Hello, I am designing a carrier board that is using all 3 UARTS (UART0, UART1, & UART2). I am not using the flow control signals UART*_CTS or UART*_RTS on any of these UARTs. Can I just float (no connect) the UART*_CTS inputs to the TX1 or do I need to have pullups on my board to 1.8V? It appear…

UART_CTS#

Just leave CTS/RTS unconnected and keep the default status as Jetson carrier board.
