-# RT-Thread for STM32F769-Discovery board
+# STM32F769-DISCO 板级支持包
+## 1. 简介
+
+STM32F769-DISCO 是由意法半导体推出的搭载Cortex-M7内核的高性能单片机的开发板
+包括如下硬件特性:
+
+| 硬件 | 描述 |
+| -- | -- |
+|芯片型号| STM32F769NI |
+|CPU| Cortex-M7 |
+|主频| 216MHz |
+|Flash|2MB|
+|SRAM|512K|
+
+## 2. 编译说明
+
+
+| 环境 | 说明 |
+| ------------ | ------------------------------------------------------------ |
+| PC操作系统 | Linux/MacOS/Windows |
+| 编译器 | arm-none-eabi-gcc version 6.3.1 20170620 (release)/armcc/ |
+| 构建工具 | scons/mdk5/ |
+| 依赖软件环境 | Env工具/(MDK或arm-none-eabi-gcc)/git/调试器驱动 |
+
+1) 下载源码
+
+```bash
+ git clone https://github.com/RT-Thread/rt-thread.git
+```
+
+2) 配置工程并准备env
+
+(Linux/Mac)
+
+```bash
+ cd rt-thread/bsp/stm32f7-disco
+ scons --menuconfig
+ source ~/.env/env.sh
+ pkgs --upgrade
+```
+
+(Windows)
+
+>在[RT-Thread官网][1]下载ENV工具包
+
+4) 生成工程(Mac/Linux下请跳过此步骤)
+
+(Windows MDK5)*
+
+```bash
+ scons --target=mdk5 -s
+```
+
+*该板级支持包不支持生成mdk4的工程
+
+(Windows IAR)
+
+```bash
+ scons --target=iar -s
+```
+
+5) 编译
+
+使用MDK或IAR请参见对应教程
+
+(Windows arm-none-eabi-gcc)
+使用以下指令设置gcc路径
+
+```bash
+ SET RTT_EXEC_PATH=[GCC路径]
+```
+
+(Linux/Mac arm-none-eabi-gcc)
+使用以下指令设置gcc路径
+
+```bash
+ export RTT_EXEC_PATH=[GCC路径]
+```
+
+编译(Windows/Linux/Mac arm-none-eabi-gcc)
+
+```bash
+ scons -j4
+```
+
+出现下列信息即为编译成功
+
+```bash
+ LINK rtthread.elf
+ arm-none-eabi-objcopy -O binary rtthread.elf rtthread.bin
+ arm-none-eabi-size rtthread.elf
+ text data bss dec hex filename
+ 41596 356 1456 43408 a990 rtthread.elf
+ scons: done building targets.
+```
+
+
+如果编译正确无误,会产生rtthread.elf、rtthread.bin文件。其中rtthread.bin为二进制固件
+
+## 3. 烧写及执行
+
+烧写可以使用仿真器 ISP等多种方式 此处不再赘述
+
+### 3.1 运行结果
+
+如果编译 & 烧写无误,会在串口1*上看到RT-Thread的启动logo信息:
+
+```bash
+ \ | /
+- RT - Thread Operating System
+ / | \ 3.0.4 build May 15 2018
+ 2006 - 2018 Copyright by rt-thread team
+msh />
+```
+
+*默认串口
+
+
+## 4. 驱动支持情况及计划
+
+| 驱动 | 支持情况 | 备注 |
+| ---------- | :------: | :--------------------------------: |
+| UART | 支持 | UART1/4/5/7 |
+| cache | 支持 | / |
+| MPU | 支持 | SRAM cache使能权限全开 SDRAM未配置 |
+| SDRAM | 支持 | / |
+
+
+### 4.1 IO在板级支持包中的映射情况
+
+| IO号 | 板级包中的定义 |
+| -- | -- |
+| PA9 | USART1 TX |
+| PA10 | USART1 RX |
+| PA0 | UART4 TX |
+| PC11 | UART4 RX |
+| PC12 | UART5 TX |
+| PB8 | UART5 RX |
+| PA15 | UART7 TX |
+| PA8 | UART7 RX |
+
+## 5. menuconfig Bsp菜单详解
+
+| 选项 | 解释 |
+| -- | -- |
+| Using SDRAM | 使能SDRAM 若开启RT_USING_MEMHEAP_AS_HEAP 可作为heap使用 默认开启 |
+| using uart1 | 开启串口1,串口1的设备名为"uart1" |
+| using uart4 | 开启串口2,串口1的设备名为"uart4" |
+| using uart5 | 开启串口3,串口1的设备名为"uart5" |
+| using uart7 | 开启串口4,串口1的设备名为"uart7" |
