-## 简介
-
-本文档为 NUCLEO-F767ZI 开发板的 BSP (板级支持包) 说明。
-
-主要内容如下：
-
-- 开发板资源介绍
-- BSP 快速上手
-- 进阶使用方法
-
-通过阅读快速上手章节开发者可以快速地上手该 BSP，将 RT-Thread 运行在开发板上。在进阶使用指南章节，将会介绍更多高级功能，帮助开发者利用 RT-Thread 驱动更多板载资源。
-
-## 开发板介绍
-
-NUCLEO-F767ZI 是st推出的一款基于 ARM Cortex-M7 内核的开发板，最高主频为 216Mhz，该开发板具有丰富的板载资源，可以充分发挥 STM32F767 的芯片性能。
-
-开发板外观如下图所示：
-
-
-
-该开发板常用 **板载资源** 如下：
-
-- MCU：STM32f767，主频 216MHz，2MB FLASH ，512KB RAM ，16K CACHE
-
-- 常用外设
- - LED ：3个，LED1 (绿色，PB0),LED2（蓝色，PB7），LED3（红色，PB14）
- - 按键：2个，B1（用户按键，PC13），B2（复位引脚）
-- 常用接口：USB 转串口3、以太网接口
-- 调试接口：ST-LINK
-
-开发板更多详细信息请参考ST [NUCLEO-F767ZI开发板介绍](https://www.st.com/en/evaluation-tools/nucleo-f767zi.html)。
-
-## 外设支持
-
-本 BSP 目前对外设的支持情况如下：
-
-| **板载外设** | **支持情况** | **备注** |
-| :-----------------| :----------: | :-------------------------------------|
-| USB 转串口3 | 支持 | |
-| 以太网 | 暂不支持 | 即将支持 |
-| **片上外设** | **支持情况** | **备注** |
-| GPIO | 支持 | PA0, PA1... PK15 ---> PIN: 0, 1...144 |
-| UART | 支持 | UART3 |
-| **扩展模块** | **支持情况** | **备注** |
-| 暂无 | 暂不支持 | 暂不支持 |
-
-## 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 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 仿真器下载程序，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，LED 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），复位设备后，可以看到 RT-Thread 的输出信息:
-
-```bash
- \ | /
-- RT - Thread Operating System
- / | \ 4.0.0 build Jan 9 2019
- 2006 - 2018 Copyright by rt-thread team
-msh >
-```
-### 进阶使用
-
-此 BSP 默认只开启了 GPIO 和 串口3 的功能，如果需使用 Ethernet 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=mdk4/mdk5/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)。
