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”.

Page 13

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” th at have already been used by the system.

Page 14

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:

SUPERVIVI is developed and maintained by Friendly Arm, 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

(2) setting parameters

Type “s” to set parameters. There are two basic parameters (we don’t recommend to change other parameters):

- Match_type

- Linux command line

The default value for MACH_TYPE is 782. For instance, if your compiled kernel’s MACH_TYPE is 867, you can change this value to boot your kernel. Firstly you need to type the parameter name “mach_type”, then type the value “867”, and finally, type “w” to save your change.

Linux_cmd_line is another very important parameter, for example, to change the kernel boot information and change the login port to serial port 1 (the default serial port is 0), you can do it this way: Linux_cmd_line：noinitrd root=/dev/mtdblock2 init=/linuxrc console=ttySAC0 Type “s”, then the name of the parameter “linux_cmd_line”, enter and then type the new value. Because the parameter string has spaces, it should be quoted: “noinitrd root=/dev/mtdblock2 init=/linuxrc console=ttySAC1,115200”

Those devices include PWM buzzer, RTC real time clock, AD conversion, user test keys, touch screen, LCD, Infrared function, I2C bus, audio input/output and SD card.

2.3.1 Downloading Testing Utilities

The 2440test program is an independent utility. It is based on Samsung’s 2440test utility. We just made some changes for easier use and better experience. In addition we compiled different executables for varied LCDs. Users can download it to RAM via USB and run it. The only difference among those executables is the default LCD output. But they all were compiled from the same source code, we just changed the setting “LCD_TYPE” in the header file “2440test\inc\Option.h”. File Name Notes Memo 2440test_N35.bin The default output is NEC3.5 inch LCD 2440test_A70.bin The default output is Innolux 7 inch LCD 2440test_VGA1024x768.bin The default output is VGA (resolution

1024 x 768 @ 70 Hz)

But they all are compiled from the same source code, we give them a uniform name “ 2440test.bin”.

In the “images\” directory of the shipped CD, you will find a “2440test.bin” and download it from the BIOS interface. (1) Connect the target board to a power supply, a serial port cable, a USB cable and switch the S2 switch to the Nor Flash boot mode. Start a super terminal and the DNW, power on the board. (2) Ensure the USB driver is installed, if so you will see [USB: OK] in the title bar of the DNW otherwise it will show [USB: x]

Meanwhile, the LCD will show the following picture. Note: when compiling the 2440test, you can set the “LCD_TYPE” in the header file “2440test\inc\Option.h” to choose the LCD type, but you cannot define more than one type value, here our default value is LCD_TYPE_N35, i.e. NEC3.5 inch true color screen. The header file 2440test\inc\Option.h has the following definitions: #define LCD_TYPE_N35 1; NEC3.5 inch true color #define LCD_TYPE_A70 2; 7 inch true color #define LCD_TYPE_VGA1024x768 3; VGA module, resolution: 1024x768 @70Hz #define LCD_TYPE LCD_TYPE_N35 If you use the default value, you will see:

For instance, you can set the system’s terminal to a serial port then this terminal will be a serial port terminal whose input and output are both through the serial port terminal without relying on a graphic interface. This is the most popular way in Linux. On system startup, you can point the terminal to a graphic display device (such as LCD, CRT) and the input to the keyboard. This will create another input output system without using a PC.

When a graphic display interface is connected and a GUI is incorporated, a GUI based “command window” will be established. Users can interact with the system via either a real keyboard or a virtual “soft keyboard”. This is what this section describes. In the “Application Programs” subgroup, click on the “terminal” icon, a command line window will popup. You can either connect a USB keyboard (connect it after starting this command line window) to your system or use the keyboard window at the bottom of the screen. You can set the command line window’s display mode by configuring the settings in the “option” menu.

You can browse the directories and files in the system via this browser. Note: Qtopia-2.2.0 doesn’t have a file browser, FriendlyARM migrated one from Qtopia-1.7.0. They have the same functions and interface.

3.1.10 Configuring Network

In the “FriendlyARM” subgroup, click on the “Network Settings” icon:

From this interface we can set various network parameters:

- Static IP address, default setting is 192.168.1.230

- Mask, default setting is 255.255.255.0

- Gateway, default setting is 192.168.1.1

- DNS, default setting is 192.168.1.1

- MAC address, default setting is 08:90:90:90:90:90

Click on “Save” to save these parameters and they are effective right now. After rebooting the system, these settings will still be there. The configuration file that contains the settings is “/etc/eth0-setting”. Note: the “/etc/eth0-setting” file will not exist after reinstalling the system. Clicking on the “Save” button will generate one. Because all products are tested extensively by us, this file exists in your system. Executing the “ifconfig” command will not change this file. In fact, Qtopia has a network setting utility by itself. But its interface is too complicated and may not work sometimes. We didn’t make any change to this utility however created another one shown above. The one Qtopia has is as follows:

3.1.16 Serial Port Assistant

Note: before start this program please connect the serial port your want to test to your board.

- The on board CON1, 2 and 3 are CPU UART0, 1 and 2. UART0 has been converted to RS232, and extended to COM0 via DB9. On system startup it has been set to the console terminal, so it cannot be tested via this utility . The other two ports CON2 and 3 must be converted to RS232 before they can communicate with a PC serial port. (FriendlyARM has a “OneCom” RS232 conversion module) When connect the ports to a PC, please make sure to use a correct serial cable (cross serial line or direct serial line). When connect the OneCom module’s COM2 and COM3 make sure they match your cable

- This program also supports common USB to Serial cables. Now most laptops don’t have serial ports. For the sake of users most of our agents provide those conversion cables. Connecting a USB to Serial cable to your board, you can extend your serial ports. Its device name generally is “/dev/ttyUSB0, 1, 2 and 3”, which implies you can use a USB hub to extend your serial ports. In the “FriendlyARM” subgroup, click on the “Serial Port Assistant” icon to start the interface below:

4.1.2 File Transfer with FTP

Linux or Windows by default has a FTP command line program. Using the FTP service can remotely login a host, transfer files to and from it. The MINI2440 system has a default FTP command line program and starts this service on system startup. To test this service, you can login the sytem via a command line window from a host PC and transfer files to and from it.

Note: please make sure the directory in which to run the FTP commands has the files for FTP test. In this example, it was a “hope.mp3” file.

After the transfer is done, you can check if a “hope.mp3” file exists under “/home/plg”.
