C6000串口加载程序

目前在做DSP6713的串口加载程序，基本流程已经没有问题了，但是通过PC机端软件把.HEX发送我DSP烧写FLASH未成功，梳理原因发现：

1  HEX文件只包含已初始化的块，但是我通过分析map文件发现很多在程序中初始化过的全局变量竟然分配到了.bss里，导致烧写程序不全；

2 请问第一条是我理解有误，还是CCS6.0配置问题？如下图...

0x2f568这个地址存放的是初始化的全局变量

    请问你看的是hex map文件？hex conversion utility不会转换.bss未初始化段。请看下面的文档hex conversion utility章节。

    Uninitialized sections are never converted, whether or not you specify them in a SECTIONS directive.
    Sections Generated by the C/C++ Compiler
    NOTE: The TMS320C6000 C/C++ compiler automatically generates these sections:
    • Initialized sections: .text, .const, .cinit, and .switch
    • Uninitialized sections: .bss, .stack, and .sysmem
