this will convert script.fex to script.bin and the script.bin file will be written to the microSD card.
reboot
Reboot the board and the new settings would be enabled.
Alternatively, you can do the changes on the microSD card off the board. You would need to
remove the microSD card and explore it in a microSD card reader. You would need to edit the
configuration file script.bin and edit the settings inside. This file is usually located in Script.bin can't
be opened in the binary format so you would need to convert it to .fex file format first. There are
ready-to-use tools that convert script.bin <-> script.fex. Note that script.bin/fex contains
configuration settings and definitions not only for the video output but also for the pin descriptions
and names; power setting and much more. If you really want to modify and customize the default
images (to change port functions, port names, to disable specific peripherals) you would need to be
able to edit the script files. Please refer to the following web page for more information:

2.8 Connecting and calibrating a display
One of the ways to interact with the board is via an external display (with or without touchscreen
component). The 40-pin male connector LCD_CON has the typical 0.1'' pin step. All Olimex
displays have corresponding 40-pin male connector. You would only need a 0.1'' female-female
cable for the hardware connection.
All LCD displays made by Olimex have at least a 0.1'' LCD connector. Going for an LCD output
you would also need need and a cable to attach the display to the board. The cable is sold separately.
The displays recommended for the board at the moment of writing might be found in the table

The displays whose names contain “TS” - include a resistive touch screen component.
The cable used for connection depends on the specific board you are using and more specifically it
depends on the pitch of the LCD connector of the board. We have two cables – both 40-pins ones
but one for the bigger pitch (0.1'') and the other for the smaller one (0.05''). Each of the displays
listed in the table above has two connectors suitable for both cables:
CABLE-IDC40-15cm – 15cm long cable suitable for 0.1'' step connectors –
