Original NIOS Software Driver Development

[Altera_Forum]

Hi, I have a general question in regards of the software driver development for Nios. 

 I have not been able to find any documentation on the Altera's website in regards of the software driver development for the Nios I processor.  I understand in Nios II, you have the IOWR/IORD software driver macros that enables designers to access their custom peripherals instantiated through SOPC.  Does the Nios I processor contain any kind of IOWR/IORD software macros to access "my_peripheral" or is there a totally different procedure that I have to follow?   ---------  In addition to this, is it possible that the original Nios Processsor be able to handle alt_u64 variables?  Thanks

You'll find what you need by reading this (http://www.altera.com/literature/an/an350.pdf) document. I don't recall, exactly, but I believe the volatile qualifier also circumvented the cache with "classic" Nios.
