I build the kernel 3.2.15 and created the SPI device node by following these steps:
1) Determination of the major number of the device node:
The spi device is listed among other devices
2) Creation of the device node:
mknod spi_0 c 163 0
Now that I have the device note if a try to open it via a simple c code it will fail to create the file despcritor: This is code to open the device node:
int fileDescriptor = open("/dev/spi_0", 0_RDWR);
Is there anything that I need to do to be able to use the device node.
Thanks for your help.
