UDP not working on STM32H563ZI using NetX Duo UDP Echo Server example

[Kaviya]

Hi,

 

I am using the STM32 NUCLEO-H563ZI board and testing the NetX Duo UDP Echo Server example provided by STM32.

 

Setup:

 

- STM32 NUCLEO-H563ZI

- NetX Duo UDP Echo Server example

- Direct Ethernet LAN cable connection between PC and board

- Static IP configured on both PC and STM32

 

Issue:

UDP communication is not working. When I try to ping the STM32 IP address from the PC, I get "Destination Host Unreachable".

Since I am using the official UDP Echo Server example, I expected the board to be reachable and respond to UDP packets.

Has anyone successfully tested this example on the NUCLEO-H563ZI? Are there any additional Ethernet, PHY, or NetX Duo configurations that need to be checked?

 

Any suggestions would be appreciated.

Hello ​@Kaviya,

Thank you for your report.

Following these steps, it was possible to successfully ping the NetX Duo UDP Echo Server example using a static IP address:
In CubeMX:

• Middleware and Software Packs -> NETXDUO -> Addons: DHCP from "Client" to "Disable".
• Middleware and Software Packs -> NETXDUO -> Configuration: Set NetX Duo Ethernet IP Address to an IP address in the same network as your PC.
• Generate the project.

In app_netxduo.h:

• Remove the include statement for nxd_dhcp_client.h.

In app_netxduo.h:

• The attached file contains the modifications applied to implement the UDP server with a static IP address.

This is not a good choice. Use a hub.
