Question, i.MX6 UART re-initialization

Dear TIC team,


I would like to ask about re-initializing of i.MX6 UART.

My customer is using i.MX6S UART and they need to change UART settings in their application.

When they implemented the re-initialization software without disabling interrupt, they saw the UART did not work as expected after the re-init due to the behavior of interrupt.

Then they added disabling RX interrupt before the re-init process, and UART worked fine after the re-init.

Could you show me whether the adding disabling RX int right before the re-init is reasonable?
