AM2434: the end of CAN frame level width error

Bruce(Shanghai) Liu

Part Number: AM2434

Hi team,

This figure shows the end of CAN signal. The yellow is CANH, the blue is chip tx pin, and the last level is more than 24us. The bus is 500K. This level width obviously does not meet the 11898 standard, which will cause other ECUs detect errors.

Hey Bruce,

Can you provide more details regarding the CAN system implementation/expectations?

Is Classic CAN being used, or CAN-FD with bit-rate switching, or CAN-FD without bit-rate switching?

Can you provide a register dump of your MCAN_CFG register settings for reference?

Thank you.

Best Regards,

Zackary Fleenor
