Debug GDB + gdbserver

Source: Internet
Author: User

GDB + gdbserver is a common method for debugging the target board.
After reading some online materials and some of my own experiences, write a complete record:
My environment is as follows: Host target:
NFS shared directory: Mount-T nfs-O nolock/home/itlanger/work/mnt

Compile arm-GDB:
Download the gdb source code:

$ CD downloads

$ Wget-T 0-W 30-C
Tar zxvf gdb-6.6.tar.gz
CD gdb-6.6
./Configure -- target = arm-Linux -- prefix =/usr/local/ARM-GDB-V

Sudo make install
Export Path = $ path:/usr/local/ARM-GDB
Compile arm-GDB-Server
Cd ~ /Downloads/gdb-6.6/GDB/gdbserver
./Configure -- target = arm-Linux -- Host = arm-Linux
Make cc =/usr/local/ARM/3.4.1/bin/ARM-Linux-GCC # Here is the path of the Cross Compiler
CP gdbserver ~ /Work ## gdbserver is compiled and generated
Export Path = $ path:/usr/local/ARM-GDB/bin (preferably added to. bashrc)

Copy the libthread Library (if this step is not done, an error will occur when running gdbserver !)
$ CD/usr/local/ARM/3.4.1/ARM-Linux/lib
$ LS-l libthread_db *
-Rwxr-XR-x 1 2619 man 29151
Lrwxrwxrwx 1 2619 man 17 2008-05-25>
Lrwxrwxrwx 1 2619 man 19 2008-05-25>

$ CP ~ /Work

Under minicom:
# Cd/lib/
# Cp/mnt/
# Ln-s
# Ln-s
Write a program, compile it with arm-Linux-gcc-G, and put it under the Work directory (My name is third)

Under minicom:


./Gdbserver 6666 third
Process third created; pid = 356
Listening on port 6666
Export Path = $ path:/usr/local/ARM-GDB/bin
Cd ~ /Work
Arm-Linux-GDB third
Gnu gdb 6.6

This GDB was configured as "-- Host = i686-pc-linux-gnu -- target = arm-Linux "...

(GDB) target remote 2345 ## (connection target)
Remotely debugging using 2345
0x40000dd0 in ?? () From/lib/
Now you can set breakpoints through L and B.
Run: run the command C #. Remember that run is not used here, because the program has been started by gdbserver on the target board. The output result is on the target board.

In this way, emacs can be used for remote debugging.
M-x gdba # (I have bound it to F10)

Run gdba (like this): Arm-Linux-GDB-annotate = 3 third
