The CF class said,

Software support includes: register definitions, I/O access

macros, and initialization routines with the Nios II HAL.

For complete access to the IDE interface additional software

is required; the Nios II eCOS distribution and Micrium uC/FS

file systems each include such support.

You can also use uclinux.

Hi,hippo.

I'm working with μC/OS-II,now.

I will use eCos and Micrium uC/FS

file systems.

Thanks,hippo.

You should try the hardware using the example code that comes with it. Once that is working you can implement the FAT file system in the HAL using a free FAT file system layer for microcontrollers such as FATFS (ELM Chan) or DOSFS. Both are free and available by looking around google. FATFS is faster...

You should also search around the niosforum a bit too... this question has been asked many many times.
