EK-TM4C123GXL: Using usb-2-MDIO tool to test the DP83620 ethernet PHY

Other Parts Discussed in Thread: DP83620, , USB-2-MDIO

Hello TI,

As per the USB-TO-MDIO tool details a MSP430 Board is needed to interface with the MII pins and get access to the ethernet physical registers.

I need to understand can this be done using a EV-TM4C123GXL and is the process same.

I am trying to access the register of DP83620 ETHERNET PHY.

Thank you .

    Hello Chitransh,

    Unfortunately, this really is a question for the Ethernet forum where you referenced your initial post from rather than our TM4C forum. I will explain why.

    I downloaded the USB2MDIO Tool and reviewed what it provided. It doesn't include any source code, so I don't see any method to use it for TM4C from our perspective. The output files are not going to be compatible with TM4C, and without source code it is impossible to rebuild a project for TM4C MCUs. The reason I mention to ask on the Ethernet forum though is that the Ethernet team which made the tool may be able to offer if there is a TM4C equivalent.

    Hello Ralph,
    Apparently the USB-2-MDIO works with MSP430 launchpad to access the register of DP83620 and the code cannot be ported for EK-TM4C123GXL.

    Thank you for your suggestion.
