Hi,
if you use SDK drivers, take a look at SW example available in the installation folder:
c:\NXP\S32DS.3.4\S32DS\software\S32SDK_S32K1XX_RTM_4.0.1\examples\S32K144\driver_examples\system\crc_checksum\
Description can be found in the user manual available here:
c:\NXP\S32DS.3.4\S32DS\software\S32SDK_S32K1XX_RTM_4.0.1\doc\
If you don't use SDK, you can check this application note, CRC example is included:
