RaspberryPi树莓派无法启动了排查过程

最近没用树莓派突然无法启动了RaspberryPi树莓派无法启动了排查过程 记录如下

  1. 首先确认是否电源供电问题现在的现象是电源灯PWR常亮电源用的是iPad的用表接伴奏上的TP1和TP2测了下电压5.05V看起来电源正常参考资料为提示树莓派90%的故障是电源故障!!附5V电源检查方法
  2. 又仔细看了下官方的wiki发现以下一句If the card is not new, you should format it and make sure there is only one partition (FAT32 is a good choice); otherwise Win32DiskImager can make corrupt your SD card!” 猜想可能是没写好SD卡此时把SD卡插到本本的SD卡槽无反应于是用了个读卡器这次可以看到SD卡大小为250M在window磁盘管理里面看到确实有隐藏的分区在SD卡上于是乎找了恢复工具SD卡擦空还原(恢复原始容量)新工具SD Formatter恢复后卡容量显示正确winimagewriter重新烧录2013-02-09-wheezy-raspbian.img未果又用flashnul烧了一下还是只拷贝了60M左右应该看起来明显不对
  3. 于是换一张新卡这次拷贝貌似正确希望这次好用。。。。。。。。。。D:\InstFiles\ISO\Tools\flashnul-1rc1>flashnul.exe I: -L D:/InstFiles/ISO/RPi/Raspbian/2013-02-09-wheezy-raspbian.img

    THIS OPERATION IS DESTRUCTIVE!!!
    Type ‘yes’ to confirm operation. All other text will stop it.

    Really destroy data on drive I:? :yes

    Press ENTER to exit.

  4. 但是上一步的貌似正确的卡还是无法启动。要放弃了的时候又重新拿新卡重复了一遍SDFormater和winimagewriter. 这次尽然启动了…
