Dear Team,

Right now I'm using i.Mx8qxp based custom board.

There I want to develop the Test application to calculate RS-485 data rate.

I'm new to RS-485.

Can any one guide me to move further?

Is there any command or calculation or algorithm to achieve this?

Thanks in Advance.

Thank You.

Best Regards,

J.P.Raja

As the linux BSP for i.MX8QXP do not support, so for the RS 485 using you can use the Sensing IO direction Automatically via hardware, don't need to tune software. The follow is used on i.MX6, you can refer to .
