    Hello,
    Please clarify: Are you asking about the integrity of the data stored in flash? Power On Self Tests (POST) are used to check the integrity of this data. The POST functionality in iMOTION (with firmware v1.3.3) is UL 60730-1 Class B certified (UL file number: E498177).
    The views expressed here are my personal opinions, have not been reviewed or authorized by Infineon and do not necessarily represent the views of Infineon.

    Thanks for your reply!
    Every software has a CHICHKSUM, which is equivalent to the identification code of the software.How to query?
    This is what UL engineers want, but it is not necessarily required. Because our UL engineers have not experienced infineon's imotion chip to make products.
    Could you please elaborate on the details of the UL process. The POST you mentioned is also very important. How do you let UL know this?

    The UL engineer can look up our file number and the associated documentation.
