Lin Mismatched Values Using LIN Stack

itsnewforme — Wed, 05 Apr 2023 13:48:58 GMT

Hi, I'm using S12 ECU as LIN Slave For Reprogramming using LIN Stack.

Here, For the first request i.e. 02 10 02 00 00 00 00 00 I'm getting a proper response

06 50 02 00 00 00 00 00 ( Refer below image )

Now, For the Second Request 02 27 01 00 00 00 00 00. I'm getting a different response than expected.

On debugging I found out that the array that I'm using to store response is correctly getting filled also the array used by LIN stack i.e. lin_p_frameBuf is also correctly getting filled with data ( refer image below - highlighted in blue )

So, the expected response should be 06 67 01 84 87 00 00 00. But, on Trace Window the data is

06 67 01 59 EB 00 00 00. i.e. first three bytes are okay but next three bytes are different. ( please refer image )

Can you please suggest anything to resolve this issue.

Thanks in advance

BR, Abhijit

Hi @itsnewforme,

Based on your information, I created an example to reproduce the issue. In my example the data will be updated after each successful receipt of Tx_frame.

You can see all of frames that sent on the bus as below:

Please re-check on your side to make sure that you updated the signal correctly.

Use correct configuration files that generated by NCF tool.
l_bytes_wr_LI0_BootLoader_Rx_Frame() to update signal to buffer before it is sent on the bus.

Anyway, you can refer to my example to more detail(Attached).

Software: LIN_stack_S12_4_6_6
Hardware: S12ZVL128

If the issue is still not resolved, please share with me more information about your project.

Best regards,

Dan
