 以上三步完成之后，重启系统，就可以省略每次都需要进入pmon的输入命令的麻烦，板子上电后，可以自动从系统TFTP服务器中获取固件，然后启动，大大提高调试代码效率。
 
-## 5. 支持情况
+## 5.SATA接口的SSD文件系统支持
+
+当前已经支持SATA接口的SSD文件系统驱动，需要通过menuconfig
+
+```
+RT-Thread online packages  --->
+	 			system packages  --->
+	 				lwext4: an excellent choice of ext2/3/4 filesystem for microcontrollers
+```
+
+然后输入下面的命令更新软件包
+
+```
+pkgs --update
+```
+
+输入`scons`编译代码即可使用SATA接口的SSD文件系统。
