TM4C1294KCPDT: Ethernet data mismatch

Part Number: TM4C1294KCPDT


Hi Team,

We are seeking your help with the issue encountered by our customer with the ethernet of TM4C1294. Please see the details of the issue below.

I am facing some issue when I connect the ethernet cable after that received data mismatch. I refer the schematic of the your TM4C1294 evaluation board. When I connect the ethernet via PC and I send the command via ethernet after that received the data but data is not proper received so I removed the cable after that received data is properly. 

We have face issue when we apply 5Hz freq so data will come 5A 6B 5B 6B where 5 raising edge other 5 is falling  but but data come different means sometimes 5, 6 like that but when I remove ethernet cable then data will come proper means 5.

We check all things regarding ethernet section like schematic, layout, protection everythings is good.
