examples/romfs
^^^^^^^^^^^^^^
This example exercises the romfs filesystem. Configuration options
include:
* CONFIG_EXAMPLES_ROMFS_RAMDEVNO
The minor device number to use for the ROM disk. The default is
1 (meaning /dev/ram1)
* CONFIG_EXAMPLES_ROMFS_SECTORSIZE
The ROM disk sector size to use. Default is 64.
* CONFIG_EXAMPLES_ROMFS_MOUNTPOINT
The location to mount the ROM disk. Deafault: "/usr/local/share"
