28335在CSS 3.3环境下编译的时候，突然跳出了这么一句警告，WARNING: invalid compiler option –float_support=fpu32
到网上找了个解决方式：
In addition to TI Code Composer Studio 3.3, there are four add-on packages that need to be installed in order for full Target Support Package TC2 support. They are：
- Service Release 8 (3.3.77) for Code Composer Studio
- TI C2000 Code Generation Tools v5.0.0
- Spectrum Digital Driver Release 3.03.23
- TI DSP/BIOS 5.32 (for RTDX support)
不知道这样能不能解决问题，四个文件也找不到。求指导！
