Hello Team,
I am currently utilizing the SPC58EC Microcontroller in an Autosar project where I have set up the CAN MCAL driver for both Tx and Rx operations in interrupt mode. We have noticed that whenever the system bus experiences a sending bus load of around 13%(FD and Normal CAN messages are present), the CAN controller which is supported with FD configuration enters a Bus Off state, and this appears to be an intermittent issue . We have two channels configured: one for FD and the other for standard CAN message transmission, with the sample point set at 80%.
When the same software is executed without 2 to 3 necessary messages, the Bus Off state does not occur. SBC TLE 9271 is used as Can Transceiver
