## 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：
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\raspi4-64`目录中，运行以下命令：
```
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'
scons
```
然后在`bsp\raspberry-pi\raspi4-64\`下输入scons编译即可。
来编译这个板级支持包。如果编译正确无误，会产生 `rtthread.elf`, `rtthread.bin` 文件。
**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
## 3. 环境搭建
### 3.1 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：
@ -73,27 +28,61 @@ EXEC_PATH = r'/opt/gcc-arm-8.3-2019.03-x86_64-aarch64-elf/bin/'
串口参数： 115200 8N1 ，硬件和软件流控为关。
### 3.3 程序下载
### 3.2 RTT固件放在SD卡运行
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：
暂时不支持，需要使用 u-boot 加载。
### 3.3 RTT程序用uboot加载
此 bsp 的 `tools` 下可以找到 [u-boot64.bin](./tools/u-boot64.bin) 和 [config.txt](./tools/config.txt) 两个文件。将其与准备好的 sd 卡中文件替换即可。sd 卡推荐通过树莓派 [imager](https://www.raspberrypi.com/software/) 制作。
需要注意的以下步骤：
**1.电脑上启动tftp服务器**
windows系统电脑上可以安装tftpd搭建tftp服务器。将目录指定到`bsp\raspberry-pi\raspi4-64`。
**2.修改设置uboot**
在控制台输入下列命令：
```
enable_uart=1
arm_64bit=1
kernel=rtthread.bin
core_freq=250
setenv bootcmd "dhcp 0x00208000 x.x.x.x:rtthread.bin;dcache flush;go 0x00208000"
saveenv
reset
```
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：
其中`x.x.x.x`为tftp服务器的pc的ip地址。
```text
heap: 0x000c9350 - 0x040c9350
**3.修改链接脚本**
链接脚本会在 python 脚本中自行替换，不用处理
**3.插入网线**
上述准备完成后，将网线插入，保证开发板和tftp服务器在同一个网段的路由器上。上电后uboot可以自动从tftp服务器上获取固件，然后开始执行了。
完成后可以看到串口的输出信息
```

## 5. 联系人信息
## 5. 注意事项
目前rt-thread程序可以使用的内存在100MB以内，可以通过调整`board.c`中`platform_mem_desc`表的数据进行相关内存的映射以及修改`board.h`来确定程序使用的堆栈大小。
