38.5.6. Board Support Package

The BSP you generate for your Nios II system provides access to the hardware in your system, including the VIC. The VIC driver includes scripts that the BSP generator calls to get default interrupt settings and to validate settings during BSP generation. The Nios® II BSP Editor provides a mechanism to edit these settings and generate a BSP for your Platform Designer design.

The generator produces a vector table file for each VIC in the system, named altera_<name>_vector_tbl.S. The vector table's source path is added to the BSP Makefile for compilation along with other VIC driver source code. Its contents are based on the BSP settings for each VIC's interrupt ports.

The VIC does not support runtime stack checking feature (hal.enable_runtime_stack_checking) in the BSP setting.

VIC BSP Settings

The VIC driver scripts provide settings to the BSP. The number and naming of these settings depends on your hardware system's configuration, specifically, the number of optional shadow register sets in the Nios® II processor, the number of VIC controllers in the system, and the number of interrupt ports each VIC has.

Certain settings apply to all VIC instances in the system, while others apply to a specific VIC instance. Settings that apply to each interrupt port apply only to the specified interrupt port number on that VIC instance.

The remainder of this section lists details and descriptions of each VIC BSP setting.
