Hello everyone,
I am working with the NUCLEO-H723ZG board and attempting to establish Ethernet communication using TCP/IP. The firmware was built and flashed successfully using STM32CubeIDE version 1.19.0.
However, I am facing issues with basic network connectivity. Below are the details of my setup and observations:
Setup Details
Board: NUCLEO-H723ZG
IDE: STM32CubeIDE v1.19.0
Ethernet stack: LwIP
PHY interface: RMII
Flashing tool: ST-LINK (onboard)
Test performed: Ping test from PC
Observed Behavior
The Ethernet port LEDs (orange and green) remain solid ON after connecting the Ethernet cable.
Ping requests consistently fail (Request timed out).
No response is received from the board.
Troubleshooting Already Performed
Tested both Static IP and Dynamic IP (DHCP) configurations.
Verified IP address, subnet mask, and gateway settings.
Tried multiple Ethernet cables to rule out cable-related issues.
Rebuilt and reflashed the project multiple times.
Verified that the firmware flashes successfully and runs without build errors.
Despite these steps, the board does not respond to ping requests.
Questions / Assistance Required
Does solid ON state of both Ethernet LEDs indicate a known PHY or clock configuration issue?
Are there any known issues with RMII_REF_CLK configuration on the NUCLEO-H723ZG?
Are there specific CubeMX clock, MPU, or cache settings required for reliable Ethernet operation on STM32H723?
Any recommended minimal or verified example project for Ethernet ping testing on this board?
I need some guidance or suggestions to identify and resolve this issue.
