Rock Pi S UART 1 Flow Control

#1

Hi @radxa

I have a Rock PI S V13, I am trying to use UART1 with flow control, I see that there is no overlays for that, could you perhaps assist me in creating a overlay that enables the flow control for UART1?

Hi Sven,

We just added this overlay. Please try with the attached dtbo: rk3308-uart1-full.dtbo.zip (612 Bytes)

Hi @RadxaYuntian,

Thank you for the assistance, I can confirm that this works correctly.

I have one more question, is there some sort of support to configure the UART to work with a half duplex RS485 chip where the UART RTS pin enables or disables the DE pin for the RS485?

You should use a proper TTY to RS485 adapter for this job.

@RadxaYuntian I figured that yes. Thank you for all the assistance
