Advanced Configuration Settings
INtime SDK v7 > References > Advanced Configuration Settings

Both INtime for Windows and INtime Distributed RTOS have a number of configuration settings described as "Advanced" in the associated configuration tools. Many of these settings are changed using the normal user interface so it is not recommended that they are changed directly. However, there may be special occasions when it is necessary to make changes via the "Advanced" interface.

The parameters are described in the following sections. The parameters are organized as a series of values grouped under headings intended to convey their area of usage. In general a parameter name may be up to sixteen characters and its value may be either a string or a numerical value. Strings are stored in single-quotes. Numbers are stored in Intel Hex format (trailing H). They are stored either in the Windows registry (in the case of INtime for Windows) or in a text file (rtconfig.sys, in the case of INtime Distributed RTOS). There is a separate collection for each configured node. Additional parameters controlling the bootloader for INtime Distributed RTOS may be found in the rtboot.ini file in the disk root directory.

Distributed RTOS Initial Application Loader Startup script files

Scriptfiles (.rsc) that are executed during startup are named startup.rsc and are in the /config/{NodeName} directory.

Scriptfiles support all internal commands, can launch programs, and have some basic flow control. Every line is parsed separately, so a command cannot span lines. See the INshell INtime Distributed RTOS Utility page for more information about script files.

Bootloader configuration

The bootload configuration (INtime Distributed RTOS only) may be found in the file /boot/rtboot.ini. There is only one section.

Section Parameter Default Description
BOOT Bootloader configuration
BDEVICE 'msdosfs:/dev/ada0p1' Name of boot partition set by the installer
BDEVICEOPTS 'rw' Boot device options
BOOTFILE '/drtos.bin' Default boot file path
BREAK 0H Value configured by the "Debug on boot" field
0=no break, 1=break to SDM (console), 2=break to SDM (serial port)
FDRIVER 3H Internal value used by kernel - do not change this value
INIFILE '/rtconfig.sys' Configuration settings file path for the boot node
RAMDISK '/init.img' Path name of RAM disk image
RAMDISK_ADDR 0H RAM disk address set by the installer
RDEVICE 'ufs:/dev/ada0p2' Name of the root partition set by the installer
RDEVICEOPTS 'rw' Root device options
SHOWUI 1H Show the user interface. Set to 0 to boot without showing the UI.
TIMEOUT 5H Number of seconds to display the UI before booting. If a key is pressed the timeout is canceled. This value is configured by the "Boot Menu Timeout" system setting.
TITLE 'INtime Distributed RTOS' Bootloader title line text
USE_VIDEO 0H Output to video. Setting this to zero causes the bootloader and the operating system to redirect its output to the first serial port (COM1). This value is configured by the "Use Video For Boot" system setting.

 Other parameters are for internal use and should not be modified or removed.
