是/sbin/reboot的问题？还是文件系统的问题？没人关心？！

testh · 发表于 2010-9-15 12:11:02

你的系统版本是多少？
我的TQ2440-2.6.30.4的运行reboot没有问题呀

自带的2.6.30.4内核 + root_qtopia_2.2.0_2.6.30.4_256MB.bin文件系统。

先后共买过4块板，均有上述问题，故大致可推断非硬件问题。

没有啊，连norflash的uboot都没有改动过。

你贴的图片怎么看不清楚。
我想看看启动结束和reboot开始的那段

可以的，单击下图片，然后点右上角的中间的“实际大小”，如图：

另外，赞一下，你们这个网页做得很不错。自己写的？

天嵌_support1 · 发表于 2010-9-15 16:58:56

进入uboot命令，选择 0 命令，输入 2，再输入 s ,然后从Nand启动再试一试

effendi · 发表于 2010-9-15 17:03:23

这样？？？

很遗憾，reboot后仍然会这样。
