Using AMCLIB / GFLIB into an ISR

Hello,

 

 i use MPC5777C with S32-studio.

 

I tried to multiply in an ISR. If i call for example the function MLIB_Mul(FRAC32(0.185), FRAC32(0.195), F32), an IVOR1-exception occurs.

Then i tried the function  MLIB_Abs() within this ISR. Its output result is the same as input (negative sign) - not ok.

 

In any loop, which is called from the main loop, all this functions works fine. Only in any ISR is no function.

 

Can you give support?

 

Thank you,

Robert.
