【Tiny4412】搭建Qt网络文件系统

00. 目录

01. 编译内核

1.1 解压内核源码

[root@itcast tools]# tar -xjvf linux-3.5_analyse.tar.bz2 

1.2 配置内核

[root@itcast linux-3.5_analyse]# make clean 
[root@itcast linux-3.5_analyse]# cp tiny4412_linux_defconfig  .config 
[root@itcast linux-3.5_analyse]# 

1.3 关闭TtrustZone

[root@itcast linux-3.5_analyse]# vim .config +485
注释485行
485 #CONFIG_ARM_TRUSTZONE is not set #=y

1.4 编译源码

[root@itcast linux-3.5_analyse]# make -j4

PC端输入

[root@itcast linux-3.5_analyse]# fastboot flash kernel arch/arm/boot/zImage 
sending 'kernel' (4671 KB)...
OKAY [  1.268s]
writing 'kernel'...
OKAY [  0.372s]

[root@itcast linux-3.5_analyse]# 

03. 烧写Qt根分区映像

[root@itcast Qt]# fastboot flash ramdisk ramdisk-u.img 
sending 'ramdisk' (987 KB)...
OKAY [  0.277s]
writing 'ramdisk'...
OKAY [  0.081s]

[root@itcast Qt]# 

04. 搭建Qt网络文件系统

4.1 解压qt网络文件系统

[root@itcast Qt]# pwd
/home/tools/Qt
[root@itcast Qt]# ls
ramdisk-u.img  rootfs_qtopia_qt4-20141213.tar.gz
[root@itcast Qt]# tar -xzvf rootfs_qtopia_qt4-20141213.tar.gz 

4.2 移动目录

[root@itcast Qt]# mv rootfs_qtopia_qt4  /
[root@itcast Qt]# cd /
[root@itcast /]# mv rootfs_qtopia_qt4/ qtrootfs
[root@itcast /]# ls
bin   cgroup  etc   lib    lost+found  misc  net  proc      root  selinux  sys  usr
boot  dev     home  lib64  media       mnt   opt  qtrootfs  sbin  srv      tmp  var
[root@itcast /]# 

4.3 设置nfs共享

[root@itcast /]# vim /etc/exports 
#最后添加一下内容
/qtrootfs *(rw,sync,no_root_squash)

4.4 启动nfs服务

[root@itcast /]# iptables -F 
[root@itcast /]# setenforce  0
[root@itcast /]# /etc/init.d/rpcbind restart
停止 rpcbind：                                             [确定]
正在启动 rpcbind：                                         [确定]
[root@itcast /]# /etc/init.d/nfs restart

启动 NFS 守护进程：                                        [确定]
正在启动 RPC idmapd：                                      [确定]
[root@itcast /]# 

4.5 验证共享目录

[root@itcast Android]# showmount  -e 172.16.0.53
Export list for 172.16.0.53:
/qtrootfs *

4.6 设置启动参数

DengJin #set bootargs root=/dev/nfs nfsroot=172.16.0.88:/qtrootfs 
ip=172.16.0.77  console=ttySAC0,115200 lcd=S70 ctp=2
DengJin #save

4.7 环境变量如下

DengJin # printenv
baudrate=115200
bootargs=root=/dev/nfs nfsroot=172.16.0.53:/qtrootfs ip=172.16.0.251 
console=ttySAC0,115200 lcd=S70 ctp=2
bootcmd=movi read kernel 0 40008000;bootm 40008000
bootdelay=3
