STM32H723VE Ethernet

[GTrin.2]

Hello,

I'm using the STM32H723VE chip in my project and I'm having some difficulties getting the Ethernet interface fully functional. Used this chip with the KSZ8041 and I'm giving ping. I enabled the D-Cache and I-Cache, performed the MPU settings. I'm trying to implement the Modbus TCP protocol, I open and close the TCP connection, it works for a while and then it stops working and then it doesn't work anymore. I'm a few things on the forum, however nothing has yet worked.

I use STM32Cube FW_H7 V1.11.0 (6.8.0).

Some relevant settings:

 *(.TxDecripSection)

 . = ABSOLUTE(0x30000100);

Hello @GTrin.2​ ​ and welcome to the Community 🙂,

Please follow this article "Ethernet not working on STM32H7x3", it may resolve your problem.

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

This FAQ will help you to configure your project in STM32CubeMX .

Also, you can get started with the example provided here STM32H7-LwIP-Examples.

I hope this help you!
