AM6422: DP83620 driver

Wendy
Intellectual 860 points

Part Number: AM6422
Other Parts Discussed in Thread: DP83620, , SYSCONFIG

Tool/software:

Hello!

I use the AM6422 CPU and the DP83620 chip to connect to the ICSSG Ethernet in RTOS. Use  MII mode,there is currently no corresponding PHY driver,Can you provide a corresponding PHY driver? Is the general PHY driver applicable? How to add a new PHY driver?

Thanks!

    Hi ,

    Thanks for connecting with TI.

    How to add a new PHY driver?

    Please follow below documentation for custom PHY integration.

    AM243x MCU+ SDK: Ethernet PHY Integration Guide

    AM243x MCU+ SDK: Enet Integration Guide

    Let me know if you need further help.

    Regards

    Thanks for your answers！

    I also have an problem。

    1、Can you provide the corresponding DP83620 driver source code?

    2、I am using CCS development environment to configure sysconfig. When configuring ICSSG, pin configuration crossover occurs (hardware design issue). PR0_MII0_MR0_CLK, PR0_MII0_MT0_CLK, PRG0_MDIO0_MDC, PRG0_MDIO0_MDIO belong to the ICSSG-1 device, but the other signals are on ICSSG-0. Is this correct?

    3、When I use the ICSSG0 pin, some error occurs after compiling，like“ICSSG_DUALMAC_PORT_1_HOST_POOL_SIZE  Undeclared”

    Could you help me identify where my problem is?

    Thanks！

    Can you check with latest MCUSDK release MCU-PLUS-SDK-AM64X Software development kit (SDK) | TI.com and confirm you are facing problem there as well ?

    Wendy said:
    Can you provide the corresponding DP83620 driver source code?

    You can create a separate thread and we will connect you with PHY team for this.

    HI,

    I have updated the new MDK, and the previous compilation error problem has been solved. There are two more questions I need to confirm with you: 

    1. On the updated MDK, CPSW and ICSSG still cannot be used at the same time, is that right?

    2. Is there a MII mode Ethernet configuration example for ICSSG that I can refer to?

    Regards

    Hi ,

    As the original problem is solved here can you please raise separate thread for each query.

    It will help us and wide audience to track the issues.

    Regards
