i consider to use s32k 144 mcu.

so we bought 144 evb board and install s32k DS v3.4 & sdk.

but example code not contain rs 485 code, and only have uart.

could you provide sample code about rs 485?

Hi,

as far as I know, no rs485 example is available, and moreover HW flow control is not configurable at all in the SDK, but you can manually set MODIR register.
You can refer to below thread to know how LPUART can be used.
