Debug UART


I currently designing a carrier board for the TX2.

I would like to know UART0_RTS# (PIN)and UART0_CTS#(PIN) can be left unconnected ?

I just need to use UART0_TX and UART0_RX.

Sure, they can be left unconnected.

Thank you.
Does it affect the debugging function?

No, the flow control is not must.
