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]
