[ajaygore]

I want to communicate over RS485 using TWR- MCF32259 and  TWR-SER board .I am using MQX 4.2 and CodeWarrior v11 .I have tried Ethernet to serial example on RS232 my full duplex communication working but As I changes jumper setting for RS 485 I can only transmit data cant receive.There is no RS485 example for TWR-MCF32259 available in MQX4.2

Hi Ajay:

Yes, there is no example on rs485 for MCF32259.

I think you can contact with Embedded Access,  the owner of MQX, to see if they have more information for your case

Embedded Access – MQX Design, Products, & Services 

Anyway, you can refer to the following thread.

RS485 Flow control on ColdFire 54415 

RS485 on 52259 MQX 3.8 

I hope it helps

Regards

Daniel
