TMS320F28P550SJ: 使用TMS320F28P550SJ做RFFT计算时遇到问题

您好！

我在将F28P55x_rfft_fpu32历程迁移到自己的工程文件时编译出现如下所示问题：

例程中没有RFFT_f32_sincostabled的定义，fpu_rfft.h中定义了

Daniel：

您好

已经收到了您的案例，调查需要些时间，感谢您的耐心等待

您好，

hongwei liu 说：warning #10204-D: could not resolve index library "c28x_fpu_dsp_library.lib" to a compatible library

       应该是兼容问题。

       您工程中所有引用的库都是支持FPU的吗（floating-point libraries）？

我发现在F28P55x_rfft_fpu32例程中加入USB功能就会出现类似问题，如下：

请问F28P55x中RFFT和USB不能同时使用吗？我之前在28377S中同时使用过RFFT和USB没有问题。

Alice：

您好， 

    输出模式是COFF还是EABI?   工程中包含的驱动库和软件库需要统一格式。

    对于此芯片，C2000ware中提供的是EABI格式的驱动库。

    C2000 Migration from COFF to EABI

hongwei liu：

我使用的CCS20.1.0找不到output format了，如下：

请问如何知道output format 是COFF还是EABI？

我通过如下步骤建立工程：

1、导入C2000Ware_5_04_00_00\driverlib\f28p55x\examples里面的empty_sysconfig_128pdt.

2、拷贝自己的.c .h文件进入工程，拷贝自己编辑的sysconfig文件

3、设置include search path

,

hongwei liu：

c2000 compiler flags 中的–abi=eabi ，是否表示output format是EABI？
