NVM Example Main.

The NVM example begins by initializing required board resources. The system clock and basic GPIO pin mapping are established.

A memory location on the Non volatile memory is written with a fixed test pattern which is then read back into a separate buffer. As a basic sanity check, the original write-buffer values are compared with values read to a separate buffer. An LED on the development board is illuminated when there is a match between the written and read data.

Returns

Nothing.
