    Hi lin,

    Have you checked the initialization settings?

    Are you using the examples provided in the below location ?

    Can you check the Autobaud detect example ?

    Do all the sci examples show this issue of changing baudrates ?

    Ideally once fixed at initialization , the baud should change well within the tolerance but not drastically .

    Regards.
