叶帆在他的文章《【.Net Micro Framework PortingKit - 04】修改启动代码&重写向量表》（http://blog.csdn.net/yefanqiu/archive/2010/01/03/5125745.aspx）已经很明确地给出了适合STM32F103ZE使用的启动代码和向量表的修改方式。但我认为有一点不足，就是这些修改都是在.NET Micro Framework Porting 4.1原有的框架之上的，如果在向STM32F103ZE移植的同时，还有别的Solution需要兼顾，则是一件非常痛苦的事情。所以，在这里采用另外一种方式来修改启动代码和向量表。

首先，根据这篇文件《重定位编译文件》（http://blog.csdn.net/norains/archive/2010/09/29/5913611.aspx）的方式，先建立一个位于./Solutions/[MySolution]/DeviceCode/cores/arm路径下的dotNetMF.proj文件。这一步非常重要，因为文章后面所做的更改，都是在这文件上动手。当然不要忘记，还要对NativeSample.proj进行修改，让它连接到我们这个新的文件。

1.打开已经重定位成功的dotNetMF.proj文件，做如下的修改：

原语句：
<ItemGroup Condition="'$(INSTRUCTION_SET)'=='thumb2'">
<Compile Include="$(SPOCLIENT)/DeviceCode/cores/arm/AssemblyCode/arm/$(AS_SUBDIR)/FirstEntry.s" />
<Compile Include="$(SPOCLIENT)/DeviceCode/cores/arm/AssemblyCode/thumb2/$(AS_SUBDIR)/VectorsTrampolines.s" />
<Compile Include="$(SPOCLIENT)/DeviceCode/cores/arm/AssemblyCode/thumb2/$(AS_SUBDIR)/IDelayLoop.s" />
<Compile Include="$(SPOCLIENT)/DeviceCode/cores/arm/AssemblyCode/thumb2/$(AS_SUBDIR)/Sampling_Profiler_RAM.s" />
<Compile Include="$(SPOCLIENT)/DeviceCode/cores/arm/AssemblyCode/thumb2/$(AS_SUBDIR)/VectorsHandlers.s" />
<Compile Include="$(SPOCLIENT)/DeviceCode/cores/arm/AssemblyCode/thumb2/$(AS_SUBDIR)/VectorsTrampolines.s" />
</ItemGroup>

更改为：

<ItemGroup Condition="'$(INSTRUCTION_SET)'=='thumb2'">
<Compile Include="$(SPOCLIENT)/DeviceCode/cores/arm/AssemblyCode/thumb2/$(AS_SUBDIR)/FirstEntry.s" />
<Compile Include="$(SPOCLIENT)/Solutions/STM32F103ZE_RedCow/DeviceCode/cores/arm/AssemblyCode/thumb2/$(AS_SUBDIR)/VectorsHandlers.s" />
<Compile Include="$(SPOCLIENT)/Solutions/STM32F103ZE_RedCow/DeviceCode/cores/arm/AssemblyCode/thumb2/$(AS_SUBDIR)/VectorsTrampolines.s" />
<Compile Include="$(SPOCLIENT)/Solutions/STM32F103ZE_RedCow/DeviceCode/cores/arm/AssemblyCode/thumb2/$(AS_SUBDIR)/VectorsHandlers_Func.c" />
</ItemGroup>

原语句：

<ItemGroup>
<HFiles Include="../../Initialization/MasterConfig.h" />
<Compile Include="Diagnostics/Aborts.cpp" />
<Compile Include="Diagnostics/FIQ_Profiler.cpp" />
<Compile Include="Diagnostics/RamTest.cpp" />
<Compile Include="Diagnostics/RamTest.h" />
<LIB_FIRSTENTRY_OBJ Include="$(OBJ_DIR)/FirstEntry.$(OBJ_EXT)" />
</ItemGroup>

修改为：

<ItemGroup>
<LIB_FIRSTENTRY_OBJ Include="$(OBJ_DIR)/FirstEntry.$(OBJ_EXT)" />
</ItemGroup>

2. 拷贝一个VectorsTrampolines.s文件到./Solutions/[MySolution]/DeviceCode/cores/arm/AssemblyCode/thumb2/RVD_S，输入如下内容：

3.拷贝一个VectorsHandlers.s文件到./Solutions/[MySolution]/DeviceCode/cores/arm/AssemblyCode/thumb2/RVD_S，输入如下内容：

5. 在命令行中进入到NativeSample工程目录，输入Msbuild /t:rebuild /p:flavor=debug;memory=ram 进行编译。如果没有错误，那么在调试时应该也不会出现问题了。
