/* Define the memory block start/length for the F28335  
   PAGE 0 will be used to organize program sections
   PAGE 1 will be used to organize data sections

    Notes: 
          Memory blocks on F28335 are uniform (ie same
          physical memory) in both PAGE 0 and PAGE 1.  
          That is the same memory region should not be
          defined for both PAGE 0 and PAGE 1.
          Doing so will result in corruption of program 
          and/or data. 
          
          L0/L1/L2 and L3 memory blocks are mirrored - that is
          they can be accessed in high memory or low memory.
          For simplicity only one instance is used in this
          linker file. 
          
          Contiguous SARAM memory blocks can be combined 
          if required to create a larger memory block.

请看一下这个帖子：CCS/TMS320F2812: #10068-D no matching section warning

您好，这个帖子我不太看得懂他的解决办法，--gen_func_subsections这个选项我也不知道在哪里，能麻烦您教一下吗？

您好，这里我添加试过了，编译还是有警告，我觉得我BootLoader应用程序没执行的原因应该是程序入口地址固定的不对，我的CINT00段地址是 CINT00      : origin = 0x300000, length = 0x000050，但是编译生成的map文件中ENTRY POINT SYMBOL: "_c_int00"  address: 00303884，地址在FLSHH段，请问这是为什么？是因为我的#10068-D no matching section这个警告导致的吗？

好的。非常感谢分享~
