RTOS/TDA2EVM5777: changing PHY DP83865 to PHY DP83867IRPAP

Part Number: TDA2EVM5777

Tool/software: TI-RTOS

Background：
Hardware Platform：TDA2x EVM Board
Version：ASSY 516580 REV H
 
Software Platform：SDK
Version：PROCESSOR_SDK_VISION_03_04_00_00
 
Explanation：
Originally，there are two PHY chips (DP83865) on the EVM board. When I intended to design a new board based on the EVM board，I found it’s very hard to buy the DP83865 chip. I want to verify the DP83867 can replace the DP83865 chip, so I designed a seprate new testing board used the chip DP83867IRPAP also from TI. When I removed the connection between the TDA2x chip and DP83865 chip on the EVM board, and then connect the DP83867 testing board, didn’t change any software configuration, I found it doesn’t work, printed “NDK: Link Status: 1000Mb/s Full Duplex on PHY 3”.But it didn’t establish connection successfully with PC. I want to know what can I do, I saw some codes relative with DP83867 in SDK, But I don’t know how can I use them. Can you offer me some solution? Thank you very much!

    Hi Yongliang,

    If there was a connection problem, you wouldn't see the link status message. So, after printing the link status message, did it print the IP address of the EVM? Also, are you using static or dynamic IP?

    Hi Yongliang,

    It's been a while since I have heard from you. Were you able to solve this issue?

    No, I applied a DP83867IRPAP-EVM EVM board from TI, and I recieved it, and then I had a look, I found it's not very easy to solder strap resisitor on the board, and actually I don't understand why the TI can design their EVM board in that way.

    Hi Yongliang,

    In TDA2Ex and some other EVMs, we use the DP83867. To use this PHY, we have to specifically configure the delays for the phy. If you check inside your vision sdk folder you should find this file \ti_components\networking\nsp_gmacsw_4_15_00_00\packages\ti\ndk\j6eco\examples_ipu1\client\j6eco_init.c. You should see a function to configure delays for dp83867.

    You can use the same function in your existing code when you use the custom board. This is the only change in 83867 I suppose. Let me know if this helps :)

    Thank you very much! I will try tomorrow, and I think I get your idea. I also compared my hardware configuration with the evm board which use dp83867. I think I can solve it next. Thank you for your quick reply.

    Hi Yongliang,

    I understand that you're still facing trouble trying to get the PHY to work. Are you facing a HW problem? Have you tried the changes I have recommended

    I think hardware part is OK,and I also tried according your sugesstion, but it still dosn't work.I pasted the hardware board indicator video.

    Below is the log, after I insert the phy delay function into my code, but it still dosn't work. Do you have any suggestions?

    Hi Yongliang,

    Your logs tell me that the connection with the PHY is established. When you say your code isn't working, what exactly is the error? Are you able to get an IP printed in the console?

    I used static IP, and after I insert the PHY delay configuration function in my code, I can't successfully ping(command) with the board(PHY is DP83867), then I used my another board running same code(PHY is DP83865), the PHY DP83865 still can run correctly, I can easily feed video by my labtop to the board, so I guess may be my inserted function dosn't work anymore. I confused. Thank you for your reply!

    Hi Yongliang,

    I believe the configureDelays function might not be getting executed. Can you put a breakpoint inside the function and see if it is hitting? Also, make sure that if there are any SoC specific if conditionals or # defines, comment them out so that the function blindly configures the delays for you.

    I printed some information in the configure delay function, and I saw the information from the initialize Log. I will check the platform related compile option next, after I get the result, I will reply you. I guess may be because of some ethernet related hook, have some limitation on calling the PHY configuration function.Thank you!

    Hi Yongliang,

    Since I have not heard back from you in a long time, I assume you have solved this issue.
