我在尝试用FILELIB8的例程，但是编译有错，好像只支持IAR2.10 的版本，我用的是4.11的版本。然后我把库换成FILELIBF_V41文件夹里的CH375HFF.R43，源程序还是用FILELIB8的例程，编译一样出错。出错信息是： Warning[w6]: Type conflict for external/entry "mCmdParam", in module CH375MAI against external/entry in module main; class/struct/union Warning[w60]: The entry point label "__program_start" was not found in any input file. The image will not have an entry point. Warning[w35]: There is more than one definition for the struct/union type with tag '_CMD_PARAM'; class/struct/union field names do not Error[e46]: Undefined external "__program_start" referred in ?ABS_ENTRY_MOD ( ) Error while running Linker 这是什么问题? CH375HFF.R43是怎么加载的，我不太会? 我是这样加载的，不知道对不对：option-general option-library configuration-library-custom clib-然后就选择了CH375HFF.R43。我感觉不对？

库应该选用：FILELIBF_V41，库的添加方法与C文件一样

IRA编译器版本不能由高向低兼容，很麻烦,你可以使用CH376芯片,不需要加库,占用MCU资源更少.支持SD,U盘读写.是CH375的升级版.
