25 The selection between a RAM-based or a FLASH-based disk and file system
26 can be chosen passing Kconfig configuration via the -D command-line switch.
28 RAM-disk Example without any file system
31 The default configurations selects RAM-based disk without any file system.
32 This example only needs additional 96KiB RAM for the RAM-disk and is intended
