烧录android镜像文件后反复进入U-BOOT读秒
请教,我的板子突然出现上电后反复进入U-BOOT读秒,无法正常启动Android.
重新烧录你们提供的android image也不行。
是不是板子出问题了?
谢谢

一.检查一下你的启动方式对不对,用尖头的物体,拨动拨码开关,看看拨到位没有
二.有没有烧写过Uboot,如果烧写过,可能是烧写的uboot和Linux内核以及Android文件不对应,你烧写同一个文件夹中烧写文件试试的试试
大部分情况,都是上面2个原因 |

1)拨码开关没动过;
2)重新烧录你们提供的所有镜像文件,包括u-boot,内核,ramdisk,system; 也不行;
3)很奇怪的是,前一次还可以;但是断电后重新上电后就再也无法正常启动了; |

用什么方式烧录的?在烧录前,串口显示uboot数秒时,按任意按键进入uboot命令行,在串口执行下面的命令(分区格式化EMMC)
fdisk -c 0
fatformat mmc 0:1
ext3format mmc 0:2
ext3format mmc 0:3
ext3format mmc 0:4
然后再烧写下光盘里提供的Android的四个镜像文件 |
