The reason I would like the system.h is because it provides a complete software description of the Nios II
system hardware,
* The hardware configuration of the peripheral
* The base address
* The IRQ priority (if any)
* A symbolic name for the peripheral
When I used the excalibur.h file in previous Nios designs I used alot of the# defines in my code so when I migrated to Nios II I was expecting system.h to be the same. I have since heard from ALTERA that the only way system. h is generated is when the project is built. For the time being I have generated the excalibur.h file from the SOPC builder so I can do things the way I have done before. But I will need to make time to work out how I should be doing things properly...I suspect with the HAL.
Any way thanks you for your help.
