Here there are two LIN frames : ID 31 - Request Frame , ID 33 - Response Frame
I'm able to send the Lin Request frame from CANoe and I'm getting the proper response frame from S12 ECU.
But, while transmitting the frame from CANoe it is showing some error. Please see the attached Image.
I want to know why it is showing and how to resolve this.
Thanks & Regards
Okay, But I think the issue is from the ECU side. Because when I disable the response frame from the ECU code, there is so such errors visible on CANoe,
Additionally I'm able to clear the unexpected break while waiting for checksum field error, by adding the delay in ECU code as show below
Now, I'm just getting the framing error while waiting for checksum field error. Is there any way to solve this
Thanks in advance
I think that it would help to see the frames on an oscilloscope.
I understand you don't use NXP LIN Stack, it is your own implementation, right?
Which S12 MCU do you have?
Okay. I'll scope it.
Yes Its own implementation , we have used ZVML Bootloader code for reference LINK
We are using ZVML64 MCU.
