由 google Understanding the STM32CubeMX for STM32MP135d with ETH Configuration
Are you working on a project with the STM32MP135d microcontroller and need to configure the Ethernet (ETH) interface? Look no further! In this detailed guide, we will walk you through the process of setting up the ETH interface using STM32CubeMX, a powerful configuration tool for STM32 microcontrollers.
Adding the ETH Device
Before you start, ensure that you have STM32CubeMX installed on your computer. Open the tool and create a new project or open an existing one. To add the ETH device, follow these steps:
- Click on the “Add Device” button in the left panel.
- Select “STM32MP1 Series” from the list of devices.
- Select “STM32MP135D” as the device variant.
- Click “OK” to add the device to your project.
Configuring the ETH Device
Once the device is added, you will see a list of available peripherals. To add the ETH device, follow these steps:
- Click on the “ETH” peripheral in the list.
- Check the “Enable” box to enable the ETH device.
- Select the appropriate PHY interface (MII, RMII, or RGMII) based on your hardware configuration.
- Configure the ETH reference clock input, if necessary.
- Configure the ETH clock source, such as PLL4P or PLL3Q.
- Configure the ETH pins according to your board’s requirements.
Generating Code
After configuring the ETH device, you can generate the code for your project. STM32CubeMX will automatically generate the necessary code for the ETH peripheral. You can also configure additional settings, such as the optee and uboot configurations, as needed.
| Configuration | Description |
|---|---|
| optee | Configure the optee settings, such as the clock source and security protocols. |
| uboot | Configure the uboot settings, such as the boot sequence and network configurations. |
| linux | Configure the linux settings, such as the kernel version and network configurations. |
Bringup and Testing
After generating the code, you can upload it to your STM32MP135d board and test the ETH interface. Ensure that your board is powered on and connected to a network. You can use a network tool, such as Wireshark, to monitor the ETH traffic and verify that the interface is working correctly.
Conclusion
Configuring the ETH interface on the STM32MP135d using STM32CubeMX is a straightforward process. By following the steps outlined in this guide, you can quickly and easily set up your ETH interface and start communicating over the network. Happy coding!
