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-like application. With some additional development, NSH will
|
|
someday be a great NuttX application debugger. At present, NSH
|
|
supports the following commands:
|
|
|
|
Command Depends on Configuration
|
|
---------- --------------------------
|
|
cat CONFIG_NFILE_DESCRIPTORS > 0
|
|
cp CONFIG_NFILE_DESCRIPTORS > 0
|
|
echo --
|
|
exec --
|
|
exit --
|
|
help --
|
|
ifconfig CONFIG_NET && CONFIG_NSOCKET_DESCRIPTORS > 0
|
|
ls CONFIG_NFILE_DESCRIPTORS > 0
|
|
mkdir !CONFIG_DISABLE_MOUNTPOINT && CONFIG_NFILE_DESCRIPTORS > 0
|
|
mount !CONFIG_DISABLE_MOUNTPOINT && CONFIG_NFILE_DESCRIPTORS > 0
|
|
ps --
|
|
set !CONFIG_DISABLE_ENVIRON
|
|
rm !CONFIG_DISABLE_MOUNTPOINT && CONFIG_NFILE_DESCRIPTORS > 0
|
|
rmdir !CONFIG_DISABLE_MOUNTPOINT && CONFIG_NFILE_DESCRIPTORS > 0
|
|
umount !CONFIG_DISABLE_MOUNTPOINT && CONFIG_NFILE_DESCRIPTORS > 0
|
|
unset !CONFIG_DISABLE_ENVIRON
|
|
|
|
Other behavior of NSH can be modified with the following settings in
|
|
the configs/<board-name>/defconfig file:
|
|
|
|
* CONFIG_NSH_IOBUFFERSIZE
|
|
Size of a static I/O buffer used for file access (ignored if
|
|
there is no filesystem).
|
|
|
|
* CONFIG_NSH_STRERROR
|
|
strerror(errno) makes more readable output but strerror() is
|
|
very large and will not be used unless this setting is 'y'
|
|
|
|
* CONFIG_EXAMPLES_NSH_TELNET
|
|
By default, NSH is configured to use the serial console.
|
|
If CONFIG_EXAMPLES_NSH_TELNET is set to 'y', then a TELENET
|
|
server front-end is selected. When this option is provided,
|
|
you must log into NuttX remotely using telnet in order to
|
|
access NSH.
|
|
|
|
If CONFIG_EXAMPLES_NSH_TELNET is selected, then there some other
|
|
configuration settings that apply:
|
|
|
|
* CONFIG_EXAMPLES_NSH_IOBUFFER_SIZE
|
|
Determines the size of the I/O buffer to use for sending/
|
|
receiving TELNET commands/reponses
|
|
|
|
* CONFIG_EXAMPLES_NSH_CMD_SIZE
|
|
The size of one parsed NSH command
|
|
|
|
* CONFIG_EXAMPLES_NSH_STACKSIZE
|
|
The stack size to use when spawning new threads as new TELNET
|
|
connections are established.
|
|
|
|
* CONFIG_EXAMPLES_NSH_DHCPC
|
|
Obtain the the IP address via DHCP.
|
|
|
|
* CONFIG_EXAMPLES_NSH_IPADDR
|
|
If CONFIG_EXAMPLES_NSH_DHCPC is NOT set, then the static IP
|
|
address must be provided.
|
|
|
|
* CONFIG_EXAMPLES_NSH_DRIPADDR
|
|
Default router IP address
|
|
|
|
* CONFIG_EXAMPLES_NSH_NETMASK
|
|
Network mask
|
|
|
|
* CONFIG_EXAMPLES_NSH_NOMAC
|
|
Set if your ethernet hardware has no built-in MAC address.
|
|
If set, a bogus MAC will be assigned.
|
|
|
|
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.

|
|
when CONFIG_EXAMPLES_MOUNT_DEVNAME is not defined. The
|
|
default is zero (meaning that "/dev/ram0" will be used).
|
|
|
|
examples/null

|

|
|
up new NuttX architectures.
|
|
|
|
