fx3load
fxload utility from linux-hotplug project updated for the FX3
...It has been tested on Ubuntu 12.04 with the FX3 development kit (part number CYUSB3KIT-001). Oddly, as of January 2013 Cypress doesn't include this utility with its (open source) Linux SDK but requires developers to purchase a copy of MS Windows to be able to program the board. This SourceForge project contains no new code.
