# Raspberry PI 3B(32位)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3采用4核Broadcom BCM2837 (ARMv8)芯片、双核VideoCore IV GPU和1GB内存。
|
||||
|
||||
这份RT-Thread BSP是针对 Raspberry Pi 3B （32位）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。
|
||||
|
||||
随着RT-Thread的发展，它越来越多的向一些Cortex-A等AP类处理器提供支持，例如全志的ARM9、Cortex-A处理器，Xilinx的Zynq处理器等。
|
||||
|
||||
而RT-Thread也是一套高度社区化发展的操作系统，所以在一些方向推进上希望以社区化方式，大家一起来推动的方式向前发展，在这个过程中RT-Thread得到了不同开发者、不同领域的应用，一步步把RT-Thread推向成熟。而在Cortex-A平台上，目前最流行的硬件平台是树莓派，分树莓派[2B](https://www.raspberrypi.org/products/raspberry-pi-2-model-b/)、[3B](https://www.raspberrypi.org/products/raspberry-pi-3-model-b/)以及最新的[4B](https://www.raspberrypi.org/products/raspberry-pi-4-model-b/)等。
|
||||
|
||||
RT-Thread对树莓派的支持主要从树莓派2B开始，它是一个四核Cortex-A7的平台，以32位单核的模式运行。后续将推动着RT-Thread向树莓派3，四核Cortex-A53 64位模式发展（中间当然也可能出现四核Cortex-A7模式执行的过渡性版本）。
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
当前Raspberry Pi 3B对应的硬件特性：
|
||||
|
||||
| 硬件 | 描述 |
|
||||
|------- | ------------------------------- |
|
||||
| CPU | quad-core ARM Cortex A53(ARMv8) |
|
||||
| 主频 | 1.2 GHz |
|
||||
| GPU | VideoCore IV |
|
||||
| GPU频率 | 400MHz |
|
||||
| Memory | 1GB (0x0000000 - 0x40000000) |
|
||||
| | 其中0x3f000000 - 0x40000000为peripheral |
|
||||
|
||||
硬件引脚分布情况
|
||||
|
||||
|
||||
|
||||
## 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/raspi3-32/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/raspi3-32`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rtthread.elf、kernel7.img文件。
|
||||
kernel7.img即是要cp到raspberry SD卡中根目录的文件
|
||||
|
||||
### 2.1 eclipse 编码环境 ###
|
||||
第一步： 安装 eclipse cdt
|
||||
第二步： 打开 eclipse cdt 设置workspace ,推荐设置于xxx\xxx\rt-thread\bsp
|
||||
第三步： Import 工程 General-> Existing Peojects into Workspace 然后 Browse.. 你的raspi3目录，点击Finish
|
||||
|
||||
btw:编译依旧使用scons,目前不支持qemu debug,后期如果有大佬实现ARM JTAG调试
|
||||
|
||||
## 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raspi3的 GPIO 14, GPIO 15来作路口输出，连线情况如下图所示：
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
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3B，通电可以在串口上看到如下所示的输出信息：
|
||||
|
||||
```text
|
||||
heap: 0x0005d784 - 0x0045d784

# Raspberry PI 3-64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3有三个发行版本：
|
||||
|
||||
* B : 4核 Broadcom BCM2837 (ARMv8-A) 1.2GHz，双核VideoCore IV GPU，1GB内存，100 Base-T Ethernet
|
||||
* B+: 4核 Broadcom BCM2837B0 Cortex-A53 (ARMv8) 1.4GHz, 1GB LPDDR2 SDRAM， GigaE over USB 2.0
|
||||
* A+: 4核 Broadcom BCM2837B0 Cortex-A53 (ARMv8) 1.4GHz, 512MB LPDDR2 SDRAM
|
||||
|
||||
这份RT-Thread BSP是针对 Raspberry Pi 3 64位模式的一份移植，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][1]进行编译。
|
||||
|
||||
首先下载Linux上的gcc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\raspi3-64\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\raspi3-64\`下输入scons编译即可。
|
||||
|
||||
### 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`。
|
||||
|
||||
直接进入`bsp\raspberry-pi\raspi3-64`，输入scons编译即可。
|
||||
|
||||
|
||||
## 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kernel8.img放入SD boot分区，删除其它 kernel*.img。
|
||||
|
||||
### 3.2 准备好串口线
|
||||
|
||||
目前版本是使用raspi3的 GPIO 14, GPIO 15来作路口输出，连线情况如下图所示(图片中的板子是pi2，GPIO引脚是一样的)：
|
||||
|
||||
|
||||
|
||||
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，通电可以在串口上看到如下所示的输出信息：
|
||||
|
||||
```text

||||
