DM368 MT5 IPNC 3.0 SDK的问题？

mount不了根文件系统，把bootargs后面quiet去掉，把log贴出来看看

这是bootargs后面quiet去掉后，在超级终端里显示的启动信息。

照着IPNC 3.0 SDK里的文档都整出来有问题，真是晕死呀！ 不会是Appro 这个版本的SDK本身还有Bugs就 Release出来了吧？！

嗯，谢谢专家啊！

我之前看错误提示信息，也怀疑过是flash太小了的原因，但一直无法确认这个问题。所以，我不是还发了另外一个帖子，咨询有关DM368上支持三星K9F1G08U0C-PCB0 128MB nand flash的事情吗？目前还在做 SD Boot 呢，还没搞定。。。哎！老板每天都盯得紧，没办法呀！问题不搞定，国庆都还得加班呢。。

因为我们现在还是用的K9F5608U0C 32MB nand flash，之前是跑的Appro 2.6 SDK，软件都可以正常运行，看得到视频；没想到升级到 3.0 SDK后，系统都跑不起来了，所以一开始确实也没往这个 flash 大小的问题去想。。

请问ipnc 3.0 如何获取？？？
