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
