### 4.1 使用VSCode编辑、编译、调试
在qemu-vexpress-a9中已经携带了部分vscode的配置需要配合着env一起来使用。步骤包括
先使用env打开console然后在console中切换都qemu-vexpress-a9 bsp的目录下
```bash
scons --target=vsc -s
```
更新vscode需要用到的C/C++头文件搜索路径信息不是每次都需要更新只有在使用了menuconfig重新配置了RT-Thread或更改了rtconfig.h头文件时才需要
然后在console下输入
```bash
code .
```
启动vscode。使用vscode目前包含如下的一些功能
* 编译 `Ctrl+Shift+B` - 开启vscode内置终端调用scons进行编译如果有编译错误也会侦测问题双击问题跳到指定代码文件、代码行
* 包含执行`qemu`模拟器,`scons -c`进行目标文件清理的任务
* `F5` 一键开启QEMU调试模式并断点停留在`main`函数上;(需要更改下qemu-dbg.bat文件在qemu-system-arm前加入`start`),即
```batch
@echo off
if exist sd.bin goto run
qemu-img create -f raw sd.bin 64M
:run
start qemu-system-arm -M vexpress-a9 -kernel rtthread.elf -serial stdio -sd sd.bin -S -s
```
**已知问题** 如果在vscode的目录中额外添加了文件夹会导致调试不能够启动。

# Raspberry PI 2B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。
![raspi2](figures/raspi2.png)
当前Raspberry Pi 2B对应的硬件特性
| 硬件 | 描述 |
|------- | ------------------------------- |
| CPU | ARM Cortex-A74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]进行编译。
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环境下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`rt-thread/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来作路口输出连线情况如下图所示
![raspi2](figures/raspi_uart.png)
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通电可以在串口上看到如下所示的输出信息
```text
