Other Parts Discussed in Thread: MIO, DP83867IR

In our card we have connected ENET 0 to two different PHY IC’s DP83640TVV/NOPB (@EMIO pins for 100Mbps operation) and DP83867IRPAPT (@MIO pins for 1Gbps operation).

Till now we have been working on DP83640TVV/NOPB.

For further up gradation purpose we are trying to use DP83867IRPAPT PHY IC ( By Texas instruments) for 1Gbps Ethernet  operation in ZYNQ (XC7Z030-1FBG676I) @ MIO pins in 16 to 27 (ENET 0). Please suggest the changes that need to be made in code to make it working.

    Hello,

    DP83867IR is a gigabit part and has a variety of featuers and fucntions. These features can be controlled through straps and register settings. The software would need updates to access the registers respective to the desired functions. More information regarding the functions and registers is found in the datasheet. Are there any specific features that you had questions about?

    I would also like to point you to our linux driver for DP83867: http://www.ti.com/product/DP83867IR/toolssoftware This driver has basic functionality and can be used to develop software to fit your final application.

    -Regards,

    Aniruddha
