1 Cirrus Logic Lochnagar Audio Development Board
3 Lochnagar is an evaluation and development board for Cirrus Logic
4 Smart CODEC and Amp devices. It allows the connection of most Cirrus
5 Logic devices on mini-cards, as well as allowing connection of
6 various application processor systems to provide a full evaluation
7 platform. Audio system topology, clocking and power can all be
8 controlled through the Lochnagar, allowing the device under test
9 to be used in a variety of possible use cases.
