Run Android 2.3 on VirtualBox

This guide is based on Android 2.3 (Gingerbread)  & VirtualBox 4.1.8 running on Microsoft Windows XP.

I choose Android 2.3 because I own a Samsung GALAXY Y (S5360) hand phone which preloaded with Android 2.3. I always test the applications on my computer before I download to the hand phone.

Fun_plug is a collection of applications compiled and packaged by fonz. fun_plug is install on top of D-Link firmware. It is much more powerful than the D-Link original firmware. The following modules is install by default:

  • Lighttpd – a lightweight HTTP server for hosting web pages on the NAS
  • OpenSSH – Secure Shell (which you already used to login to the NAS)
  • Mediatomb – a UPnP media server (alternative to the one provided by Conceptronic)
  • NTP – Network Time Daemon (to synchronize the NAS’ clock with accurate time servers on the Internet)
  • UNFS3 – user-space NFS server (a file server protocol which is often used by computers running Linux)
  • NFS-Utils – NFS server (efficient file transfer and synchronization utility)

This guide is based on fun_plug 0.5 & D-Link DNS-320 ShareCenter and assumes an SATA hard disk is installing to the DNS-320 ShareCenter formatted as ext3.

This is a guide on how to restore from DD-WRT to the original stock firmware. The router that I'm using is TP-Link TL-WR1043 Ver 1.8. 
 
Download
 
Software required
  • WinSCP is an open source free SFTP client, SCP client, FTPS client and FTP client for Windows. Its main function is file transfer between a local and a remote computer. I use this sofware to transfer files from my WinXP computer to the router.
  • PuTTY is a free implementation of Telnet and SSH for Windows and Unix platforms. I use this software to SSH to router & perform flashing command. 
 
Enable SSH
  1. Open up a browser and navigate to http://192.168.1.1 (you should use your own IP)
  2. Login in to DD-WRT.
  3. Goto Services tab and enable SSH
  4. Goto Administration/Management and enable SSH

Copy firmware file to Router

  1. Unzip the downloaded firmware file to any folder, now you have wr1043nv1_en_3_13_10_up(120210).bin in your computer
  2. Run WinSCP
  3. Transfer wr1043nv1_en_3_13_10_up(120210).bin to /tmp of router
  4. You may want to rename the firmware filename to shorter one, I renamed it to a.bin

Start Flashing
  • Run PuTTY (SSH to router)
  • Enter command as blow

cd /tmp

mtd -r write a.bin linux

The router will reboot upon flashing successfully

This tutorial show you how to install PHP on the TP-Link TL-WR1043ND router.

I assume you already have a working installation of OpenWRT on your router. Click here for more about OpenWRT.

You can refer to my previous post http://ediy.com.my/index.php/blog/item/2-openwrt-on-tp-link-tl-wr1043nd-router to upgrade firmware to OpenWRT.


After upgraded the router firmware to OpenWRT backfire, SSH to the router. For Microsoft Windows, I always use PuTTY. You can download PuTTY from http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

DD-WRT on TP-Link TL-WR740N Router

The TP-Link TL-WR740N router use in this tutorial is Ver 4.22. Make sure you download the correct version of firmware. Flashing wrong version firmware will brick the router.

Here is the link. You must download both factory-to-ddwrt.bin & tl-wr740nv4-webflash.bin.


You must upgrade to factory-to-ddwrt.bin before you flash tl-wr740nv4-webflash.bin.

1. Enter 192.168.1.1 from IE to login to the router. Select System Tools then click on Firmware Upgrade.
2. Choose  factory-to-ddwrt.bin which you download to your computer previously.
3. Click Upgrade button to start firmware upgrading.
4. The router will restart automatically after completed upgrade.

Screen shot for upgrade firmware: http://www.divshare.com/download/18183284-fed


5. Login to router again. Now DD-WRT prompt you for changing user name & password.
6. Enter the new router user name & password then click on Change Password button.
7. Enter new user name & password to login to the router.
8. Click on Administration from DD-WRT menu then select Firmware Upgrade.
9. Choose tl-wr740nv4-webflash.bin & click on Upgrade button

The router will upgrade to DD-WRT dated 03-19-12-r18777 which is much more powerful than before.

The Arduino is plug into the USB port of TP-LINK TL-WR1043ND allow the router to control the Arduino.

After upgrade router firmware to Openwrt, Login to it & change the password in order to enable SSH.

SSH to the Router

  1. Run PuTTy
  2. Enter 192.168.1.1 for Host Name (this is the default IP for Openwrt set in TL-WR1043ND)
  3. Change connection type to SSH
  4. Click on Open button
  5. Enter your router username (username is root if you didn't change it)
  6. Enter your password

HTML Onclick Button Image

There is few ways to show image button on the webpage. Here I use <a.

<a target="_parent" href="/newWebPage.php"><img src="/images/light_on.png" alt="Light" /></a>


Above example shows an image with event. newWebPage.php will open if user click on the image.

  1. target="_parent" means open a new page when user click on the image. See http://www.w3schools.com/tags/att_a_target.asp for more information
  2. href= is the action. It will open newWebPage.php when user click on the image.
  3. img src= show the image on the page. It support many formats such as png, jpg, gif, bmp & others. I often use png & gif (animation) format since both support transparent.
  4. alt= will show the text if the associated image is not exist.

 

Note: IE8 and Google Chrome show output differently. There is a rectangular frame around the image if loaded with IE8, while Google Chrome did not show any frame.

Below example execute a javascript function called runCmd with two parameters:

<a href="javascript:runCmd(1,'a')"><img src="/images/fan_on.png" alt="Fan" /></a>



See http://www.w3schools.com/tags/tag_a.asp for more information on how to use <a

Below example shows four images aligned in horizontally:

<a target="_parent" href="/newWebPage.php"><img src="/images/light_on.png" alt="Light" /></a>
<a href="javascript:runCmd(1,'a')"><img src="/images/fan_on.png" alt="Fan" /></a>
<a target="_parent" href="/newWebPage.php"><img src="/images/light_on.png" alt="Light" /></a>
<a href="javascript:runCmd(1,'a')"><img src="/images/fan_on.png" alt="Fan" /></a>
