How to check CRC error when CRCERR flag is not enabling after getting wrong data/crc?

I am trying to implement SPI protocol using peripheral CRC in STM32F7 nucleo board. In that I have used 8-bit CRC with polynomial = 07.

Even if we are sending incorrect CRC to controller(which is act as a slave), then it’s not enabling CRCERR flag.

Can you please guide me to solve this issue?
