Hi,

I try to use sinus function on MCF5213 with Codewarrior. I am using the library C_4i_CF_MSL.a on my projet.

But when my software call the funtion sin this error occurs :

Error generate :

Access Error -- PC = 0X02DEEC

Error on operand write

Hi,

please check these points:

1. if math.h is included.

2. adjust ansi_prefix.CF.size.h as :

#define _MSL_FLOATING_POINT 1

//#define _MSL_NO_MATH_LIB 0

#undef _MSL_NO_MATH_LIB

#endif

#define _MSL_FLOATING_POINT_IO 1

3. add

#define __CF_USE_FULL_LIBS__ 1

to prefix text of Target setting -> C/C++Preprocessor

can this help you?

Have a great day,
Jennie Zhang

Thank you very much, you save me :smileyhappy:

Now I have an other problem... M_PI is not recognized.

Do you know how can I use pi (3.14...) ?
