4.2. 编译

刚才配置好了，这里编译只需make一下就可以了 [root@localhost 1b-linux-3.0-d8b47bb]# make

然后，慢慢等，直到编译完成。 LD .tmp_vmlinux2 KSYM .tmp_kallsyms2.S AS .tmp_kallsyms2.o LD vmlinux

SYSMAP System.map

SYSMAP .tmp_System.map

CC arch/mips/boot/compressed/dummy.o OBJCOPY arch/mips/boot/compressed/vmlinux.bin GZIP arch/mips/boot/compressed/vmlinux.bin.z OBJCOPY arch/mips/boot/compressed/piggy.o LD vmlinuz STRIP vmlinuz

[root@localhost 1b-linux-3.0-d8b47bb]# ls -l vmlinu* -rwxr-xr-x 1 root root 8520259 08-29 14:07 vmlinux -rw-r--r-- 1 root root 10324555 08-29 14:07 vmlinux.o -rwxr-xr-x 1 root root 3419144 08-29 14:07 vmlinuz [root@localhost 1b-linux-3.0-d8b47bb]#

这时候，编译完成了。

5. 启动运行linux

5.1. 拷贝vmlinux到tftp服务器目录下

我这里tftp服务之前配好的，直接用了。

[root@localhost 1b-linux-3.0-d8b47bb]# cp vmlinux /tftpboot/

5.2. 设置PMON的ip地址

给开发板通电，按空格键进入PMON。
