System Workbench for STM32

hi Srinivasan ,
you link was useful and am facing same issue on STM32F417.
I used STM32 Cube Mx to generate the code for LAN8720A.
I have followed your setting here :
i have set PHY_Address = 0
PHY Special Control/Status register Offset - 0x1F
PHY Speed Mask - 0x0004
PHY Duplex Mask - 0x0010
PHY Interrupt Source Flag Register Offset - 0x001D
PHY Link Down Interrupt - 0x0010

i have attached the screenshot of cubemx settings
With this current setting i am not able to get reply for ping request.
(hardware is tested with ping by other hex code).
Can you help me to fix up this issue ?
