I am currently using the S32K144. I would like to know how to set the CAN read_only_mode. Also, I want to know why I can’t receive bus messages under the read_only_mode.

Hi,

refer to Listen Only Mode, set by CRTL1[LOM] bit. In this mode more nodes must be connected to the bus as messages not acknowledged is not received in LOM mode.
