Fri Jun 3 15:11:36 CEST 2016
QorIQ LS1012A FREEDOM (LS1012AFRDM) is a high-performance
development platform, with a complete debugging environment.
The LS1012AFRDM board supports the QorIQ LS1012A processor and is
optimized to support the high-bandwidth DDR3L memory and
a full complement of high-speed SerDes ports.
