-# raspi2
-RT-Thread for Raspberry Pi 2B
+|# Raspberry A7板级支持包说明
+
+## 1. 简介
+
+树莓派由注册于英国的慈善组织“Raspberry Pi 基金会”开发，莓派2采用4核Broadcom BCM2836 (ARMv7-A)芯片、双核VideoCore IV GPU和1GB内存。
+
+这份RT-Thread BSP是针对 Raspberry Pi 2B 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。
+
+当前Raspberry Pi 2B对应的硬件特性：
+
+| 硬件   |         描述                            |
+|------- | -------------------------------         |
+|  CPU   | ARM Cortex-A7（4核心）                   |
+|  主频  | 900M                                  |
+| Memory | 1GB  (0x0000000 - 0x40000000)            |
+|	     | 其中0x3f000000 - 0x40000000为peripheral |
+
+## 2. 编译说明
+
+Windows环境下推荐使用[env工具][1]
+
+Linux下推荐使用gcc工具 [gcc-arm-none-eabi-4_8-2014q1_linux][2]，如果还没有编译工具，下载后，解开文件。
+
+```
+tar vxf gcc-arm-none-eabi-4_8-2014q1_linux.tar.bz2
+```
+
+Linux环境可能需要修改编译器目录设置，修改bsp/raspi2/rtconfig.py中的
+
+```
+EXEC_PATH   = r'/opt/gcc-arm-none-eabi-4_8-2014q1_gri/bin'
+```
+
+为编译工具的实际所在目录，这里注意要加上后缀 /bin
+
+进入到`bsp/raspi2`目录中，运行以下命令：
+
+```
+scons
+```
+
+来编译这个板级支持包。如果编译正确无误，会产生kernel.elf、kernel.img文件。
+kernel.img即是要cp到raspberry SD卡中根目录的文件
+
+
+## 3. 执行
+
+### 3.1 下载[raspbian镜像][3]，生成可以运行的raspbian SD卡
+
+Windows下，去[etcher.io][4]下载etcher,这是个可以烧写img的工具
+
+解开下载的镜像文件, linux下使用如下的命令
+
+```
+unzip 2018-06-27-raspbian-stretch-lite.zip
+```
+
+准备一张空SD卡，linux环境下，插入电脑并执行
+
+```
+sudo dd if=2018-06-27-raspbian-stretch-lite.img of=/dev/xxx bs=32M conv=fsync
+```
+
+**注意: /dev/xxx 要换成真实环境中的SD卡所在设置，千万不要弄错。**
+
+Windows环境下，执行etcher选择解压后的2018-06-27-raspbian-stretch-lite.img文件和SD卡就可以开始烧写了。
+
+最后把kernel7.img放入SD boot分区，覆盖原来的文件。
+
+### 3.2 准备好串口线
+
+目前版本是使用raspi2的 GPIO 14, GPIO 15来作路口输出。
+
+串口参数： 115200 8N1 ，硬件和软件流控为关。
+
+按上面的方法做好SD卡后，插入树莓派2B，通电。
+
+输出到串口的信息应该是这样的：
+
+```text
+ heap: 0x00020b20 - 0x00400000
+
+ \ | /
+- RT -     Thread Operating System
+ / | \     3.1.0 build Aug 23 2018

+```
