TMS320F28P650DH: ethercat not able to make it work on PORT 1 on control card

Part Number: TMS320F28P650DH
Other Parts Discussed in Thread: SYSCONFIG, C2000WARE

Tool/software:

Hi everybody , 

I m using controlCARD  of P65 and need to have a ring so PORT1 must be working too .

When I run on control card  , port0 is functional but port1 is NOT functional.

This means that when I connect to a master, I can see the first device. Yet when I connect more devices downstream, I cannot see them. 

In Sysconfig,I have configured the pin mux according to the schematic of the eval board. I have not been able to successfully build any of the ethercat examples from C2000Ware as they seem to be designed for the LaunchXL board, or the 2838x variant. After a day of reading the technical reference manual, I cannot find anything clearly wrong with my CCS project. please  can you help me enable port1 so I can properly establish an ethercat ring?

thank you

    Hi Carlo,

    Which C2000WARE SW example are you using? The SW examples are all configured for the ControlCARD by default and should just work directly without changes.

    You are following along with 'EtherCAT_SubordinateDevice_Controller_Software_User_Guide.pdf' in directory below?

    What revision of PCB do you have? Maybe you are using an older version that had some issue.

    Best,
