Hi
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
I'd highly recommend you to refer to the transfer_dma demo in the SDK library, in this demo, it demonstrates the use of the USART module in DMA-driven asynchronous mode to receive characters from a terminal emulator. USART will echo back every 8 characters to the terminal emulator.
Please download the SDK library via the below link.
