AM2432: EIP stack seems to be not working normally though dp83822 has been negotiated successfiully with pc

Part Number: AM2432
Other Parts Discussed in Thread: DP83826E

Hi experts，

Firstly,the EIP scanner in pc can works normally with the AM243x_LP running as a EIP adapter.

Secondly,I used the same scanner and made it work with my board which selects AM2432 and dp83822.The program in board is changed from that in AM243x_LP.

And dp83822 can be detected by the pc and negotiated at 100MHz successfully.

Here it is:

However,the problem is the board excutes and uart logs in ccs doesn't show any info about 'Forward open Connection' .

Here is the latter part of the uart logs by AM2432 board:

    If the problem is still related with the PHYs,what can I do to verify it?

    Hi Ashwani，

    I think it helpful to add these info.

    The info about REG in logs is read and output in function 'CUST_PHY_DP83826E_setMIIMode' which is excuted in the initial process of dp83822.

    Because when the initial period has been away,I could not use these phy_read or phy_write function.

    From the logs,we can find :

    BMCR  0x7849;

    SOR1   0x2001;

    SOR2   0x0000.

    However,the value of SOR1 does not seem to match my hardware configuration.Is it related with the time of the read-execution?

    Can you give me some advice?Thank you.

    If more info are needed,please do not hesitate to tell me.

    Thanks sigong,

    Which SDK you are working on ?

    I understand that you are facing the problem when running EIP on custom PHY.

    You are not facing any problem while executing EIP on AM243-lp and AM243-evm out of box. correct ?

    Thank you for the response.

    The SDK in use is ind_comms_sdk_am243x_09_00_00_03.

    And there is no problem currently while executing EIP on AM243x-lp.

    Regards

    Hi Ashwani,

    I'm sorry for some wrong info because of wrong operations.

    I changed the PHY's address ,rectifyed and executed the READ operation until the link-status LED is on.

    Here is the latest logs:

    About PHY 3:

    BMCR  0x786D;

    SOR1  0x3FC3;

    SOR2   0x0000.

    Maybe that is helpful to locate to the key point.Thank you.
