Hi all,

I have a design in which I have to use SPI in order to communicate with an external PIC. I find that it is not enough to select SPI driver in uClinux kernel configuration because when I try to open /dev/spi0 I receive the message: "No such device or address". What am I missing? Where am I wrong?

Thanks in advance

Marco
