examples
^^^^^^^^
The examples directory contains several sample applications that
can be linked with nuttx. The specific example is selected in the
configs/<board-name>/defconfig file via the CONFIG_EXAMPLE setting.
For example,
CONFIG_EXAMPLE=ostest
Selects the examples/ostest example.
examples/ostest
^^^^^^^^^^^^^^^
This is the NuttX 'qualification' suite. It attempts to exercise
a broad set of OS functionality. Its coverage is not very extensive
as of this writing, but it is used to qualify each NuttX release.
The behavior of the ostest can be modified with the following
settings in the configs/<board-name>/defconfig file:
* CONFIG_EXAMPLES_OSTEST_LOOPS
Used to control the number of executions of the test. If
undefined, the test executes one time. If defined to be
zero, the test runs forever.
* CONFIG_EXAMPLES_OSTEST_STACKSIZE
Used to create the ostest task. Default is 8192.
examples/nsh
^^^^^^^^^^^^
This directory contains the NuttShell (NSH). This is a simple
shell application. With some additional development, NSH will
someday be a great NuttX application debugger. NSH is described
in its own README located at examples/nsh/README.txt
examples/mount
^^^^^^^^^^^^^^
This contains a simple test of filesystem mountpoints.
* CONFIG_EXAMPLES_MOUNT_DEVNAME
The name of the user-provided block device to mount.
If CONFIG_EXAMPLES_MOUNT_DEVNAME is not provided, then
a RAM disk will be configured.
* CONFIG_EXAMPLES_MOUNT_NSECTORS
The number of "sectors" in the RAM disk used when
CONFIG_EXAMPLES_MOUNT_DEVNAME is not defined.
* CONFIG_EXAMPLES_MOUNT_SECTORSIZE
The size of each sectors in the RAM disk used when
CONFIG_EXAMPLES_MOUNT_DEVNAME is not defined.
* CONFIG_EXAMPLES_MOUNT_RAMDEVNO
The RAM device minor number used to mount the RAM disk used
when CONFIG_EXAMPLES_MOUNT_DEVNAME is not defined. The
default is zero (meaning that "/dev/ram0" will be used).
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"
examples/null
^^^^^^^^^^^^^
This is the do nothing application. It is only used for bringing
up new NuttX architectures.
examples/uip
^^^^^^^^^^^^
This is a port of uIP example application. It includes
conditionally compiled logic to exercise the uIP webserver,
webclient, telnet, smtp, dncpc, and resolver.
examples/netttest
^^^^^^^^^^^^^^^^^
This is a simple network test for verifying client- and server-
functionality in a TCP/IP connection.
examples/udp
^^^^^^^^^^^^
This is a simple network test for verifying client- and server-
functionality over UDP.
examples/pashello
^^^^^^^^^^^^^^^^^
This is "Hello, World" implemented via the Pascal P-Code interpreter
examples/pipe
^^^^^^^^^^^^^
A test of the mkfifo() and pipe() APIs.
* CONFIG_EXAMPLES_PIPE_STACKSIZE
Sets the size of the stack to use when creating the child tasks.
The default size is 1024.
