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。
|
||||
|
||||
|
||||
## 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：

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：
|
||||
首先需要准备一张空的32GB以下的SD卡，如果不想自己制作启动固件，可以直接从百度网盘上下载boot的固件。
|
||||
|
||||
```
|
||||
enable_uart=1
|
||||
arm_64bit=0
|
||||
kernel_addr=0x8000
|
||||
kernel=kernel7.img
|
||||
core_freq=250
|
||||
链接：https://pan.baidu.com/s/1PxgvXAChUIOgueNXhgMs8w
|
||||
提取码：pioj
|
||||
```
|
||||
|
||||
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：
|
||||
解压后将sd目录下的文件拷贝到sd卡即可。以后每次编译后，将生成的kernel7.img进行替换即可。上电后可以看到程序正常运行。

|
||||
### 3.3 RTT程序用uboot加载
|
||||
|
||||
为了调试方便，已经将uboot引导程序放入uboot目录下，直接将这些文件放到sd卡中即可。
|
||||
|
||||
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\raspi4-32`。
|
||||
|
||||
**2.修改设置uboot**
|
||||
|
||||
在控制台输入下列命令：
|
||||
|
||||
```
|
||||
setenv bootcmd "dhcp 0x00200000 x.x.x.x:kernel7.img;dcache flush;go 0x00200000"
|
||||
saveenv
|
||||
reset
|
||||
```
|
||||
|
||||
其中`x.x.x.x`为tftp服务器的pc的ip地址。
|
||||
|
||||
**3.修改链接脚本**
|
||||
|
||||
将树莓派`bsp\raspberry-pi\raspi4-32\link.ld`的文件链接地址改为`0x200000`。
|
||||
|
||||
```

||||

||||

||||

||||

|
||||

|
||||

||||

|
||||

||||

|

||||

|
||||
. = ALIGN(4096);
|
||||
.
|
||||
.
|
||||
.
|
||||
}
|
||||
```
|
||||
|
||||
重新编译程序：
|
||||
|
||||
```
|
||||
scons -c
|
||||
scons
|
||||
```
|
||||
|
||||
**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. 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。目前在地址`0x08000000`处的1M空间被映射成非cache区供树莓派4的CPU与GPU通信的消息管道。若需要扩大系统内存使用，可自行修改代码进行调整。
