Hi imx-developers,

Good day !

It's simple. Could imx6 chipset support RS485 ?

There are many related questions posted on this community about RS485.

Many patch codes exist as well but I not sure which one would be trusted.

Would you somebody tell us which patch code works well on rs485 ?

thank you.

Hi keres

RS485 is currently not supported by the imx serial driver, however

some folks seems added RS485 support to the imx serial driver.

Dear Igor,

Thank you for your response.

Patch code from "Marc" is working well.

RS485 TX data has verified successfully,But not RX. I'm still checking on it.

Have a nice day ~~
