NUCLEO-H723ZG using Ethernet/Ping Problem

[ADynr.1]

Hello,

I got the NUCLEO-H723ZG board to save ADC data fast enough. I don't have any experience with ETH. So I wanted to begin simply. I tried to use some tutorials and examples but the board doesn't respond to pings.

I tried:

1- The "LwIP_UDP_Echo_Server" example on STM32CubeIDE

2- https://community.st.com/s/article/How-to-create-project-for-STM32H7-with-Ethernet-and-LwIP-stack-working

3- https://controllerstech.com/stm32-ethernet-1-connection/

None of them worked. What should I do? I just want to get ADC data.

Hello @ADynr.1​,

If the Ethernet on your STM32H723 is not sending or receiving data correctly. Or, the IP stack is not able to establish connection to other devices. In this case, it maybe the problem is related to memory layout and Memory Protection Unit (MPU) configuration.

For more details, please refer to this article: Ethernet not working on STM32H7x3.

Hi Imen,

Thank you for your answer.

I checked the website you sent. I tried the example mentioned in the link

"It is strongly recommended to follow the same configuration as in examples provided in STM32CubeH7 package:

e.g. Projects\STM32H743ZI-Nucleo\Applications\LwIP\LwIP_HTTP_Server_Netconn_RTOS."

But unfortunately, I still can't get any response to pings or echo(in the udp echo example). Would it be related to Windows 10?

Also, MPU configurations look correct on the example here but no response to ping on this example too: https://community.st.com/s/article/How-to-create-project-for-STM32H7-with-Ethernet-and-LwIP-stack-working

I tried to ping on another laptop, no response again.

Dumb question, but does your laptop have the same subnetwork mask as your MCU ?
