GDB + gdbserver is a common method for debugging the target board.

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 192.168.0.33 target: 192.168.0.34
NFS shared directory: Mount-T nfs-O nolock/home/itlanger/work/mnt

1. Compile arm-GDB:

• Download the gdb source code:
• $ CD downloads
• $ Wget-T 0-W 30-C http://ftp.gnu.org/gnu/gdb/gdb-6.6.tar.gz
• Tar zxvf gdb-6.6.tar.gz
• CD gdb-6.6
• ./configure --target=arm-linux --prefix=/usr/local/arm-gdb -v
• Make
• 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 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 libthread_db-1.0.so
  Lrwxrwxrwx 1 2619 man 17 2008-05-25 libthread_db.so-> libthread_db.so.1
  Lrwxrwxrwx 1 2619 man 19 2008-05-25 libthread_db.so.1-> libthread_db-1.0.so

  $ CP libthread_db-1.0.so ~ /Work

  Under minicom:
  # Cd/lib/
  # Cp/mnt/libthread_db-1.0.so/lib/
  # Ln-s libthread_db-1.0.so libthread_db.so.1
  # Ln-s libthread_db-1.0.so libthread_db.so

Test

• The above environment variables are written ~ /. Profile
• Write a program, compile it with arm-Linux-gcc-G, and put it under the Work directory (My name is third)
• Under minicom:
• CD/mnt
• ./Gdbserver 192.168.0.33: 6666 third
  Process third created; pid = 356
  Listening on port 6666
• Terminal:
• export PATH=$PATH:/usr/local/arm-gdb/bin
• Cd ~ /Work
• Arm-Linux-GDB third
  Gnu gdb 6.6

• (GDB) target remote 192.168.0.34: 6666 ## (connection target)
  Remotely debugging using 192.168.0.34: 6666

• 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
• The effect is as follows:
