本文详细介绍了在使用makefsfile程序生成文件时遇到的常见问题，即网页显示异常，原因是参数设置不当。通过正确配置makefsfile参数，特别是加入-h选项以嵌入HTTP头部信息，可以有效解决这一问题。同时，为了充分利用此功能，文章还指导如何在lwipopts.h文件中启用动态头部插入。此外，对于从SD卡或USB闪存盘提供文件的情况，动态头部插入也提供了便利性，允许直接从PC复制文件而无需额外处理。

使用TI makefsfile程序生成文件时，总是不能显示正常的网页。在网上查找到原因。

原来是makefsfile参数设置不对，应该使用以下形式：

makefsfile -i fs -o io_fsdata.h -r -h

Just to give you some background, without the "-h" option, makefsfile does not embed HTTP headers in front of each file. This can save quite a bit of space if you are using a large number of files but, to make use of this, you need to ensure that you build the web server with dynamic header insertion enabled. You do this by adding the line:

#define DYNAMIC_HTTP_HEADERS

to your lwipopts.h file (assuming you are using lwIP, of course).

Using dynamic headers is also helpful if you are serving files from an SDCard or USB stick since, you would typically want to copy files directly from your PC in this case rather than having to post-process them to add the headers.
