KTAM3874/pITX Software Guide
2 U-Boot Setup
The sense of a special Setup part is to avoid expendable changes in the proper operating systems. The
Setup entries are valid for all supported operating systems (e.g. Linux
® , Android TM and Windows ® Em-
bedded Compact). For example if you switch from Linux ® to Android TM or vice versa in the ideal case no
changes will be necessary. The Setup data records are stored in a non-volatile memory (EEPROM) and not in
an erasable script. A possible password input protects from unauthorized access.
The KONTRON Setup provides two configurable main menus:
display
devices
The display menu allows to define one or more boot displays, resolution and mapping of a LCD panel and
backlight parameters. The devices part involves some hardware device settings, e.g. audio controller
enabled or disabled.
ATTENTION
Only the original KONTRON BSPs guarantee the realization of the U-Boot Setup features.
2.1 Setup Command
For a help screen type the command without an argument
setup
Now you can see all the supported sub-commands (menus). Normally the following entries are displayed
display display settings
devices onboard device configuration
password password input
defaults reset all settings to the default values
summary show all actual settings
save save all settings to EEPROM
showdid show the DisplayID TM settings
Syntax example: setup display <Enter>
2.2 Setup Usage
After the execution of a sub-command (e.g. setup devices) the selection of a submenu only requires a
numeric value. Thereafter the real settings are visible. Now you can choose between an alphanumeric
(default) or a numeric input. The alphanumeric presentation illustrates intuitive the right choice. If you
favor the numeric input delete all chars with the <Backspace> key, type the number and then press the
<Enter> key.
After the completion of all changes it is reasonable to control the settings with the summary command.
Syntax:
setup summary <Enter>
