Why can I not generate the BSP when using Modular SG-DMA and VIC* ?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

The current device driver for modular Scatter-Gather DMA (SG-DMA) does not support enhanced interrupt API. 

In order to get Nios® II Software Build Tools for Ecllipse (SBT4E) generate the BSP for your project, you will need to modify the driver and some related files.

1. Add the following line in dispatcher_sw.tcl so that SBT4E can recognize that the device driver supports both legacy interrupt API and enhanced intterupt API

set_sw_property supported_interrupt_apis "legacy_interrupt_api enhanced_interrupt_api"

2. Your device driver files will also need to be modified to support the enhanced interrupt. Refer to AN595 for further information on how to do this.

*VIC: Vectored Interrupt Controller
