe
+   
+   This starts the program qpe in debug mode, and the gdbserver stub now
+   listens on port 2345 for an incoming connection from the real gdb.
+   (foo should be name of the desktop machine, but it is ignored)
+   
+2) On the desktop, change to the $OPIEDIR containing the arm binaries
+
+   # cd $OPIEDIR
+   # cd core/launcher
+   
+   # arm-linux-gdb ../../bin/qpe 
+   or   
+   # ddd --debugger arm-linux-gdb ../../bin/qpe
+   
+3) You should get an "(arm-gdb)" prompt. Now do
+
+   (arm-gdb) target remote zaurus:2345
+   
+   You have to change zaurus to the hostname or ip-address of your handheld.
+   This should produce:
+   
+   Remote debugging using zaurus:2345
+   0x40002a80 in ?? ()
+   
+   (arm-gdb) break main
+   (arm-gdb) cont
+   
+   And gdb should stop in 'main'. If gdb complains about unknown symbol 
+   'main', you forgot to compile the application in debug mode.
+   
+   This is where the rtFOO macros come in handy: just type rtX and you are 
+   connected to machine BAR.
+   
+4) You can debug/step your application, as you would with a native gdb from
+   here on.
+   
+   Please note that single stepping in a cross-debugger can be VERY SLOW 
+   sometimes !!
