AT91SAM9263EK之串口下载Linux内核至SDRAM

建立终端连接

XP的超级终端—–>选择串口——>数据流控制（选择xon/xoff或者无否则在终端中不能输入指令）

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

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
