Hi, I have a wandboard quad and I would like to use SPI to transmit data to a microcontroller. I'm using ubuntu 14.04 (this one : http://www.wandboard.org/images/downloa ... 150511.zip). However, I've never used linux before and I don't know how to acess the bus. I've searched on this forum and I know it has something to do with configuring the kernel, but I don't know how to do that.
Thank you for your help.
