FlexCAN FLTCONF and ACK Error

[raviranjankumar]

Hi All,

I am working on S32K144 FlexCAN driver. I am using SNHVD230 CAN transceiver.  I am communicating with test bench (simulator) which will support CAN. 

When I active the transmit buffer by writing 0xC, the data is transmitting on the bus. I am getting FLTCONF and ACK Error. 

When I communicated with another controller I am getting data from the simulator. I am not getting what is the issue. I configured CAN like given example code in S32K Design Studio.

Please help me. Waiting for your response.

Thanks and Regards,

Ravi Ranjan Kumar

Hi,

I the transmitter expects to get ACK so you always need another node that would acknowledge the message.
