The RS485 communication work on my board with imx233 but to transmit or receive I have to control manually by GPIO (pin set 1 - TX, set 0 - RX). Where can I add to DUART driver some line to set the gpio before transmit and reverie?
which bsp are you using?
What is the bsp?
I use Linux kernel 3.13-rc4 on imx233 (own board).
Oh that is my old thread . I wrote that when I try do it on old kernel. Now in new kernel I want to do it by modify the mxs-auart.c file.
