Specifications

The default Tcl script is used to set the following system-dependent settings:
• stdio character device
• System timer device
• Default linker memory
• Boot loader status (enabled or disabled)
If the BSP already exists, nios2-bsp overwrites these system-dependent settings.
The default Tcl script is installed at <Nios II EDS install path>/sdk2/bin/bsp-set-defaults.tcl
When creating a new BSP, this utility runs nios2-bsp-create-settings, which creates settings.bsp in <bsp-
dir>.
When updating an existing BSP, this utility runs nios2-bsp-update-settings, which updates settings.bsp in
<bsp-dir>.
After creating or updating the settings.bsp file, this utility runs nios2-bsp-generate-files, which generates
files in <bsp-dir>
Required arguments:
• <bsp-type>: Specifies the type of BSP. This argument is ignored when updating a BSP. This argument
is case-insensitive. The nios2-bsp script supports the following values of <bsp-type>:
• hal
• ucosii
• <bsp-dir>: Path to the BSP directory. Use "." to specify the current directory.
Optional arguments:
• <sopc>: The path name of the .sopcinfo file. Alternatively, specify a directory containing a .sopcinfo file.
In the latter case, the tool finds a file with the extension .sopcinfo. This argument is ignored when
updating a BSP. If you omit this argument, it defaults to the current directory.
• <override>: Options to override defaults. The nios2-bsp script passes most overrides to nios2-bsp-
create-settings or nios2-bsp-update-settings. It also passes the --silent, --verbose, --debug, and
--log options to nios2-bsp-generate-files.
nios2-bsp passes the following overrides to the default Tcl script:
• --default_stdio <device>|none|DONT_CHANGE
Specifies stdio device.
• --default_sys_timer <device>|none|DONT_CHANGE
Specifies system timer device.
• --default_memory_regions DONT_CHANGE
Suppresses creation of new default memory regions when updating a BSP. Do not use this option
when creating a new BSP.
• --default_sections_mapping <region>|DONT_CHANGE
Specifies the memory region for the default sections.
• --use_bootloader 0|1|DONT_CHANGE
Specifies whether a boot loader is required.
On a preexisting BSP, the value DONT_CHANGE prevents associated settings from changing their
current value.
Note:
The "--" prefix is stripped when the option is passed to the underlying utility.
