Part Number: PROCESSOR-SDK-AM62A Other Parts Discussed in Thread: THVD1454 Hi TI Team, We developing our custom board based on AM62A SK EVM. We wan to interface the THVD1454 RS485 Transceiver with AM62Ax processor. Below is the rough hardware design. As per THVD1454 datasheet, DE pin will regulate the direction of transmit and receive of data as RE pin is short with DE. Can we use DE pin as rts-gpio and handle it automatically from the Linux driver? I found am335x-nano.dts reference where RTS GPIO is defined( I am not sure that it is used for RS485 but guessing that it would be used for RS485). &uart1 { pinctrl-names = "default"; pinctrl-0 = ; status = "okay"; rts-gpio = ; rs485-rts-active-high; rs485-rx-during-tx; rs485-rts-delay = ; linux,rs485-enabled-at-boot-time; }; Can same be done for the AM62Ax processor to control DE using rts-gpio? Will UART's RTS able to control the DE line for transmit and receive automatically? Regards, Jay
