Using SPI

Fri May 05, 2006 12:01 pm

Has anyone successfully used the Linux SPI devices /dev/spi/<x> ?

Using kernel with the appropriate maxim patches I cannot get SPI to send data in a deterministic manner.
Most of the time the output is correct as observed with an oscilloscope. But too often only spikes are output instead of the data.

Turning on the internal loopback it seems that most data is sent they way it should but not even on internal loopback all data is correct.

Has anyone had any experience with this?
