The UM is confusing wrt UART mapping.
I've used the pin mapping tool.
Does this look correct.
Ball | FUNCTION | WRT i.MX8 | |
UART1 | AD6 | RX | input |
AJ3 | TX | output | |
AJ17 | RTS | output | |
UART2 | AF6 | RXD | input |
AH4 | TX | output | |
AF18 | RTS | output | |
AJ18 | CTS | input | |
UART3 | N25 | RX | input |
L26 | TX | output | |
AE20 | RTS | output | |
UART4 | AH21 | RX | input |
AJ21 | TX | output | |
AJ22 | RTS | output | |
AH20 | CTS | input |

Hi,
Thank you for your interest in NXP Semiconductor products,
I've configured a project myself and your pinmux doesn't have any conflicts, registers modified match with the reference manual, you can proceed.
Regards
