Currently, there isn't any convenient way to use SPI from the gumstix.
You need to write some level of kernel driver. I saw a post on the ARM
linux list a few days ago:
Changes will probably be needed to be made to make any of this work
with 2.6.15 (I haven't even had a chance to look at anything yet), but
this appears to be the direction that SSP support is moving for the
Currently, when the robostix is plugged into the gumstix, then it can
