This project guides new users to start in the White Rabbit “World” with simple experiments. The starting kit uses two SPEC + FMC-DIO cards. Each node allows basic operations such as input timestamping or programmable output pulse generation. Additionally, specific software and gateware layers allow to use it as a standard network interface card implementing the White Rabbit technology functionalities.

The robustness of a White Rabbit Network (WRN) is a broad subject covering methods (HW & SW) which enable to increase overall reliability of a WR-based system. This includes Forward Error Correction (FEC), Quality of Service (QoS) assurance, support of network redundancy, proper network design, thorough diagnostics, and increasing the reliability of network components (i.e. switches, nodes). Here, these methods are described and their implementation sources gathered.

The WandAdapter is a simple PCI-Express x1 card which allows a Wandboard (or any other EDM compatible device) to be connected via it's PCI-Express interface to a mainboard. The card provides power to the Wandboard and breaks out the gigabit ethernet, serial and both USB host and device interfaces. More info at the Wiki page
