+# STM32MP157A-EV1 BSP (Board Support Package) Execution Instruction
+
+[中文页](README_zh.md) |
+
+## Introduction
+
+This document records the execution instruction of the BSP (board support package) provided by the RT-Thread development team for the STM32MP157A-EV1 development board.
+
+The document is covered in three parts:
+
+- STM32MP157A-EV1 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.
+
+## STM32MP157A-EV1 Board Resources Introduction
+
+The STM32MP157A-EV1 is a development board based on a dual Cortex-A7 and Cortex-M4 core. The Cortex-A7 core operates at 650 MHZ and the Cortex-M4 operates at 209MHZ. There is no Flash inside the STM32MP157A.
+
+![board](figures/board.png)
+
+The mainly-used **on-board resources** are shown as follows:
+
+- MCU : STM32MP157AAAx
+- Common peripherals:
+  - 4 LEDs: LD4(PD8), LD5(PD9), LD2(PA13), LD3(PA14)
+  - 4 Buttons:  WAKE_UP, RESET (NRST), USER1(PA13), USER2 (PA14)
+- Common-used interface: USB, SD card, Ethernet, MIPI, USB HOST, Audio, HDMI, Arduino.
+- Debug interface: Standard JTAG/SWD.
+
+For more details about this board, please refer to the ST official documentation:
+
+[STM32MP157A-EV1 Development board introduction](https://www.st.com/content/st_com/zh/products/evaluation-tools/product-evaluation-tools/mcu-mpu-eval-tools/stm32-mcu-mpu-eval-tools/stm32-eval-boards/stm32mp157a-ev1.html)

+## Execution Instruction
+
+### Quickly Get Started
+
+This BSP provides MDK4,MDK5 and IAR projects for developers. Also support 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 MDK5 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 orange LD4 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:
+
+```bash
+ \ | /
+- RT -     Thread Operating System
+ / | \     3.1.1 build Nov 19 2018
+ 2006 - 2018 Copyright by rt-thread team
+msh >
+```
+
+#### Drivers
+
+##### 1. DAC
+
+- Open the [Env](https://www.rt-thread.io/download.html?download=Env) tool under this BSP;
+- Enter the `menuconfig` command, enter the Hardware Drivers config and open DAC, save and exit;
+- Enter the `scons --target=iar` command to regenerate project.
+
+###### Finsh
+
+Before you use a device, you need to find out if the device exists, and you can use the name of the DAC device that is enrolled with the command  `dac probe` . As shown as follows.
+
+```c
+msh />dac probe dac1
+probe dac1 success
+```
+
+Enable the channel of the device can use the command  `dac enable`  followed by the channel number.
+
+ ```c
+msh />dac probe dac1
+probe dac1 success
+ ```
+
+Set up the data of the channel for a DAC device can use the command  `dac write` followed by the channel number.
+
+```c
+msh />dac write 1 1000
+dac1 channel 1 write value is 1000
+```
+
+Disable the channel of the device can use the command `dac disable` followed by the channel number.
+
+```c
+msh />dac disable 1
+dac1 channel 1 disable success
+```
+
+### 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,BOOT1 = 0 and BOOT2=1, as shown below:
+
+![boot](figures/boot.png)
+
+- If need to reburn the program, please reset the development board.

+## 使用说明
+
+使用说明分为如下两个章节：
+
+- 快速上手
+
+    本章节是为刚接触 RT-Thread 的新手准备的使用说明，遵循简单的步骤即可将 RT-Thread 操作系统运行在该开发板上，看到实验效果 。
+
+- 进阶使用
+
+    本章节是为需要在 RT-Thread 操作系统上使用更多开发板资源的开发者准备的。通过使用 ENV 工具对 BSP 进行配置，可以开启更多板载资源，实现更多高级功能。
+
+
+### 快速上手
+
+本 BSP 为开发者提供 MDK4、MDK5 和 IAR 工程，并且支持 GCC 开发环境。下面以 MDK5 开发环境为例，介绍如何将系统运行起来。
+
+#### 硬件连接
+
+使用数据线连接开发板到 PC，打开电源开关。
+
+#### 编译下载
+
+双击 project.uvprojx 文件，打开 MDK5 工程，编译并下载程序到开发板。
+
+> 工程默认配置使用 ST-LINK 下载程序，在通过 ST-LINK 连接开发板的基础上，点击下载按钮即可下载程序到开发板
+
+#### 运行结果
+
+下载程序成功之后，系统会自动运行，观察开发板上 LED 的运行效果，橙色 LD4 会周期性闪烁。
+
+连接开发板对应串口到 PC , 在终端工具里打开相应的串口（115200-8-1-N），可以看到 RT-Thread 的输出信息:
+
+> 注：正点原子开发板 在使用终端工具如：PuTTy、XShell 时，会出现系统不能启动的问题，推荐使用串口调试助手如：sscom
+
+```bash
+ \ | /
+- RT -     Thread Operating System
+ / | \     3.1.1 build Nov 19 2018
+ 2006 - 2018 Copyright by rt-thread team
+msh >
+```
+#### 驱动使用
+##### 1. DAC
+
+1. 在 bsp 下打开 env 工具；
+2. 输入`menuconfig`命令， 进入 Hardware Drivers config 打开 dac，保存并退出；
+3. 输入  `scons --target=iar` 命令重新生成工程；
+
+###### Finsh
+
+在使用设备前，需要先查找设备是否存在，可以使用命令 `dac probe` 后面跟注册的 DAC 设备的名称。如下所示：
+
+```c
+msh />dac probe dac1
+probe dac1 success
+```
+
+使能设备的某个通道可以使用命令 `dac enable` 后面跟通道号。
+
+```c
+msh />dac enable 1
+dac1 channel 1 enables success
+```
+
+设置 DAC 设备某个通道的数据可以使用命令 `dac write` 后面跟通道号。
+
+```c
+msh />dac write 1 1000
+dac1 channel 1 write value is 1000
+```
+
+关闭设备的某个通道可以使用命令 `dac disable` 后面跟通道号。
+
+```c
+msh />dac disable 1
+dac1 channel 1 disable success
+```
+
+### 进阶使用
+
+此 BSP 默认只开启了 GPIO 和 串口4 的功能，如果需使用 SD 卡、Flash 等更多高级功能，需要利用 ENV 工具对BSP 进行配置，步骤如下：
+
+1. 在 bsp 下打开 env 工具。
+
+2. 输入`menuconfig`命令配置工程，配置好之后保存退出。
+
+3. 输入`pkgs --update`命令更新软件包。
+
+4. 输入`scons --target=iar` 命令重新生成工程。
+
+本章节更多详细的介绍请参考 [STM32 系列 BSP 外设驱动使用教程](../docs/STM32系列BSP外设驱动使用教程.md)。
+
+## 注意事项
+
+1. 下载程序前，将开发板设置为 "Engineering Mode" 模式。 在 DK1 开发板上，将底下的BOOT开关设成 BOOT0=0，BOOT2=1状态，就进入"Engineering Mode"，如下图所示：
+
+   																<img src="figures\boot.png" alt="boot" style="zoom:50%;" />
+
+2. 再次烧写程序时，需要复位开发板。
