Overview
--------
The LS1043A Reference Design Board (RDB) is a high-performance computing,
evaluation, and development platform that supports the QorIQ LS1043A
LayerScape Architecture processor. The LS1043ARDB provides SW development
platform for the Freescale LS1043A processor series, with a complete
debugging environment. The LS1043A RDB is lead-free and RoHS-compliant.
