Hi all,
I have RF board that I need to connect to my FriendlyARM.
The RF board can be communicated through SPI only.
Is there any suggestions on how to connected?
Thanks

At least one SPI native S3C2440 is routed to the "IO" connector on the Mini2440, nothing is on it at the moment. You need to cinnect your device CLK/CDAT and at least a free GPIO to act as a CS (chip select).
Then of course when that is done and the kernel has the interface registered, you need the specific driver for your device..

I need some clarification
Is the spi driver implemented for the mini2440 board and is it compiled and included in the kernel shipped with it?
To access the spi do I need to do it in user space or kernel space?
Is there any example code?
Thanks
