| Overview |
| -------- |
| QorIQ LS1012A Reference Design System (LS1012ARDB) is a high-performance |
| development platform, with a complete debugging environment. |
| The LS1012ARDB 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. |
