Chapter 2 Getting Started
2.1 System Setup and Configurations
2.1.1 Boot Options
You can select the booting mode by toggling the S2 switch:
When toggling the S2 switch to the “Nor Flash” side the system will boot from on board Nor
Flash. When toggling the S2 switch to the “Nand Flash” side the system will boot from on board
Nand Flash.
This board is shipped with the switch toggled to the Nand Flash side by default it will boot from
Nand Flash. Both its Nor Flash and Nand Flash have been installed an identical BIOS (which
supports both types of Flash. The only difference is that the system will have different startup
windows).
2.1.2 Connecting Peripherals
Connect the MINI2440 board’s serial port to a PC’s serial port with the shipped serial
cable in the package
Connect the MINI2440 board’s Ethernet interface to a PC with the shipped crossover
cable
Connect the shipped 5V power supply adapter to the 5V power supply interface on the
board
Connect a headphone or speaker to the audio input(green) on the board
Connect an LCD touch panel (if the user has one) to the LCD interface on the board
following the data bus’arrow.
Connect the MINI2440 board to a PC with a USB cable.
2.1.3 Setting up Super Terminal
To connect the MINI2440 board to a host PC via a serial cable, you should use a simulated
terminal. There are many tools available. A most widely used one is the MS-Windows’ super
terminal. In Windows9x, you need to install it by checking that option during installation.
Windows2000 and later versions already have it installed by default. We used the super terminal in
Windows XP in all our examples in this manual (Other versions of super terminal might have
different user interfaces). Go to “Start” -> “All Programs” -> “Accessories” -> “Communications”.

High Performance Low Cost Embedded Systems
Click on “Hyper Terminal” and a Window will pop up as below. Click on the “No” button
Click on the “Cancel” button on the following window
Click on the “Yes” button and the “OK” button to the next step
A popup window will require you to name this connection. In this example we typed “ttyS0”.
Windows does not accept names like “COM1” that have already been used by the system.

High Performance Low Cost Embedded Systems
After naming this connection another window will require you to select a serial port that will be
used to connect the MINI2440 board. Here we selected COM1:
Lastly, also the most important step is to set up the port properties. Note: you must select “No” in
the data flow control field otherwise you will only be able to see outputs. In addition the bits per
second should be set to 115200.
After setting up all properties, turn on the board’s power supply, if the connection gets set
properly, you will see a VIVI startup interface. If everything runs fine, please save this connection
for later use

2.2 Power Up
2.2.1 Entering BIOS
The board is shipped with a preinstalled SUPERVIVI in Nor Flash. When the system boots from
Nor Flash it will enter the BIOS and in the meantime the green LED1 on the board will be
flashing. The startup interface is as below:

High Performance Low Cost Embedded Systems
SUPERVIVI is developed and maintained by FriendlyArm, it is based on vivi. It starts with a
function menu. And users can switch between supervivi’s menu interface and command line.
Supervivi can be burned into the Nor Flash with JTAG or run from the Nand Flash. When it is
burned into the Nor Flash and run, users will see its menu. When it is run from the Nand Flash it
will start as command line (note: users need to press down and hold the space key in the super
terminal on system startup otherwise the system will boot to its installed operating system).
Supervivi is mainly for software burning and debugging, and can be used to partition flash drive. It
downloads files via USB. It is easy to use and runs fast. When burning supervivi into the Nor Flash,
you can easily update your Linux or WinCE system, or any other operating system that supports
system boot from the Nand Flash and non OS programs to the Nand Flash such as uCos2, U-boot,
Nboot, 2440test and so on, and then reboot system from the Nand Flash to enjoy your programs.
When burning supervivi to the Nand Flash, it will self detect your operating system and start it. In
addition, with its “Down & Run” function, you can download programs to RAM and run them. This
features software debugging such that you don’t need a simulator. The 2440test utility in the
shipped CD is such a good example.
With supervivi, you can download the Linux kernel image zImage into RAM and run it. You can
even start your system via network by setting up the network boot parameters in supervivi.
Similarly, you can download the WinCE kernel image NK.nb0 to RAM and run it too.
2.2.2 Installing USB Driver
Note: the driver installed here can only work for a USB connection in the BIOS mode. It should
work in conjunction with the dnw.exe executable. After the system enters Linux or WinCE, the

driver will no longer be used.
Installing this USB driver doesn’t need to connect to a board. It is just for the PC system.
Open the shipped CD, double click on “windows 平台工具\usb 下载驱动\ FriendlyARM
USB Download Driver Setup_20090421.exe” to start installing.
The following window will show up:
Click on (“Next”)the middle button.

Now let’s test the USB connection:
Connect the MINI2440 board to a host PC via a USB cable. Toggle the S2 switch to the
“Nor Flash” side.
Turn on the S1 switch, if this is the first time you connect, Windows XP will prompt that a new
USB device is found. Follow the steps below to install a USB driver:
(1) After the following window pops up, check the third option and click on the “Next” button
