(Linux)(Embeded system)(C)(C++)Remote debug by GDB server

設定環境

• Host (PC)(Ubuntu)

  • 安裝Cross-Compile GDB & GDB Server

    • 下載GDB Source (內含GDB & GDB Server)
      http://www.gnu.org/software/gdb/download/

  • Complier GDB

      cd <GDB source>
      ./configure
      make
    

  • Cross-compiler GDB Server

      cd <GDB Src>/gdbserver
      ./configure --host=mipsel-linux
      make
    

  • 安裝CGDB方便操作GDB

      sudo apt-get install cgdb
    

  • Cross-compile with GCC Debug option “-g”

• Target board

  • 將放在target board
  • 將放在target board

進行Remote debug

• Target board

  • GDB Server 設定Listen Port

      <cross-compiled gdbserver> localhost:<port> <cross-compiled  application>
    

• Host

  • 使用CGDB啟動GDB

      cgdb -d <cross-compiled gdb> <cross-compiled application>
    

  • 切換至GDB模式

    • CGDB與GDB模式互換

      • GDB->CGDB: 按下”esc”
      • CGDB->GDB: 按下”i”

    • GCC Debug command連上GDB Server

        target remote <target board IP>:<target board port>
      

  • GCC Debug command

    • list (l) –顯示程式
    • continue (c) – 離開中斷點，繼續執行程式
    • run (r) – 開始執行程式
    • next (n) – Step over
    • next (s) – Step in
