Be aware, that you may require even so the CSEC package, that is not part of the MCAL package. You may find it here: https://www.nxp.com/webapp/swlicensing/sso/downloadSoftware.sp?catid=SW32K14-ACSEC421E (be aware that the installer has a bug and create the plugin of CSEC NOT in folder plugins, but in folder eclipse).
Do you have one package of MCAL for the S32K14x that is complete valid? I'm not sure, which package to be selected. A lot of Bugfixes and parts with only one module (e.g. SPI) are listed on the NXP Website...
Following the next link you can find the AUTOSAR 4.2 MCAL for S32K14x:
