-### 3.2 准备好串口线
+### 3.2 RTT固件放在SD卡运行
 
-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：
+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。

-串口参数： 115200 8N1 ，硬件和软件流控为关。
+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
 
-### 3.3 程序下载
+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。
 
-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：
+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：
 
 ```
-enable_uart=1
-arm_64bit=0
-kernel_addr=0x8000
-kernel=kernel7.img
-core_freq=250
+setenv bootcmd "dhcp 0x00200000 x.x.x.x:kernel7.img;dcache flush;go 0x00200000"
+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: 0x00044270 - 0x04044270
+**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`。
+
+```
+SECTIONS
+{
+    . = 0x8000;
+    . = ALIGN(4096);
+    .
+    .
+    .
+}
+```
+
+改为
+
+```
+SECTIONS
+{
+    . = 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。
