iMX53 QSB板支持三种下载镜像的方式
1> MFG tool
2> dd command 3> fastboot command
4> cfimager command
1......fastboot烧写
来至site:http://blog.csdn.net/yihui8/article/details/6613519
首先进入uboot命令行
setenv fastboot_dev mmc0
fas
然后在dos
按照需要烧写：
fastboot flash bootloader u-boot-no-padding.bin
fastboot flash uramdisk uramdisk.img
fastboot flash userdata userdata.img
fastboot flash kernel uImage
fastboot flash system system.img
烧完后重启
fastboot reboot 用 fastboot 恢复已备份的系统
在 cmd 中输入下面的命令： - fastboot erase boot
- fastboot erase recovery
- fastboot flash system system.img
- fastboot flash boot boot.img
- fastboot flash userdata data.img
- fastboot flash recovery recovery.img
- fastboot reboot
setenv bootargs_android 'console=ttymxc0 video=mxcdi0fb:RGB24,720P60 video=mxcdi1fb:RGB565,1024x768M@55 di1_primary gpu_memory=32M ip=off root=/dev/nfs init=/init nfsroot=192.168.0.10:/nfs/rootfs ip=192.168.0.100::::usb0 androidboot.console=ttymxc0 '
git 常用命令
./repo init -u git://192.168.1.25/platform/manifest.git -b r10.2_t4 //初始化
git reset --hard ORIG_HEAD //回退到原始版本
git pull //从服务器更新代码到本地
一、打tag的命令是先hard reset到自己模块(包含自己和组员)最后一次提交的位置，然后git tag tagname。Tagname的取法要统一，小项目名+完成阶段+日期。比如bsp完成了第二阶段的目标（7月6号的阶段目标），就可以命令tag为bsp-phase2-20110630
如果碰到没有全部完成，但是需要进release测试的，就把tag冠名ongoing, 如bsp-ongoing-20110630
如果碰到完成了某个bugfix，就 把BUG Number包含进去，如bsp-PRxxx-20110630 (PR指ProblemResolve,xxx指bug在JIRA系统里的编号)
二、上传tag的命令是git push review --tags
一、tag的命名加一个“工程名”的字段即 “工程名-小项目名-完成阶段-日期”;这样曾良均做整合版本的时候就知道android下有哪些工程有了需要包含的修改；
二、打tag可以指定位置，命令格式为git tag tagname commit，如git tag kernel_imx-pwrsave-phase2-20110631 cd8c0beb9ecec5e68c0535a416aea972d5f67251
三、上传某个特定tag的命令是git push review tagname.这样可以避免把本地自己命名的tag误传到服务器。

不同3G模块移植
【1】
打开：out\target\product\imx51_bbg\root\init.rc
根据不同模块修改：
#ZTE C100, add by hui
service ril-daemon /system/bin/rild -l /system/lib/libreference-ril.so -- -d /dev/ttyUSB0 -u /dev/ttyUSB2
#WCDMA U6300V, add by hui
#service ril-daemon /system/bin/rild -l /system/lib/libreference-ril.so -- -d /dev/ttyUSB1 -u /dev/ttyUSB2
【2】
打开：out\target\product\imx51_bbg\system\etc\init.gprs-pppd
根据不同模块修改：
#below is config for U6300 WCDMA modem
/system/bin/pppd /dev/ttyUSB2 9600 mru 1280 mtu 1280 nodetach debug dump defaultroute usepeerdns novj novjccomp noipdefault ipcp-accept-local ipcp-accept-remote connect-delay 5000 linkname ppp0
#below is config for ZTE CDMA modem

在我们的工作经常要验证不同相同源码不同配置内核版本，比如imx51_evk,imx53_smd,imx53_t4.imx_51_t3,
可以针对每个配置生成一个.config,
mkdir imx53_smd
cp .config_imx53_smd imx53_smd/.config
make uImage O=imx53_smd -j4
mkdir imx53_t4
cp .config_imx53_t4 imx53_t4/.config
make uImage O=imx53_t4 -j4
备份M9短信,电话本数据库,
cat /data/data/com.android.providers.telephony/databases/mmssms.db > /sdcard/mmssms.db
cat /sdcard/mmssms.db > /data/data/com.android.providers.telephony/databases/mmssms.db
cat /data/data/com.android.providers.contacts/databases/contacts2.db > contacts2.db
这样备份LINUX
tar -cvpzf /media/Data/linux_bak.tgz –exclude=/proc –exclude=/lost+found –exclude=/media –exclude=/mnt –exclude=/sys /
