01. 編譯內核

1.1 解壓內核源碼

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

1.2 配置內核

[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 關閉TtrustZone

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

1.4 編譯源碼

[root@itcast linux-3.5_analyse]# make -j4 .....CC crypto/ansi_cprng.mod.oCC drivers/char/tiny4412_hello_module.mod.oCC drivers/scsi/scsi_wait_scan.mod.oOBJCOPY arch/arm/boot/ImageLD [M] crypto/ansi_cprng.koLD [M] drivers/scsi/scsi_wait_scan.koLD [M] drivers/char/tiny4412_hello_module.koKernel: arch/arm/boot/Image is readyAS arch/arm/boot/compressed/head.oGZIP arch/arm/boot/compressed/piggy.gzipCC arch/arm/boot/compressed/misc.oCC arch/arm/boot/compressed/decompress.oCC arch/arm/boot/compressed/string.oSHIPPED arch/arm/boot/compressed/lib1funcs.SSHIPPED arch/arm/boot/compressed/ashldi3.SAS arch/arm/boot/compressed/lib1funcs.oAS arch/arm/boot/compressed/ashldi3.oAS arch/arm/boot/compressed/piggy.gzip.oLD arch/arm/boot/compressed/vmlinuxOBJCOPY arch/arm/boot/zImageKernel: arch/arm/boot/zImage is ready

PC端輸入

[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] finished. total time: 1.641s [root@itcast linux-3.5_analyse]#

03. 燒寫Qt根分區映像

[root@itcast Qt]# fastboot flash ramdisk ramdisk-u.img sending 'ramdisk' (987 KB)... OKAY [ 0.277s] writing 'ramdisk'... OKAY [ 0.081s] finished. total time: 0.358s [root@itcast Qt]#

04. 搭建Qt網絡文件系統

4.1 解壓qt網絡文件系統

[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 移動目錄

[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 設置nfs共享

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

4.4 啟動nfs服務

[root@itcast /]# iptables -F [root@itcast /]# setenforce 0 [root@itcast /]# /etc/init.d/rpcbind restart 停止 rpcbind： [確定] 正在啟動 rpcbind： [確定] [root@itcast /]# /etc/init.d/nfs restart 關閉 NFS 守護進程： [失敗] 關閉 NFS mountd： [失敗] 關閉 NFS quotas： [失敗] Shutting down RPC idmapd: [失敗] 啟動 NFS 服務： [確定] 關掉 NFS 配額： [確定] 啟動 NFS mountd： [確定] 啟動 NFS 守護進程： [確定] 正在啟動 RPC idmapd： [確定] [root@itcast /]#

4.5 驗證共享目錄

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

4.6 設置啟動參數

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 環境變量如下

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 ethaddr=00:40:5c:26:0a:5b gatewayip=192.168.0.1 ipaddr=192.168.0.20 netmask=255.255.255.0 serverip=192.168.0.10Environment size: 691/16380 bytes DengJin #

4.8 Qt界面顯示如下
成功啟動Qt文件系統的界面如下：
