Hello,
I am using IMX6ULL in uart 2 i was trying to configure RS-485 with gpio as enable pin but i am unable to do so please help me in this its urgent.
Here are the changes i made:
&uart2 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_uart2>;
rts-gpios = <&gpio4 25 GPIO_ACTIVE_HIGH>;
rs485-rts-delay = <0 0>;
status = "okay";
fsl,dte-mode;
};
pinctrl_uart2: uart2grp {
fsl,pins = <
MX6UL_PAD_UART2_TX_DATA__UART2_DTE_RX 0x1b0b1 /* SODIMM 36 */
MX6UL_PAD_UART2_RX_DATA__UART2_DTE_TX 0x1b0b1 /* SODIMM 38 */
MX6UL_PAD_CSI_DATA04__GPIO4_IO25 0x10b0
>;
};
&uart2 {
status = "okay";
rs485-rts-active-high;
linux,rs485-enabled-at-boot-time;
};
