这家伙很懒，什么也没写！

K9ii开发板用的bootloader是u-boot，采用如下方式下载RT-Thread RTOS：
```
tftpboot 0x20008000 rtthread-AT9200.bin
```
（需要在PC上启动个tftp server）
把`rtthread-AT9200.bin`文件下载到板子上的0x20008000的位置，`rtthread-AT9200.bin`是RT-Thread的二进制文件，在`bsp\AT9200`目录下

```
go 0x20008000
```
从0x20008000位置开始运行

整个开始运行画面：
```
Enter k9-Uboot
