You should have some code which test MB4 flag if set, which indicates received message into this MB. Or could be called from interrupt if this is enabled for MB4.</P> <P>BR, Petr</P> Wed, 23 Mar 2022 07:03:12 GMT PetrS 2022-03-23T07:03:12Z https://community.nxp.com/t5/S32K/Flexcan-Recieve-message/m-p/1431839#M14533 <P>Hi,</P><P>I am trying to&nbsp; transmit and receive message through CAN.
