Lin Frame Format

itsnewforme — Tue, 27 Dec 2022 06:39:46 GMT

Hi, I'm using NXP Lin stack For S12ZVL64 as Slave. I have created LDF consisting of one bit Tx Signal and one bit Rx Signal.

In DSO, I'm able to Map the Lin Frame Format for both Tx and Rx Frame But, I've few questions

Q.1] I'm able to see consecutive frame on DSO for Tx Frame & Rx Frame. PFA, Is it correct ?

Q. 2] There is continuous set of 1 bit between Tx and Rx frame. What are those and from which part of stack is it coming ?

Thanks in advance

Regards

Abhijit.

Hi itsnewforme,

[Q.1]: I'm able to see consecutive frame on DSO for Tx Frame & Rx Frame. PFA, Is it correct ?

=> I am not sure. Because the frames that were sent on the bus were decided by Master. The master sends the header of the frame(Break, Sync, PID). The slave sends a response(Data, Checksum) if it is publisher of the PID. So, please recheck the master node and your .ldf file to know what the frames are sent.

[Q. 2] There is continuous set of 1 bit between Tx and Rx frame. What are those and from which part of stack is it coming?

=> It is a Lin signal between lin . frames. When do not have any frames on the bus, the LIN bus is always set to high by LIN transceiver.

Best regards,

Dan
