Hello NXP expert， We are using MPC5777CEVB and MPC57XXMB. IDE:s32ds for Power Architecture OS:Windows 10 Is there any FPU test example base on s32ds? If not, how to enable FPU step by step? Regards, Jinus

Hello,

this core does not have HW floating point unit.

You have to enable it in MSR core register before use of FPU instrucitons:

You can follow the guide how to setup S32DS for EFPU generation here where is also an example code:
