KTA55/pITX Software Guide

The DisplayID

Editor saves the parameters in a intermediate file format. The file extension is 'KDD' (Kon-

tron D

isplayID

Data). This file format cannot be used to program the EEPROM.

For transfering this file format into the binary file format for the EEPROM apply the Converter.

4.3.4 Building DisplayID

File



Start the Windows

tool DisplayID.exe.



Use the Editor if you want to modify an existing DisplayID

file or select New to create a

complete new record.



Change respectively enter new parameters.



Save the parameters in a file with the extension 'KDD'.



Open the saved 'KDD'-file using the Converter.



Save the binary file with the extension 'KDB' (Kontron DisplayID

Binary).



Program the EEPROM using the board specific update tool.

4.3.5 EEPROM Panel File Structure

The KTA55/pITX can manage up to 16 separate panel entries. The EEPROM update tool makes it possible to

overwrite each entry. In the Bios Setup choose the menu 'Advanced/Display Configuration/Digital

Display Port 0' and set it to 'LVDS'. Now you can see two additional menus: 'LVDS Flat Panel Type' and

'Brightness Level'. The first menu allows the selection of the required panel.

Attention: If you see only the labels 'Panel 0' to 'Panel 15' the EEPROM is not programmed.

4.3.6 EEPROM Update Tool

You need a EFI tool to update the DisplayID

record. Use a FAT16/FAT32 formatted device (e.g. a USB key)

and copy the update tool and the record to the root directory. Then boot the KTA55 board and press the F7

key during the boot process (calls the boot menu). Choose the entry 'UEFI: Built-in EFI Shell' and press

Enter. After the Shell is active type 'fs0:' and press Enter if you use a USB key - for other boot devices this

label can be changed.

The syntax of the EFI EEPROM update tool is:

KTA55DISP <Option> <Filename>

no option = read a file (KDB-format) and write the content to the EEPROM on panel position 0

-p<n> = read a file (KDB-format) and write the content to the EEPROM on panel position n

-b<val>

= write a backlight brightness value (0 ... 255) to the EEPROM

-backup = read the content of the EEPROM and save it to a file (firmware included)

-update = read the previous backup file and write the content to the EEPROM

Note: do not leave any space between '-p' or '-b' and the parameter

1 2 ... 9 10 11 12 13 14 15 16 17 18 19 ... 24 25
