系统烧写总是不成功
是不是我的板子或者板载eMMC有问题
按照手册[E9_天嵌科技出品- 开发板使用手册_20131115.pdf]的说明
在winxp下用mfgtool烧写Ubuntu,烧写过程虽然正常结束，
切换回eMMC启动模式后，串口报：
*** Warning - bad CRC or MMC, using default environment
##### EmbedSky BIOS for E9 #####
Hit any key to stop autoboot: 3
booti: bad boot image magic
fastboot is in init......flash target is MMC:3
Bad partition index:2 for partition:recovery
Bad partition index:5 for partition:system
wait usb cable into the connector!
用随机光盘提供的uboot.bin,uImage,oneiric.zip从SD烧写时，
串口经常没有输出，要不就是像[？口]的非常短的乱麻，
就像没法加电一样
偶尔在长时间没反应时拔掉电源再立刻插上后，串口会有如下输出，然后就停止了
