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&nbsp; &nbsp;&nbsp;E:\S32K344_48V_EAC\MCSPTE1AK344_PMSM_FOC_2Sh_ll</P> Sat, 16 May 2026 06:44:31 GMT qicbeng 2026-05-16T06:44:31Z https://community.nxp.com/t5/S32K/s32k344-can/m-p/2366394#M58641 <P>Hello, I am using the s32k344 motor driver code and have several prototypes.
