Debug messages were enabled. In the ./drivers/spi directory, the following were built: built-in.o hspi-s3c64xx.o spi-dev.o spi.o When I open the driver from a user space application, the debug statements come from the SPI-DEV driver. However, I don't see the IOCTL calls in spi-dev.c to change the MODE, CS, BUS, or SPEED. I also need to use two speeds, high and low. The question I have is how do I modify these settings? Thanks in advance. ------------------------------------------------------------------------------ Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev
