How to send and receive UDP packets on the Nucleo-H723ZG board?

[Daecheol]

I am trying to use LWIP on the STM32H723 Nucleo board to send and receive UDP packets. I have generated code using CubeMX version 6.70 and configured it to use LWIP with FreeRTOS. I have referred to the H7 series LWIP related problems and H723 address setting problems in this community. But when I run the project, it triggers the MemMange_Handler(void) and no longer proceeds. I believe the issue may be with the MPU configuration. If I don't set up MPU, the project runs, but I can't send or receive UDP packets. When I check packets using WireShark, I can only see ARP protocol when sending UDP packets. I would appreciate it if you could tell me the solution.

Hello @Daecheol​ and welcome to the Community 🙂,

I advise you, when you configurated the LWIP, to get inspired form the steps described in this FAQ: How to create project for STM32H7 with Ethernet and LwIP stack working

Also, you can get started with the example provided here stm32-hotspot/STM32H7-LwIP-Examples: Ethernet examples using LwIP + FreeRTOS for STM32H7 Discovery and Nucleo boards (github.com).

I hope this helps!

Thanks for your answer.

I checked the link above and it solved the problem. In stm32H723, MPU setting can be done as shown in the following figure.

 

thank you.
