15.5.4.4. create_driver

Usage

create_driver <name>

Options

  • <name>: Name of device driver.

Description

This command creates a new device driver instance available for the Nios II SBT. This command must precede all others that describe the device driver in its Tcl script. You can only have one create_driver command in each Tcl script. If the create_driver command appears in the Tcl script, the create_sw_package and create_os commands cannot appear.

The name argument is usually distinct from all other device drivers and software packages that the SBT might locate. You can specify driver name identical to another driver if the driver you are describing has a unique version number assignment.

If your driver differs for different operating systems, you need to provide a unique name for each BSP type.

This command is required, unless you use the create_sw_package or create_os commands, as appropriate.
