 ## 2. 编译说明
 
-Linux下推荐使用[gcc工具][2]。Linux版本下gcc版本可采用`gcc-arm-8.3-2019.03-x86_64-aarch64-elf`。
-
-将工具链解压到指定目录,并修改当前bsp下的`EXEC_PATH`为自定义gcc目录。
+推荐使用[env工具](https://www.rt-thread.org/page/download.html)，可以在console下进入到`bsp\raspberry-pi\raspi4-32`目录中，运行以下命令：

+# Raspberry PI 4板级支持包说明
+
+## 1. 简介
+
+树莓派4B的核心处理器为博通BCM2711（四核1.5GHz，Cortex A72架构，树莓派3是四核A53）。LPDDR4内存，由5V/3A USB-C供电或GPIO 5V。
+
+外设支持上，引入了双频Wi-Fi，蓝牙5.0，千兆网卡，MIPI CSI相机接口，两个USB口，40个扩展帧。
+
+这份RT-Thread BSP是针对 Raspberry Pi 4的一份移植，树莓派价格便宜, 使用者甚众，是研究和运行RT-Thread的可选平台之一。
+
+
+## 2. 编译说明
+
+
+
+### 2.1 Window上的环境搭建
+
+Windows环境下推荐使用[env工具](https://www.rt-thread.org/page/download.html)进行编译。
+
+首先下载windows上的aarch64的gcc交叉编译工具，版本为gcc-arm-8.3选择aarch64-elf就可以。
+
+将推荐将gcc解压到`\env\tools\gnu_gcc\arm_gcc`目录下。
+
+接着修改`bsp\raspberry-pi\raspi4-64\rtconfig.py`
+
+修改路径：
+
+```
+EXEC_PATH = r'E:/env_released_1.1.2/env/tools/gnu_gcc/arm_gcc/gcc-arm-8.3-2019.03-i686-mingw32-aarch64-elf/bin'
+```
+
+然后在`bsp\raspberry-pi\raspi4-64\`下输入scons编译即可。
+
+**window环境搭建注意**
+
+下载完成`gcc-arm-8.3-2019.03-i686-mingw32-aarch64-elf.tar.xz`交叉编译工具链后，最好采用7-zip解压工具进行两次解压。
+确保解压目录下的`/bin/aarch64-elf-ld.exe`文件的size不为0。
+否则编译会出现如下错误:
+
+```
+collect2.exe:fatal error:CreateProcess:No such file or directory
+```
+
+### 2.2 Linux上的环境搭建
+
+Linux下推荐使用[gcc工具][2]。Linux版本下gcc版本可采用`gcc-arm-8.3-2019.03-x86_64-aarch64-elf`。
+
+将工具链解压到指定目录,并修改当前bsp下的`EXEC_PATH`为自定义gcc目录。
+
+```
+PLATFORM    = 'gcc'
+EXEC_PATH   = r'/opt/gcc-arm-8.3-2019.03-x86_64-aarch64-elf/bin/'  
+```
+
+直接进入`bsp\raspberry-pi\raspi4-64`，输入scons编译即可。
+
+
+## 3. 执行
+
+### 3.1 下载**Raspberry Pi Imager**，生成可以运行的raspbian SD卡
+
+首先下载镜像
+
+* [Raspberry Pi Imager for Ubuntu](https://downloads.raspberrypi.org/imager/imager_amd64.deb)
+* [Raspberry Pi Imager for Windows](https://downloads.raspberrypi.org/imager/imager.exe)
+* [Raspberry Pi Imager for macOS](https://downloads.raspberrypi.org/imager/imager.dmg)
+
+### 3.2 准备好串口线
+
+目前版本是使用raspi4的 GPIO 14, GPIO 15来作路口输出，连线情况如下图所示：
+
+![raspi2](../raspi3-32/figures/raspberrypi-console.png)
+
+串口参数： 115200 8N1 ，硬件和软件流控为关。
+
+### 3.3 程序下载
+
+当编译生成了rtthread.bin文件后，我们可以将该文件放到sd卡上，并修改sd卡中的`config.txt`文件如下：
+
+```
+enable_uart=1
+arm_64bit=1
+kernel=rtthread.bin
+```
+
+按上面的方法做好SD卡后，插入树莓派4，通电可以在串口上看到如下所示的输出信息：
+
+```text
