大家好,我使用了CodeWarriorV8.8 无操作系统来编译MPC8280的应用程序,发现编译出的文件在浮点数计算时有错误,排查后发现MPC8280的硬件浮点单元没有正常工作。请问在裸机情况下,Codewarroir上还需要进行什么配置或者程序还需要加入什么,才能使MPC8280的硬件浮点单元正常工作?

Please describe the problem in more technical details - i.e. which exactly floating point instruction you are using, for which data and what is the result.

Also please note this online technical support is worldwide, and our language is English only.


Have a great day,
