MCU-PLUS-SDK-AM243X: How use others Ethernet PHY than DP83869? Such as DP83826I

Hi Chunyang ,

Thanks for your query.

Please follow below documentation and let me know if you need further help?

Hi Ashwani,

       Following your reply, now I know the method how to use a new PHY to replace DP83869.

       About this topic my final questions are the followings.

       Our ARM IC is AM243x_ALV. We intend to use two DP83826 as EtherCAT PHY and two DP83867 as Ethernet PHY in the new PCB.

       1 Please help me to evaluate whether that is all right to have two DP83826 as EtherCAT PHY and two DP83867 as Ethernet PHY to connect to one AM243x_ALV?

       2 On this condition, if 2 Ethernet Ports is not possible, then we have to use only one that is acceptable.

       3 Please guide me to do the System Config to implement this solution: two EtherCAT Ports and two(or one) EtherNet ports.

       4 As well as how to modify the SDK source code to meet this.

Thanks 

Chunyang

Are you planning to use ICSSG or CPSW for EtherCAT (controller or device)?

Are you planning to use ICSSG or CPSW for Etherent and with what speed ?

Hi Ashwani,

   Thanks for your reply, now I'm studying these information.

   For your question,

  We are planning to use ICSSG0 for EtherCAT Slave node and CPSW0 for 2-Ports EtherNet(TCP/IP function).

  I need to work out the solution and help the schematic guy to complete the IO assignment of AM243x.

Thanks

Hi Ashwani,

   Thanks for your help, the guidelines are really what I was expected. Now I could focus on the work.

    On one single core of AM243x_ALV, I am intend to assign 2 EtherCAT ports on PRU-ICSSG0, and 2 EtherNet ports on PRU-ICSSG1.

    I add EtherCAT first and then Enet(ICSS), but there is an error for Enet(ICSS): Number of Rx Ch Index with value '1' should be same as'0'

   Q1: Regardless of whether there is EtherCAT or not, this Error always raises when I add an Enet(ICSS). Should I ignore it, and go ahead?

    And, I could find the ETHPHY Device: DP83869 for EtherCAT as default, I will manage to change it to DP83826 later.

    Q2: My question is where would I find the ETHPHY Device for EtherNet  Enet(ICSS)? I cannot find the part-number anywhere. If I leave all the default settings, and only make sure the Pin assignment is all right, could the new PHY DP83867IS work properly?

Best Regards

Hi Ashwani,

   For your information, I changed my mind like this:  ICSSG0 for EtherCAT Slave node and ICSSG0 for 2-Ports EtherNet(TCP/IP function), as I learned ICSSG and CPSW might not work on a single core.

FYI

Thanks

TI offers evaluation modules (EVMs) for the Sitara processor family with Ethernet PHY solutions using either the DP83867 or DP83869 Ethernet PHY transceivers.
