S32K344 EMIOS LCU timestamp model

Dear, I'm sorry.

When using the following routine to change the ICU timestamp mode from linear to cyclic, the customer test found that there will be occasional abnormal data, as attached, please help to identify the problem? Thanks for your help!

Hi@scott071209

I tested it on the S32K344EVB as you modified it and I ran it for a while I didn't notice any problems.

I don't know how the customer exported these values for analysis, it could be a problem with interference in the connecting wires or something like that.

If the client can reproduce it 100%, I can test it again the way he did.

sorry, update picture(is fault timestamp) .

customer use S32K344 EVB, and change LCU timestamp model.(form linear to circle). and change program buffer size from 10u to 128U.

Please see attachment.

Hi@scott071209

Have your client provide specific test environments as well as screenshots of test errors.

For example, what hardware was tested, what was modified, screenshots of the results of the test errors, etc. I can't pinpoint the cause of the problem based on your description.

Secondly, is the second image you provided relevant to the question?
