Port mapping for UART with custom carrier board

Hopefully a simple question:
I developed a custom carrier board that uses the pins for UART0 with flow control (99, 101, 103, 105) as well as UART1 without flow control (203, 205). I believe I’ve updated the device tree properly, but I’m not sure which port /dev/tts*** to use to try to connect the serial devices.

Is there any documentation for this?

hello jsuffolk,

please refer to this topic, Topic 153941.
it shows an example of ttyTHS*, and UART* serial port mappings.
thanks
