Kevin Braun / Mbed 2 deprecated LPC4088_RAMtest

Quick but comprehensive memory test for the LPC4088's 32MB of SDRAM. The demonstration program executes a single test pass, though it can be easily modified for multiple passes. If a memory error is detected, the test stops immediately and displays failed results. A single pass is performed in less than one second and every memory location contains unique data.
