CCS3.3的一个工程,芯片是28335。只要设置Build option中启用了FPU,编译工程时就会报如下错误,怎么改配置都没有用,请问该怎么解决?
fatal error: file
"D:\\sunri_2\\DCDC_program\\201712\\App1025_1219\\App1025\\Project\\Debug\\A
C_Capacitor.obj" specifies ISA revision "C28FPU32", which is not compatible
with ISA revision "C2800" specified in a previous file or on the command

请参考这边帖子修改编译器环境配置:http://www.deyisupport.com/question_answer/microcontrollers/c2000/f/56/t/135465.aspx

感谢回答。报错的原因应该是工程的库文件和C文件之前是用没有FPU的编译器编译的,现在启用后编译就会有不兼容的问题;把 FPU support设成none或者softlib就没有报错误,可是浮点的运算时间就会很长了
