SPI interface

Note: This was originally posted on 10th October 2008 at http://forums.arm.com

Hi all,
I am using an 180 MHz, 200 MIPS ARM920T. My question is
How can one have an SPI interface to a device(any)?? What are the steps involved??

The O.S used is linux. One thing i noticed is there is no SPI in /dev !!!!! It would be really be helpful if any one can suggest or give any link to solve this.

Thanks,
jfor.

I'd suggest looking at a Linux driver for a similar device, and using that as a tutorial.

A UART probably isn't a bad example to pick, as it has send and recieve channels - the only difference is the synchronous bit.

Cheers,
