Hi,
there are some projects in SDK examples:
c:\NXP\S32DS_ARM_v1.3\S32DS\S32_SDK_Beta_0.9.0\examples\S32K144\demo_apps\FlexCan\
Release of SDK EAR 0.8.2 is compatible with UJA1169 and MC33903/4/5.
There was MC33903 on first version of EVB (S32K144 rev1 was used). Next version of board (with S32K144 rev2) uses UJA1169 to improve CAN-FD capabilities - this is the one you have.
In next release BETA 0.9.0 the support of MC33903/4/5 is removed.
Regards,
Lukas
