DM368 MT5 IPNC 3.0 SDK的问题？

Jessie Pan

之前使用的是Appro 2.6 SDK，烧录SDK里自带ubl，u-boot，kernel，file system，软件都可以正常跑起来，也可以通过VLC和在IE里看到视频图像。现将SDK版本升级到Version 3.0，参照IPNC文档，烧录了SDK里的ubl，u-boot，uImage_ipnc_dm368_3.0.0和ipnc_dm368_3.0.0.squashfs，并且在u-boot下设置了参数，如下：

tftpboot 0x80700000 uImage_ipnc_dm368_3.0.0;tftpboot 0x82000000 ipnc_dm368_3.0.0.squashfs
nand erase 0x500000 0x400000;nand write 0x80700000 0x500000 0x400000
nand erase 0x900000 0x1000000;nand write 0x82000000 0x900000 0x1000000
setenv bootcmd 'nboot 0x80700000 0 0x500000;bootm 0x80700000'
setenv bootargs 'mem=48M console=ttyS0,115200n8 root=/dev/mtdblock3 rootfstype=squashfs ip=192.168.1.168:192.168.1.100:192.168.1.1:255.255.255.0:::off eth=00:0C:0C:02:37:A6 lpj=1077248 cmemk.phys_start="0x83000000" cmemk.phys_end="0x88000000" cmemk.phys_start_1="0x00001000" cmemk.phys_end_1="0x00008000" cmemk.pools_1="1x28672" cmemk.allowOverlap="1" quiet';setenv verify no;saveenv;reset

系统无法启动，超级终端下的提示信息如下：

是我的操作哪里出了问题吗？

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？！

遇到问题不要慌！搞清楚问题先！心浮气躁怎么搞技术！！！

你这个flash是32M的吧，DM368缺省的配置是128MB，这样MTD表超过了大小限制了

修改内核MTD表，你可以用DM365 IPNC的MTD表做参考！

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。。
