STM32H747-ST-DISCOVERY BSP (Board Support Package) Execution Instruction
中文页 |
Introduction
This document records the execution instruction of the BSP (board support package) provided by the RT-Thread development team for the STM32H747-ST-DISCOVERY development board.
The document is covered in three parts:
- STM32H747-ST-DISCOVERY Board Resources Introduction
- Quickly Get Started
- Advanced Features
By reading the Quickly Get Started section developers can quickly get their hands on this BSP and run RT-Thread on the board. More advanced features will be introduced in the Advanced Features section to help developers take advantage of RT-Thread to drive more on-board resources.
Board Resources Introduction
The STM32H747-ST-DISCOVERY is a development board that contains a ARM Cortex-M7. The maximum main frequency is 480 MHz, and it has a wealth of on-board resources that can take full advantage of the STM32H747's chip performance.
The mainly-used resources of this board are shown as follows:
- MCU: STM32H747
- Main Frequency 480MHz
- Memory: 2MB FLASH, 1MB RAM
- Common-used peripherals: USB、Ethernet、arduino API etc.
- Debug interface: Standard JTAG/SWD.
For more details about this board, please refer to the ST official documentation STM32H747I-DISCO。
Peripheral Condition
Each peripheral supporting condition for this BSP is as follows:
| On-board Peripheral | Support | Remark |
|---|---|---|
| USB | Support | |
| On-chip Peripheral | Support | Remark |
| GPIO | Support | |
| UART | Support | UART1 |
Execution Instruction
Quickly Get Started
This BSP provides MDK 5 and IAR projects for developers and it supports the GCC development environment. Here's an example of the MDK5 development environment, to introduce how to run the system.
Hardware Connection
Use a USB cable to connect the development board to the PC and turn on the power switch.
Compile and Download
Double-click the project.uvprojx file, to open the MDK 5 project (MDK requires to download V 5.29 and above to support ST-LINK V3), compile and download the project to the board.
By default, the project uses the ST_LINK simulator to download the program, when the ST_LINK connects the board, clicking the download button can download the program to the board.
Running Results
Once the project is successfully downloaded, the system runs automatically, and LED will flash.
Connect the serial port of the board to PC, communicate with it via a serial terminal tool (115200-8-1-N). Restart the board and the startup information of RT-Thread will be observed:

Advanced Features
This BSP only enables GPIO and serial port 1 by default. If you need more advanced features, you need to configure the BSP with RT-Thread ENV tools , as follows:
- Open the env tool under BSP.
- Enter menuconfig command to configure the project, then save and exit.
- Enter pkgs --update command to update the package.
- Enter scons --target=mdk4/mdk5/iar command to regenerate the project.

Notes
-
Debug serial port has the mapping description for serial port 1.
PA9 ------> USART1_TX
PA10 ------> USART1_RX
