Hello, I am using the s32k344 motor driver code and have several prototypes. I found that one of the CAN machines will go offline after running for a period of time, and both sending and receiving will be abnormal. I turned on offline reply and found that the message will lose frames for 200ms. I exchanged CAN transceivers, but the same phenomenon still exists. I have read the errata manual, is it the chip itself that has this bug    E:\S32K344_48V_EAC\MCSPTE1AK344_PMSM_FOC_2Sh_ll

Hi@qicbeng

The example code "MCSPTE1AK344_PMSM_FOC_2Sh_ll" does not provide FLEXCAN functionality; you must have added CAN-related functionality yourself.

Please provide your CAN test project so I can check if your configuration is correct.
