Linux精简版配置及编译运行

一．内核配置linux-2.6.26.5

System Type

Support ARM920T processor

Support thumb user binaries

User space binary formats

Kernel support for ELF binaries ---------------------------------------------（1）

Networking support

Networking options-----

TCP/IP networking

IP: kernel level autoconfiguration(不需要选择dhcp rarp bootp) ----（2）

Device drivers

Network device support

Ethernet(10M or 100Mbit)

CS8900a support

File system

Network file systems

NFS file system support --------------（3）

Root file system on NFS (此处依赖2和3)

参考：config ROOT_NFS

bool "Root file system on NFS"

depends on NFS_FS=y && IP_PNP

其余的不选择或者用默认的配置。

如果（1）不选择会产生错误如下（好像根文件系统错误也会产生该问题）：

Failed to execute /linuxrc. Attempting defaults...

Kernel panic - not syncing: No init found. Try passing init= option to kernel.
