[imx6] RS422 could be supported on Imx6 series ?

[keres_kim]

HI Developers ~

Good days ~~

simple question. Imx6 chipset could support RS422 serial communication ?

Reference manual said that imx6 support rs232 and rs485, but Nothing mentioned to rs422.

That is why I wonder rs422 could be supported or not.

Does anyone know rs422 on imx6, please leave your comment below ~~

Thank you.

Hi keres

RS422 can be used with i.MX6, standard only defines signal levels so

one can use RS232 to RS422 converter

RS-422 - Wikipedia, the free encyclopedia

Best regards

Hi Igor,

Thank you for your answer.

You're right. imx6 works well with RS422 transmiter.

TX is working well, But Still RX(from PC to target) is not.

Do you have any idea ? I just type like "cat /dev/ttymxc3" and wait the data, but nothing comes in.
