TI中文支持网版主您好！
我使用的内核和文件系统分别是：uImage_ipnc_dm368_2.6.0和cramfsImage_ipnc_dm368_2.6.0
启动中报错：
……
VFS: Mounted root (cramfs filesystem) readonly.
Freeing init memory: 180K
Error -3 while decompressing!
c03c211f(2652)->c0669000(4096)
请问是什么原因？文件系统跟内核都用的是开发包中原始自带的
Louis：
你好，
请问你用的是什么板子？TI的开发板么？

回复 Louis:
是这样的，我们以前是参考TI的DVSDK设计的，
目前我们想转到IPNC的环境上来，我用的UBL跟UBOOT都是dvsdk的
内核跟文件系统用的IPNC的；启动的时候，内核都启动完了，在解压文件系统的时候就卡在那儿了
板子是我们自己的板子，用DVSDK那一套东西是跑通了的

学会看log
IP-Config: No network devices available.
说明你没有把以太网驱动编译进来，看IPNC user guide，要用NFS的kernel配置
另外一个，你的IPNC软件太老，请联系TI代理商，获取新版本IPNC v3.1或者IPNC v4.1

内核用的是开发包中编译好的uImage
IPNC的同样提示：IP-Config: No network devices available.

你的理解是对的
去把以太网驱动编译进内核吧，你用的IPNC版本应该是2.6的，2.6版本的以太网驱动是放在文件系统里加载的
3.x以后的已经改过来了

兄弟，解决问题了吗？
个人认为很可能是 cramfs 镜像包 完整性问题。 可能是你 tftp 或 write to nand 时没有把镜像完全下载或写入，或者linux启动参数中指定的解压目的内存空间不够。总之，就是cramfs解压过程出错了，仔细检查下
