s32k118 lin error

mose — Thu, 23 Nov 2023 08:25:46 GMT

Hi team

based on s32k118, ide is s32ds, generate lin code by lin example(lin_baremetal_slave)

However, during normal communication with the master, an error frame occurs as follows

Here there are two LIN frames : ID 1 - Request Frame , ID 2 - Response Frame

During normal communication with the master, an error frame occurs as picture

1) CSerror(checksum error)

2) RCverror(8 bytes of data, but only 1 to 2 bytes of data sent)

Is there a solution to the error?

Thanks & Regards

Just to confirm, can you give me the name of Lin Example?

Also please provide the name of RTD package version that you're using. And how can you test/observe this issue?

Thank you,

Nam.

I checked the example and saw the Rx Buff receive data correctly when i press button for sending.

I tried to observe the data with DS tool few times and there's no error happens.

I checked with lin_slave and lin_master example from DS 2.2 SDK 3.0.0

Please help me to check it again.

Thank you,

Nam.

I think there're 2 points that you can try with your app:

- Increase the TIMEOUT param from the code

- Update the DS to update 2 and try the newer version of SDK.

Thank you,
