GEC210系统烧写过程记录（fastboot方式）
Windows下USB系统烧写
准备材料：
1、系统镜像——包括u-boot.bin、uImage-7Inch、rootfs-qtopia-finish.img
2、fastboot工具——包括fastboot.exe、adb.exe、AdbWinApi.dll、AdbWinUsbApi.dll
注意：将fastboot.exe、adb.exe、AdbWinApi.dll、AdbWinUsbApi.dll四个文件复制到C:\WINDOWS\system32目录下，运行中输入cmd进入命令行模式，输入fastboot 测试，如果出现“usage: fastboot [
步骤一：
【开发板端】开发板连接SecureCRT终端，进入bootloader模式，输入命令fastboot。（如果是第一次连接，可能会提示安装驱动，可以手动选择目录gec210_android_driver安装，或者自动安装。）
SecureCRT打印的信息——

步骤二：
【PC端】运行“cmd”进入命令行模式，切换到u-boot.bin所在目录，输入 fastboot flash uboot u-boot.bin
如果烧写成功，会出现 sending 'uboot' <432 KB> ... OKAY, writing 'uboot' ... OKAY
