For more information about Tcl scripting with the SBT, refer to the “Tcl Scripts for BSP Settings” chapter.
The Nios® II SBT uses the default Tcl scripts to specify default values for system-dependent settings. System-dependent settings are BSP settings that reference system information in the .sopcinfo file.
The SBT executes the default Tcl script before any user-specified Tcl scripts. As a result, user input overrides settings made by the default Tcl script.
You can pass command-line options to the default Tcl script to override the choices it makes or to prevent it from making changes to settings.
For more information, refer to the “Top Level Tcl Script for BSP Defaults” chapter.
The default Tcl script makes the following choices for you based on your hardware system:
- stdio character device
- System timer device
- Default linker memory regions
- Default linker sections mapping
- Default boot loader settings
The default Tcl scripts use slave descriptors to assign devices.
