Nios II Embedded Design Suite BSP tools do not support interrupt bridges

Environment

    Quartus® II Subscription Edition
BUILT IN - ARTICLE INTRO SECOND COMPONENT

Critical Issue

Description

Interrupt bridges are not supported by the Nios II Embedded Design Suite Board Support Package (BSP) tools. If interrupt requests (IRQs) are mapped for a module to a CPU interrupt receiver port, the BSP tools publish incorrect information to the system.h file. IRQ IDs appear in the file with a value of -1.

Resolution

Using the information in the Qsys system IRQ map, create a set of #define statements in a new Header File (.h). Because a BSP tool can overwrite the system.h file during generation, do not edit the system.h file.
