因为在做mkimage的时候所给参数为mkimage -A ARM -O Linux -C none -a 22200000 -e 22200040 -n uImage -d zImage uImage 所以本文用串口下载时执行命令：
U-Boot> loadb 0x22200000
U-Boot> loadb 0x22200000
U-Boot> loadb 0x22200000
发送内核
目标板准备接受内核，需要利用终端发送uImage到板子上，选择Kermit协议，完成后点击发送。发送比较慢，耐心等待。。。。。
传输完成后，终端显示如下图所示：
启动内核
U-Boot>bootm 22200000
U-Boot>bootm 22200000
U-Boot>bootm 22200000
