TI中文支持网Part Number:TMS320F28335
请教个颠覆我认知的问题。
众所周知，hex文件中包含地址、校验等信息，而bin文件中只有单纯的数据，所以，理论上分析，同一个工程生成的hex文件应该比bin文件大很多，而我却遇到了hex文件比bin文件小的现象。
我用的是CCS6.1.1 ，对应的DSP芯片是F28335.cmd文件28335_RAM_lnk.cmd

1、HEX文件的生成方式是：在c2000 Hex Utility中勾选：Enable c2000 Utility
2、bin文件的生成方式是在post-build-steps写入指令："${CCS_INSTALL_ROOT}/utils/tiobj2bin/tiobj2bin" "${BuildArtifactFileName}" "${BuildArtifactFileBaseName}.bin" "${CG_TOOL_ROOT}/bin/ofd2000" "${CG_TOOL_ROOT}/bin/hex2000" "${CCS_INSTALL_ROOT}/utils/tiobj2bin/mkhex4bin"
最后生成的.out文件302kb，hex文件36kb，bin文件105kb
请教大神，这是什么情况？
Green Deng：
你好，看了你的生成方法应该都是OK的，那可能的原因就是工程本身或者CCS的问题。
可以用官方例程测试一下生成的hex文件和bin文件大小。如果官方例程测试没问题，那么可能就是CCS的问题了，可以更换CCS版本试一下：processors.wiki.ti.com/…/Download_CCS
