## Introduction
|
||
|
|
|
||
|
|
This document records the execution instruction of the BSP (board support package) provided by the RT-Thread development team for the STM32MP157A-DK1 development board.
|
||
|
|
|
||
|
|
The document is covered in three parts:

## STM32MP157A-DK1 Board Resources Introduction
|
||
|
|
|
||
|
|
The STM32MP157A-DK1 is a development board based on a dual Cortex-A7 and Cortex-M4 core. The Cortex-A7 core operates at 800 MHZ and the Cortex-M4 operates at 209MHZ. There is no Flash inside the STM32MP157A.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
The mainly-used **on-board resources** are shown as follows:
|
||
|
|
|
||
|
|
- MCU : STM32MP157AACx
|
||
|
|
- Common peripherals:
|
||
|
|
- 4 LEDs: LD4(PA14), LD6(PA13), LD7(PH7), LD8(PD11)
|
||
|
|
- 4 Buttons: WAKE_UP, RESET (NRST), USER1(PA14), USER2 (PA13)
|
||
|
|
- Common-used interface: USB, SD card, Ethernet, MIPI, USB HOST, Audio, HDMI, Arduino.
|
||
|
|
- Debug interface: Standard JTAG/SWD.
|
||
|
|
|
||
|

## Execution Instruction
|
||
|
|
|
||
|
|
### Quickly Get Started
|
||
|
|
|
||
|
|
This BSP provides IAR projects for developers. Here's an example of the IAR 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.eww file, to open the IAR project, compile and download the program to the board.
|
||
|
|
|
||
|
|
> By default, the project uses 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
|
||
|
|
|
||
|
|
After the program is successfully downloaded, the system runs automatically. Observe the running results of the LED on the development board, the blue LD8 will flash periodically.
|
||
|
|
|
||
|
|
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 4 by default. If need more advanced features, you need to configure the BSP with RT-Thread Env tools, as follows:
|
||
|
|
|
||
|
|
- Open the [Env](https://www.rt-thread.io/download.html?download=Env) tool under this BSP;
|
||
|
|
- Enter the `menuconfig` command to configure the project, then save and exit;
|
||
|
|
- Enter the `pkgs --update` command to update the packages;
|
||
|
|
- Enter the `scons --target=iar` command to regenerate the project.
|
||
|
|
|
||
|
|
## Notes
|
||
|
|
|
||
|
|
- Before downloading the program, set the board to the mode of "Engineering Mode". The BOOT switch sets to BOOT0=0 and BOOT2=1, as shown below:
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
- If need to reburn the program, please reset the development board.
