Hello,

By any chance, are you using the semi hosting option in your project? Could you please confirm that you use the UART one?

Also, just to confirm, which version of the MCUXpresso IDE are you using? Is it the 10.3.1? if it is not that version, could you please try with that one?

Regards,
Estephania

Hello,

Are you cleaning the flags of the UART transactions ?
