Within callback you use function for receiving into MB, moreover MB7, which is occupied by RXFIFO filter table. So try to use FLEXCAN_DRV_RxFifo(INST_CANCOM1,&amp;<SPAN style="color: #51626f; background-color: #ffffff;">gsCAN_RXMsg</SPAN>);</P><P></P><P>BR, Petr</P></BODY></HTML> Thu, 06 Jun 2019 10:20:51 GMT https://community.nxp.com/t5/S32K/How-to-configure-FlexCAN-to-avoid-FLEXCAN-EVENT-RXFIFO-WARNING/m-p/936650#M4997 PetrS 2019-06-06T10:20:51Z
