i.MX UART hardware misbehaves on baudrate mismatch

Dear all,


Now, we have a issue in the product using i.MX6SX.


I searched it in this community, and I found any same issues as follows:

i.MX6 infinite loop in uart driver(rx interrupt) 

i.MX6 UART hardware misbehaves on baudrate mismatch 


It is an issue to continue receiving 0xFF as well as these reports, although there is no data reception.

As shown in the following figure, general UART communication has Start bit and Stop bit.



When receiving continuous data, can't the UART block for i.MX detect Start-bit and Stop-bit?


Best Regards,
