Reccomendation for simple SD card (SPI mode) for DE0-nano

Hi All, 

 

I have been working through various attempts to get FAT16 attached via an SD card to a NIOS processor. All I need to do is to quickly load a 10MB file from SD media into SDRAM once, at power up. 

 

Attempts so far have ended up with either just a character interface (which will be way too slow), or the inclusion of IP that has an associated license fee. 

 

Presumably there is a small, open source project, that will talk to a NIOS SPI peripheral, and will readily compile using GCC, hopefully with some examples. 

 

Any thoughts appreciated.
