Part Number: DP83848I-MAU-EK
Other Parts Discussed in Thread: USB-2-MDIO

Hi,

I am using with MSP430G2 and DP83848 MAU combine . The MAU came with default at 100Mbps. The script in USB2MDIO tool set for 100Mbps. I tried change it to 10M. Not work. I had also tried to write to register 0x00, 0x1a, 0x1b and 0x19 one at a time but the speed is the same. Can someone help?

    Hi Hung,

    You should verify your USB-2-MDIO tool is working.

    Try using the find PHY ID function in the File menu, to ensure your USB-2-MDIO is detecting a PHY at the address you choose.

    Then make sure the selection for extended register access is set to "No". DP83848 will not respond to extended register access.

    Best Regards,
