按照WIKI配置的系统，
eclipse, zylin 插件，GNU arm 插件
j-link/jtag, rt-thread 1.10
Sourcery_CodeBench_Lite_for_ARM_EABI 也是 WIKI 链接下载的
python 2.7 , scons
编译都正常
然后再 startup.c 里面的 main 设置断点
调试启动后很快自己停止了 GDB

下面是一些信息：
```JLINK GDB SERVER：
SEGGER J-Link GDB Server V4.40

JLinkARM.dll V4.40 (DLL compiled Dec  9 2011 18:59:34)

Listening on TCP/IP port 2331

J-Link found 2 JTAG devices, Total IRLen = 9

eclipse:
```target remote localhost:2331
0x00000000 in ?? ()
monitor flash device = STM32F103ZE
monitor flash download = 1
monitor flash breakpoints = 1
monitor clrbp
monitor endian little
monitor speed 5
monitor reset
monitor sleep 100
monitor speed auto
monitor writeu32 0xE000ED08 = 0x00000000
kill```

GDB 使用的初始化代码：
```# connect to the J-Link gdb server
    target remote localhost:2331
# Enable flash download and flash breakpoints.
# Flash download and flash breakpoints are features of
# the J-Link software which require separate licenses 
# from SEGGER.
# Select flash device
    monitor flash device = STM32F103ZE
# Enable FlashDL and FlashBPs
    monitor flash download = 1
    monitor flash breakpoints = 1
# Clear all pendig breakpoints
    monitor clrbp
# Set gdb server to little endian
    monitor endian little
# Set JTAG speed to 5 kHz
    monitor speed 5
# Reset the target
    monitor reset
    monitor sleep 100
# Set JTAG speed in khz
    monitor speed auto
# Vector table placed in Flash
    monitor writeu32 0xE000ED08 = 0x00000000

monitor reg r13 = (0x00000000)
monitor reg pc = (0x00000004)
break ResetHandler
break main
continue```

GDB 显示的信息是 arm-none-eabi-gdb terminate
有哥们知道原因么，谢谢。
