git 常用命令
./repo init -u git://192.168.1.25/platform/manifest.git -b r10.2_t4 //初始化
repo init -u ssh://[email protected]/git_repo/manifest.git
git reset --hard ORIG_HEAD //回退到原始版本
git pull //從服務器更新代碼到本地
一、打tag的命令是先hard reset到自己模塊(包含自己和組員)最後一次提交的位置，然後git tag tagname。Tagname的取法要統一，小項目名+完成階段+日期。比如bsp完成了第二階段的目標（7月6號的階段目標），就可以命令tag爲bsp-phase2-20110630
如果碰到沒有全部完成，但是需要進release測試的，就把tag冠名ongoing, 如bsp-ongoing-20110630
如果碰到完成了某個bugfix，就 把BUG Number包含進去，如bsp-PRxxx-20110630 (PR指ProblemResolve,xxx指bug在JIRA系統裏的編號)
二、上傳tag的命令是git push review --tags
一、tag的命名加一個“工程名”的字段即 “工程名-小項目名-完成階段-日期”;這樣曾良均做整合版本的時候就知道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，命令格式爲git tag tagname commit，如git tag kernel_imx-pwrsave-phase2-20110631 cd8c0beb9ecec5e68c0535a416aea972d5f67251
三、上傳某個特定tag的命令是git push review tagname.這樣可以避免把本地自己命名的tag誤傳到服務器。

不同3G模塊移植
【1】
打開：out\target\product\imx51_bbg\root\init.rc
根據不同模塊修改：
#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】
打開：out\target\product\imx51_bbg\system\etc\init.gprs-pppd
根據不同模塊修改：
#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
#/system/bin/pppd /dev/ttyUSB0 115200 mru 1280 mtu 1280 nodetach debug dump defaultroute usepeerdns novj novjccomp noipdefault ipcp-accept-local ipcp-accept-remote connect-delay 5000 linkname ppp0 name "card" password "card"
在我們的工作經常要驗證不同相同源碼不同配置內核版本，比如imx51_evk,imx53_smd,imx53_t4.imx_51_t3,
可以針對每個配置生成一個.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
備份M9短信,電話本數據庫,

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
這樣備份LINUX

cpio解壓絕對路徑解決方法
cpio -iF initramfs --no-absolute-filenames
添加用戶超級權限方法
sudo usermod -aG admin
更改目錄用戶擁有者
sudo chown liufc.liufc 目錄名 -R
samba添加賬戶:
sudo smbpasswd -a LiSi
samba添加用戶權限:
sudo vi /etc/samba/smb.conf
valid users=ZhangSan LiSi
RK內核編譯需要安裝：uudecode
sudo apt-get install sharutils
在init.rc不能直接/sbin/feedplayid
要用 exec /sbin/feedplayid 好了.

$ git clone ssh://[email protected]/git_repo/repo.git
1 、下載 android4.0 倉庫 : ： username 替換成客戶帳號的用戶名
$ mkdir android4.0
$ cd android4.0
$ repo init -u ssh://[email protected]/git_repo/manifest.git
$ repo sync
$ repo start ics-exdroid --all
2 、下載 lichee (linux kernel) 代碼 : username 替換成客戶帳號的用戶名
注意 ： 客戶不要在 android4.0 目錄下面去創建 lichee 目錄 ， 否則初始化時不會生成新的 .rep o
文件，而是用上一級的 .repo 文件。最好在 android4.0 的同一級目錄創建 lichee 目錄。
$ cd ..
$ mkdir lichee
$ cd lichee
$ repo init -u ssh://[email protected]/git_repo/manifest.git -m lichee.xml
$ repo sync
$ repo start lichee-dev --all
3 、 更新 android4.1 代碼： username 替換成客戶帳號的用戶名
$ mkdir android4.1
$ cd android4.1
$ repo init -u ssh://[email protected]/git_repo/manifest.git -b jb-exdroid
$ repo sync
$ repo start jb-exdroid --all
4 、 對應 android4.1 的 lichee 代碼，更新地址如下： username 替換成客戶帳號的用戶名
$ mkdir lichee-jb
$ cd lichee-jb
$ repo init -u ssh://[email protected]/git_repo/manifest.git -b jb-exdroid -m lichee-jb.xml
$ repo sync

MTK代碼只編譯內核new kernel
./mk mbk89_tb_jb2 n k
./mk mbk89_tb_jb2 r bootimage
MTK代碼編譯步驟：
【1】如果修改過底層代碼，通常要make update-api一次：
./mk -o=TARGET_BUILD_VARIANT=user mtk77_cu_ics2 update-api
【2】./mk -o=TARGET_BUILD_VARIANT=user mtk77_cu_ics2 new
【3】把packages\apps\prebuild_app\Phone.apk
複製到

【4】./mk -o=TARGET_BUILD_VARIANT=user mtk77_cu_ics2 systemimage

用adb命令啓動你的Android程序
啓動的方法爲
# am start -n 包(package)名/活動（activity）全路徑
查看包中每個activity的全路徑的方法：
1、安裝並啓動“固件工具箱”
2、進入“App manager”，顯示系統中所有安裝程序，長按想通過命令行啓動的程序。
3、彈出的窗口中選擇"Advanced Freeze",該程序所有的activity就會全部顯示出來
activity有兩種顯示格式，一種直接顯示全路徑，另一種在括號裏顯示相對路徑，相對路徑加上包名即是全路徑。
am start -n com.tdc.test.controller/com.tdc.test.controller.MainActivity

1）地址空間說明
| 1M | 3M | 12M |
|------------|---------------|-----------------------|
| boot | kernel | rootfs |
以下的操作均基於圖示的地址空間分配，您也可以根據實際情況進行調整。
2）燒寫u-boot

sf erase 0 0x100000
mw.b 82000000 ff 100000
tftp 0x82000000 u-boot-200MHZ.bin #如果是hi3516c，使用u-boot-220MHZ.bin
sf write 82000000 0 100000
reset
3）燒寫內核
sf probe 0
sf erase 100000 0x300000
mw.b 82000000 ff 300000
tftp 82000000 uImage
sf write 82000000 100000 300000
4)燒寫文件系統
sf probe 0
sf erase 400000 0xc00000
mw.b 82000000 ff c00000
tftp 82000000 rootfs_64k.jffs2
sf write 82000000 400000 0xc00000
5）設置啓動參數

--注：把abc替換成123
(或者: %s/str1/str2/g 用str2替換文件中所有的str1）
2) 文件內局部替換：
:20,30s#abc#123(如文件內有#，可用/替換,:%s/abc/123/g)
--注：把20行到30行內abc替換成123

windows無法訪問網絡共享解決方法：
打開cmd命令窗口：
1.輸入命令：net use查看你當前與網絡資源的連接，例如驅動器映射、IPC連接。
2.用net use * /del /y命令中斷開所有連接.
3.在重新登錄就可以連接上了

查看 Ubuntu 的版本號，可以採用以下兩種方法：
方法一：
在終端中執行下列指令：
cat
/etc/issue
可以查看當前正在運行的 Ubuntu 的版本號。其輸出結果類似下面的內容：
Ubuntu 10.04 LTS \n \l
方法二：
使用 lsb_release 命令也可以查看 Ubuntu
的版本號，與方法一相比，內容更爲詳細。執行指令如下：
sudo lsb_release -a
複製ssh-keygen -t rsa到git服務器
scp ~/.ssh/id_rsa.pub [email protected]:/home/bill/work/git-test/gitosis-admin/keydir/[email protected]

git push origin master
在192.168.50.250上克隆代碼robot-mt8783
cd ~/work
git clone [email protected]:robot-mt8783.git robot-mt8783
查信號強度命令：
iwpriv wlan0 stat
rssi在無線網絡中表示信號的強度,它隨距離的增大而衰減,通常爲負值,該值越接近零說明信號強度越高。
RSSI持續過低，說明基站收到的上行信號太弱，可能導致解調失敗。 RSSI持續過高，說明收到的上行信號太強，相互之間的干擾太大，也影響信號解調。
SNR是signal to noise ratio的縮寫，即信噪比，它指規定條件下測得的有用信號電平與電磁噪聲電平之間的比值。在任意點上有用信號的幅度與同一點上噪聲信號的幅度之比，並用分貝(dB)表示。峯值與脈衝噪聲相聯繫，有效值則與隨機噪聲相聯繫。
一般是越大越好。
要將目錄logs打包壓縮並分割成多個1M的文件，可以用下面的命令：
tar cjf - logs/ |split -b 1m - logs.tar.bz2.
完成後會產生下列文件：
logs.tar.bz2.aa, logs.tar.bz2.ab, logs.tar.bz2.ac
要解壓的時候只要執行下面的命令就可以了：
cat logs.tar.bz2.a* | tar xj
使用tar對文件加密
$ tar -zcvf - stuff|openssl des3 -salt -k secretpassword | dd of=stuff.des3
將得到一個 stuff.des3文件，用你的密碼替換secretpassword，切勿搞忘了
使用tar對加密文件解壓
$ dd if=stuff.des3 |openssl des3 -d -k secretpassword|tar zxf -
特別注意， 命令最後又一"-",它將釋放所有的文件。
