Hi，

I have used CAN0 for Freemaster communication in S32K144，and it workes. Howerver, when I use CAN2 for Freemaster communication in S32K44, it doesn't work.

What I changed comparing to using CAN0 is below:

#define FMSTR_CAN_BASE 0x4002B000UL /* FlexCAN2 base on S32K14x */

CAN2->MCR |= (CAN_MCR_FRZ_MASK | CAN_MCR_HALT_MASK);
CAN2->MCR &= ~CAN_MCR_MDIS_MASK;
while((CAN2->MCR & CAN_MCR_FRZACK_MASK ) == 0){}
/* Disable abort mechanism MCR[AEN] = 0 */
CAN2->MCR &= ~CAN_MCR_AEN_MASK;
/* Enable the FlexCAN module */
CAN2->MCR &= ~(CAN_MCR_FRZ_MASK | CAN_MCR_HALT_MASK);

Would you like to point out where I maight wrong?

Thanks a lot!
