The CCAT FPGA is used inside Beckhoff Embedded PCs and Fieldbus Cards. It is internally connected via a PC interface (usually PCIe) and offers interfaces for different Industrial Fieldbusses (e.g. EtherCAT®) Because the device is not yet supported by the linux kernel and therefore not recognized as a standard Ethernet interface you need this driver to run an EtherCAT® master over this interface. For further information about EtherCAT® please see links below:

- Ethernet (EtherCAT® Master)
- GPIO
- SRAM
- FPGA update
- ESC (EtherCAT@ Slave)
- IRQ
- cd into ccat <src_dir>
- make && make install
All functions are implemented in a single kernel module.
To disable some of the functions modify 'static const struct ccat_driver *const drivers[]' in 'module.c' according to your needs.
