使用的外围器件:宇瞻8G class10 SD卡,5V1A和5V2A电源,Dell USB接口键盘,HDMI转DVI线,19寸液晶显示器
镜像文件:树莓官方网站下载,直接下载和BT下载都试了。(下载下来的文件使用官网上的校验方式得到的校验码和官网的不一致,但是官网的校验码有两个,还不一样)
失败现象:上电后PWR灯常亮,ACT灯闪烁或熄灭,显示器上能看到树莓的图标(logo),有时候还能看到光标闪烁一两次后就不闪了。感觉像是运行到某处后死机
已经尝试的处理方式:
1.重新制作镜像。- Raspbian “wheezy”
- If you’re just starting out, this is the image we recommend you use. It’s a reference root filesystem from Alex and Dom, based on the Raspbian optimised version of Debian, and containing LXDE, Midori, development tools and example source code for multimedia functions.Torrent 2012-10-28-wheezy-raspbian.zip.torrent
- Direct download 2012-10-28-wheezy-raspbian.zip
- SHA-1 3ee33a94079de631dee606aebd655664035756be

插上键盘上电、不插键盘上电,结果都一样。
3.怀疑电源问题
一开始使用5V1A中兴手机充电器,后来使用友善之臂ARM开发板配套的5V2A电源,都是一样。
4.怀疑SD卡问题
打算今天换个SD卡试试看,手头没有SD卡,打算用2GTF卡加SD卡套(不知道容量够不够。)
请大家指点下,是哪里的问题
谢谢! |
