TMS320F28377S: HEX文件第一行不对，是哪里出了问题

您好，您的HEX文件是怎么生成的？

方便具体指明一下异常的情况吗？

通过生成的out文件，用hex2000

生成的，hex文件开始应该是:02000004003FBB，而这个hex有问题，第一行不是这种，直接是数据的hex，cmd没有问题

就是hex文件里的代码，cla里面的代码hex数据出现在我的flash之前，且第一行没有出现拓展地址

能再进一步阐明一下吗？方便我与相关工程师沟通

就是您说的02000004003FBB吧？

这是我的cmd配置，怎么把ramls0和ramls1的代码放到flash扇区

这个问题和您之前的问题有关联吗？

CLA的代码放置在FLASH中，运行时先copy到RAM中，再从RAM中运行。您帖出来的CMD文件就是这样的，CLA的代码存放在FLASHD，运行时copy到RAMLS0和RAMLS1中。

但是我的hex文件里，ramls0和ramls1相关代码还体现在ram区

您所说的体现是什么意思？

因为这些代码最终是要搬到RAM中运行，所以在TI的例程中，loadstart选择的是FLASH，而runstart选择的则是RAM

 您好，就是现在flash写入，C D扇区都能写入，但是flashE写不进去，知道可能是哪里的原因吗

您所说的不能写入是不能链接到输出文件中，还是可以链接到输出文件、但是无法烧入MCU的相关FLASH中？

可以链接到输出文件，无法烧入MCU的flash，flashC和FLASHd能正常烧入，但是flashe无法烧入，打断点编程语句也执行了，但是还是FFFF

打断点可以执行的话看一下反汇编，反汇编会显示代码存放的地址

反汇编怎么查看

debug界面下view-->disassembly，反汇编代码前面就会显示相应的地址
