5.19 2011-03-12 Gregory Nutt <gnutt@nuttx.org>
* Initial version of the apps/ directory was released as contributed by
Uros Platise.
6.0 2011-03-21 Gregory Nutt <gnutt@nuttx.org>
* README.txt -- README cosmetics
* hello/ -- hello world minor changes
* Makefile -- Makefile cosmetics (I am slowly adding the Darjeeling JVM)
* Make.defs -- New file adds common make definitions for applications.
* hello/Makefile -- Now uses new Make.defs definitions. Added README.txt.
* apps/poweroff -- New application to turn off board power.
* Moved NSH library, netutils, and examples from the nuttx/ directory to
the apps/ directory
* Moved exec_nuttapp machinery into the nuttapp/ directory.
6.1 2011-04-10 Gregory Nutt <gnutt@nuttx.org>
* Creation of auto-generated header files now occurs during the context
build phase.
* Added sdcard insert and eject, nsh command '?' and some code remarks
* Renamed nuttapp to namedapp
* namedapp/binfs.c -- Create a tiny filesystem that can be used
to show the internal named apps under /bin.
* Numerous fixes to build system required to support building with native
Windows toolchain.
6.2 2011-05-06 Gregory Nutt <gnutt@nuttx.org>
* apps/examples/nxffs: Add a test a a configuration that will be used to
verify NXFFS.
6.3 2011-05-15 Gregory Nutt <gnutt@nuttx.org>
* apps/interpreter: Add a directory to hold interpreters. The Pascal add-
on module now installs and builds under this directory.
* apps/interpreter/ficl: Added logic to build Ficl (the "Forth Inspired
Command Language"). See http://ficl.sourceforge.net/.
* apps/netutils/dhcpc, dhcpcd, and tftp. If these directories are included
in the configuration but CONFIG_NET_UDP is disable (which is not very wise),
then a make error occurs because tools/mkdep.sh is called with no files.
* system/free: Move Uros' custom free command from vsn/free
* system/install: Add a new install command submitted by Uros Platise.
* examples/rgmp. Add a placeholder for an RGMP build example.
RGMP is a project for running GPOS and RTOS simultaneously on
multi-processor platforms. See http://rgmp.sourceforge.net/wiki/index.php/Main_Page
for further information about RGMP. NOTE: This is an empty example
on initial check-in.
6.4 2011-06-06 Gregory Nutt <gnutt@nuttx.org>
* nshlib/nsh_netcmds.c: If a network device name and IP address are provided
with the ifconfig command, then this command will now set the network address.
(Contributed by Yu Qiang).
* netutils/ftpc: A library to support client-side FTP.
* examples/ftpc: A simple add-on to the NSH. From NSH, you can start
this simple FTP shell to transfer files to/from a remote FTP server.
6.5 2011-06-21 Gregory Nutt <gnutt@nuttx.org>
* netutils/ftpc: Simpflication and size reduction.
6.6 2011-07-11 Gregory Nutt <gnutt@nuttx.org>
* Make.defs, namedapp/namedapp.c: Several structural changes made to get a
clean compile under the ez80 ZDS-II toolchain (no design changes).
* apps/examples/buttons: Add a test for the new standardized button interfaces
* apps/examples/nxtext: Add another NX graphics test. This one focus on
placing text on the background while pop-up windows occur. Text should
continue to update normally with or without the popup windows present.
6.7 2011-08-02 Gregory Nutt <gnutt@nuttx.org>
* apps/examples/nx and nxtext: These examples can now be built as NSH
"built-in" commands.
* apps/examples/nxhello: The simplest graphics example: It just says
"Hello, World!" in the center of the display. This example can also be
built as an NSH "built-in" command.
* apps/examples/nx, ntext, and nxhello: All updated to use the new
NuttX font interfaces.
* apps/examples/nximage: Another super simple graphics example: It just puts
the NuttX logo in the center of the display. This example can also be
built as an NSH "built-in" command.
* apps/examples/usbstorage: Can now be built as two NSH "built-in" commands:
'msconn' will connect the USB mass storage device; 'msdis' will disconnect
the USB storage device.
* apps/examples/nx*: All NX header files moved from nuttx/include/nuttx to
nuttx/include/nuttx/nx.
* apps/examples/usbstorage: Added instrumentation to monitor memory usage
to check for memory leaks in the USB storage driver.
* apps/examples/nxhello/nxhello_bkgd.c: Fix handling of allocated glyph
memory.
6.8 2011-08-11 Gregory Nutt <gnutt@nuttx.org>
* apps/examples/nxlines: Added a test for NX line drawing capabilities.
6.9 2011-09-11 Gregory Nutt <gnutt@nuttx.org>
* apps/examples/nxlines: Extend the line drawing text to include drawing
of circles.
* apps/system/i2c: Add an I2C test tool that should help to bring up I2C
devices (when it is fully functional).
* apps/nshlib/nsh_timcmds.c: Add the date command that can be used to
show or set the time (only if CONFIG_RTC is set).
6.10 2011-10-06 Gregory Nutt <gnutt@nuttx.org>
* apps/system/i2c: Add repitition and address auto-incrementing so that
and command can be executed numerous times. Add a new verify command
that will write to a register, read from register, and verify that
returned value.
* apps/graphics/tiff: Add a library that can be used to create TIFF files.
* apps/examples/tiff: Add a unit test for the TIFF file creation logic
* apps/examples/lcdrw: Add a test to verify if you can or can or read
data from an LCD correctly.
* apps/examples/usbterm: A USB terminal example.. more of a USB chat or
serial bridge: Data received on local console echoed via USB serial;
data received on USB serial is echoed on the local console.
* apps/examples/touchscreen: Add a simple, generic test for any
touschscreen driver.
* Makefile: The apps/ Makefile now checks for an apps/external directory
or symbolic link. If such a directory/link exists (and has a Makefile),
it will be added to the apps/ build. This allows external directories
to be included into the apps/ build by simply creating a symbolic link.
6.11 2011-11-12 Gregory Nutt <gnutt@nuttx.org>
(No major changes from 6.10)
6.12 2011-12-06 Gregory Nutt <gnutt@nuttx.org>
* apps/examples/buttons: The button test can now be executed as an NSH
built in command.
6.13 2012-12-26 Gregory Nutt <gnutt@nuttx.org>
* apps/examples/dhcpd: May now be built as an NSH built-in application
by setting CONFIG_NSH_BUILTIN_APPS.
* apps/netutils/dhcpd/dhcpd.c: Fix several problems using host order address
where network addresses expected (and vice versa).
* apps/examples/nettest: May now be built as an NSH built-in application
by setting CONFIG_NSH_BUILTIN_APPS.
* apps/examples/nettest: Correct some build issues with the nettest is
built for performance evaluation.
* apps/examples/adc: Add a very simple test to drive and test an ADC
driver.
* apps/examples/pwm: Add an NSH PWM command to drive and test a PWM
driver.
* apps/examples/can: Add an NSH CAN command to drive and test a CAN
driver in loopback mode.
6.14 2012-01-15 Gregory Nutt <gnutt@nuttx.org>
* apps/examples/buttons/main.c: The test needs to call up_buttoninit() to
properly configure the button interrupt GPIOs.
* apps/examples/pwm: Add support to test the pulse count option recently
added to the PWM interface.
6.15 2012-02-12 Gregory Nutt <gnutt@nuttx.org>
* apps/nshlib/nsh_serial.c and nsh_usbdev.c: If NuttX is configured to use
a USB serial console, then NSH needs to wait until the USB console is
connected and available.
* apps/examples/composite: Add a test of the USB composite device.
* apps/examples/Telnetd: Move the tiny uIP shell example from
netutils/Telnetd to examples/Telnetd. Enhanced the Telnetd daemon so that
it supports Telnetd via a TTY device driver: A new TTY device driver is
created when each new Telnet connection is created. The shell thread
is started with stdin, stdout, and stderr mapped to the TTY device.
* netutils/Telnetd: The old uIP Telnet demo is gone. In its place is a new
Telnet infrastructure. The new Telnet daemon creates sessions that are
"wrapped" as character devices and mapped to stdin, stdout, and stderr.
Now the Telnet session can be inherited by spawned tasks.
* examples/Telnetd: Add a test for the new Telnet daemon.
* examples/Telnetd/telnetd_driver.c: Move the internal socket structure from
the daemon's socket array into the driver's state data so that it will be
independent from the the Telnetd daemon.
* apps/system/readline: Moved the old nuttx/lib/stdio/lib_fgets.c here
and renamed it as readline(). The old fgets was simplied and the overloaded
readline functionality was removed.
* apps/netutils/ftpd: Add an FTPD server (does not even compile on initial
checkin).
* apps/examples/ftpd: Add a test for the FTPD server (untest on initial
check-in).
* apps/nshlib/nsh_fscmds.c: Add support for a 'dmesg' command that will
dump the system log if CONFIG_SYSLOG is selected.
6.16 2012-03-10 Gregory Nutt <gnutt@nuttx.org>
* apps/examples/qencoder: Add a quadrature driver test.
* apps/examples/ostest/fpu.c: Add a test to verify that FPU registers
are properly saved and restored on context switches.
* apps/system/readline/readline.c: readline() will now treat either a
backspace or a DEL character as a backspace (i.e., deleting the character
to the left of the cursor). This makes NSH less dependent on particular
keyboard mappings of the Backspace key. Submitted by Mike Smith.
* apps/examples/cdcacm: An example that illustrates how the CDC/ACM driver
may to connected and disconnected through software control.
* apps/examples/nsh/nsh_main.c: If available, call up_cxxinitialize() to
initialize all statically defined C++ classes.
* apps/nshlib: Now supports a USB serial device for NSH console I/O. This
allows NSH to be used on boards that have USB but no serial connectors.
6.17 2012-04-14 Gregory Nutt <gnutt@nuttx.org>
* apps/examples/can: Add conditional compilation so that the test can be
configured to only send messages or to only receive messages. This will
let the test work in other modes than simple loopback testing.
* apps/examples/hello and apps/examples/ostest: Can now be built as NSH
built-int functions.
* vsn/hello: Removed. The modified apps/examples/hello is enough "Hello,
World!"
* apps/examples/nxconsole: Add a test of the NX console device.
* apps/examples/nxconsole: The NX console example now supports running
the NuttShell (NSH) within an NX window.
* apps/system/readline: Now uses standard definitions from
include/nuttx/ascii.h and vt100.h
* Kconfig, */Kconfig: Added skeleton Kconfig files to all directories that
may need them.
6.18 2012-05-19 Gregory Nutt <gnutt@nuttx.org>
* Kconfig: Continued Kconfig file updates (no longer tracking on a per-file
basis in the ChangeLog)
* apps/examples/watchdog: Add a watchdog timer example.
* apps/examples/tiff: Fix wrong path used for temporary file.
* apps/examples/touchscreen: Standardize the board-specific, touchscreen
initialization interfaces.
6.19 2012-06-15 Gregory Nutt <gnutt@nuttx.org>
* apps/nshlib/nsh_usbdev.c: Add the capability to use an arbitrary USB
device as the console (not necessarily /dev/console). This is a useful
option because then you can still use the serial console to debug with.
* apps/nshlib/nsh_usbdev.c: User now has to press ENTER 3 times before
USB console will start. Otherwise, the USB console starts before there
is anyone at the other end to listen.
* apps/nshlib/nsh_usbdev.c and nsh_consolemain.c: Add support for the USB
capability when a USB console is used.
* apps/nshlib/nsh_fscmds.c: Add the 'mv' command
6.20 2012-07-12 Gregory Nutt <gnutt@nuttx.org>
* namedapp/exec_namedapp.c - Correct an error when round robin scheduling
is enabled. The priority of the new, named application was erroneously
being set to the priority of the parent thread; losing its configured
priority. Reported by Mike Smith.
6.21 2012-08-25 Gregory Nutt <gnutt@nuttx.org>
* apps/include/: Stylistic clean-up of all header files.
* apps/modbus and apps/include/modbus: A port of freemodbus-v1.5.0
has been added to the NuttX apps/ source tree.
* apps/examples/modbus: A port of the freemodbus-v1.5.0 "demo"
program that will be used to verify the FreeModBus port
* apps/modbus: Don't use strerror(). It is just too big.
* apps/modbus: Add CONFIG_MB_TERMIOS. If the driver doesn't support
termios ioctls, then don't bother trying to configure the baud, parity
etc.
* apps/nshlib: If waitpid() is supported, then NSH now catches the
return value from spawned applications (provided by Mike Smith)
* apps/nshlib: Lock the scheduler while starting built-in applications
in order to eliminate race conditions (also from Mike Smith).
* apps/examples/adc, pwm, and qencoder: Add support for testing
devices with multiple ADC, PWM, and QE devices.
* apps/nshlib/nsh_mntcmds.c: Separated mount-related commands out of
nsh_fscmds.c. Extended to the mount command so that if no arguments
are provided, then the current mountpoints are enumerated.
* apps/nshlib/nsh_mntcmds.c: Add an NSH df command to list the
properties of mounted file systems.
* apps/nshlib/nsh_parse.c: Extend help command options. 'help' with
no arguments outputs a short list of commands. With -v lists all
command line details. A command name can be added to just get
help on one command.
* system/readline.c: If character input/output is interrupted by a
signal, then readline() will try the read/write again.
* apps/*/Make.defs: Numerous fixes needed to use the automated
configuration (from Richard Cochran).
6.22 2012-09-29 Gregory Nutt <gnutt@nuttx.org>
* apps/netutils/thttpd/thttpd_cgi.c: Missing NULL in argv[]
list (contributed by Kate).
* apps/nshlib/nsh_parse.c: CONFIG_NSH_DISABLE_WGET not CONFIG_NSH_DISABLE_GET
in one location (found by Kate).
* apps/examples/ostest/prioinherit.c: Limit the number of test
threads to no more than 3 of each priority. Bad things happen
when the existing logic tried to created several hundred test
treads!
* apps/nshlib/nsh.h: Both CONFIG_LIBC_STRERROR and CONFIG_NSH_STRERROR
must be defined to use strerror() with NSH.
* apps/examples/*/*_main.c, system/i2c/i2c_main.c, and others: Added
configuration variable CONFIG_USER_ENTRYPOINT that may be used to change
the default entry from user_start to some other symbol. Contributed by
Kate.
* apps/netutils/webserver/httpd/c: Fix a typo that as introduced in
version r4402: 'lese' instead of 'else' (Noted by Max Holtzberg).
* tools/mkfsdata.pl: The uIP web server CGI image making perl script was
moved from apps/netutils/webserver/makefsdata to nuttx/tools/mkfsdata.pl
(Part of a larger change submitted by Max Holtzberg).
* apps/netutils/webserver, apps/examples/uip, and apps/include/netutils/httpd.h:
The "canned" version of the uIP web servers content that was at
netutils/webserver/httpd_fsdata.c has been replaced with a dynamically
built configuration located at apps/examples/uip (Contributed by
Max Holtzberg).
* apps/netutils/webserver: Several inenhancements from Kate including the
ability to elide scripting and SERVER headers and the ability to map
files into memory before transferring them.
* apps/netutils/webserver: Add ability to map a URL to CGI function.
Contributed by Kate.
* apps/nshlib/nsh_mntcmds.c: The changes of 6.21 introduced holes in the
error handling: Now the number of arguments to mount can be 0 or 4.
Additional parameter checking is required to prevent mysterious errors
(submiteed by Kate).
* apps/netutils/webserver/httpd_mmap.c: Fix errors when the mmap()
length is zero (submitted by Kate).
* apps/netutils/webserver/httpd_sendfile.c: Add and option,
CONFIG_NETUTILS_HTTPD_SENDFILE to transfer files using the NuttX
sendfile() interface.
* apps/netutils/discover: A UDP network discovery utility contributed
by Max Holtzberg.
* apps/examples/discover: A test example for the UDP network discovery
utility (also contribed by Max Holtzberg).
* apps/examples/*/main.c: Too many files called main.c. Each renamed
to something unique so that they will not collide in the archive.
* apps/netutils/xmlrpc: The Embeddable Lightweight XML-RPC Server
discussed at http://www.drdobbs.com/web-development/\
an-embeddable-lightweight-xml-rpc-server/184405364. Contributed by
Max Holtzberg.
* apps/netutils/uip_listenon.c: Logic in uip_server.c that creates
the listening socket was moved to this new file to support re-use.
Contributed by Kate.
* apps/netutils/webserver/httpd.c: The option CONFIG_NETUTILS_HTTPD_SINGLECONNECT
can now be used to limit the server to a single thread. Option
CONFIG_NETUTILS_HTTPD_TIMEOUT can be used to generate HTTP 408 errors.
Both from Kate.
* apps/netutils/webserver/httpd.c: Improvements to HTTP parser from
Kate.
* apps/netutils/webserver/httpd.c: Add support for Keep-alive connections
(from Kate).
* apps/NxWidget/Kconfig: This is a kludge. I created this NxWidgets
directory that ONLY contains Kconfig. NxWidgets does not live in
either the nuttx/ or the apps/ source trees. This kludge makes it
possible to configure NxWidgets/NxWM without too much trouble (with
the tradeoff being a kind ugly structure and some maintenance issues).
* apps/examples/Make.defs: Missing support for apps/examples/watchdog.
* apps/NxWidgets/Kconfig: Add option to turn on the memory monitor
feature of the NxWidgets/NxWM unit tests.
6.23 2012-11-05 Gregory Nutt <gnutt@nuttx.org>
* vsn: Moved all NSH commands from vsn/ to system/. Deleted the vsn/
directory.
* Makefile: Change order of includes when CONFIG_NEWCONFIG=y. In
that case, namedapp must be included first so that the namedapp
context is established first. If the namedapp context is established
later, it will overwrite any existing namedapp_list.h and nameapp_proto.h
files.
* CONFIG_EXAMPLES_*: To make things consistent, changed all occurrences
of CONFIG_EXAMPLE_* to CONFIG_EXAMPLES_*.
* Kconfig: Fleshed out apps/examples/adc/Kconfig and apps/examples/wget/Kconfig.
There are still a LOT of empty, stub Kconfig files.
* Kconfig: Fleshed out apps/examples/buttons/Kconfig. There are still a LOT
of empty, stub Kconfig files.
* apps/netutils/webserver/httpd.c: Fix a bug that I introduced in
recent check-ins (Darcy Gong).
* apps/netutils/webclient/webclient.c: Fix another but that I introduced
when I was trying to add correct handling for loss of connection (Darcy Gong)
* apps/nshlib/nsh_telnetd.c: Add support for login to Telnet session via
username and password (Darcy Gong).
* apps/netutils/resolv/resolv.c (and files using the DNS resolver): Various
DNS address resolution improvements from Darcy Gong.
* apps/nshlib/nsh_netcmds.c: The ping command now passes a maximum round
trip time to uip_icmpping(). This allows pinging of hosts on complex
networks where the ICMP ECHO round trip time may exceed the ping interval.
* apps/examples/nxtext/nxtext_main.c: Fix bad conditional compilation
when CONFIG_NX_KBD is not defined. Submitted by Petteri Aimonen.
* apps/examples/nximage/nximage_main.c: Add a 5 second delay after the
NX logo is presented so that there is time for the image to be verified.
Suggested by Petteri Aimonen.
* apps/Makefile: Small change that reduces the number of shell invocations
by one (Mike Smith).
* apps/examples/elf: Test example for the ELF loader.
* apps/examples/elf: The ELF module test example appears fully functional.
* apps/netutils/json: Add a snapshot of the cJSON project. Contributed by
Darcy Gong.
* apps/examples/json: Test example for cJSON from Darcy Gong
* apps/nshlib/nsh_netinit.c: Fix static IP DNS problem (Darcy Gong)
* apps/netutils/resolv/resolv.c: DNS fixes from Darcy Gong.
* COPYING: Licensing information added.
* apps/netutils/codec and include/netutils/urldecode.h, base64.h, and md5.h:
A port of the BASE46, MD5 and URL CODEC library from Darcy Gong.
* nsnlib/nsh_codeccmd.c: NSH commands to use the CODEC library.
Contributed by Darcy Gong.
* apps/examples/wgetjson: Test example contributed by Darcy Gong
* apps/examples/cxxtest: A test for the uClibc++ library provided by
Qiang Yu and the RGMP team.
* apps/netutils/webclient, apps/netutils.codes, and apps/examples/wgetjson:
Add support for wget POST interface. Contributed by Darcy Gong.
* apps/examples/relays: A relay example contributed by Darcy Gong.
* apps/nshlib/nsh_netcmds: Add ifup and ifdown commands (from Darcy
Gong).
* apps/nshlib/nsh_netcmds: Extend the ifconfig command so that it
supports setting IP addresses, network masks, name server addresses,
and hardware address (from Darcy Gong).
6.24 2012-12-20 Gregory Nutt <gnutt@nuttx.org>
* apps/examples/ostest/roundrobin.c: Replace large tables with
algorithmic prime number generation. This allows the roundrobin
test to run on platforms with minimal SRAM (Freddie Chopin).
* apps/nshlib/nsh_dbgcmds.c: Add hexdump command to dump the contents
of a file (or character device) to the console Contributed by Petteri
Aimonen.
* apps/examples/modbus: Fixes from Freddie Chopin
* apps/examples/modbus/Kconfig: Kconfig logic for FreeModBus contributed
by Freddie Chopin.
* Makefile, */Makefile: Various fixes for Windows native build. Now uses
make foreach loops instead of shell loops.
* apps/examples/elf/test/*/Makefile: OSX doesn't support install -D, use
mkdir -p then install without the -D. From Mike Smith.
* apps/examples/relays/Makefile: Reduced stack requirement (Darcy Gong).
* apps/nshlib and apps/netutils/dhcpc: Extend the NSH ifconfig command plus
various DHCPC improvements(Darcy Gong).
* apps/nshlib/nsh_apps.c: Fix compilation errors when CONFIG_NSH_DISABLEBG=y.
From Freddie Chopin.
* Rename CONFIG_PCODE and CONFIG_FICL as CONFIG_INTERPRETERS_PCODE and
CONFIG_INTERPRETERS_FICL for consistency with other configuration naming.
* apps/examples/keypadtest: A keypad test example contributed by Denis
Carikli.
* apps/examples/elf and nxflat: If CONFIG_BINFMT_EXEPATH is defined, these
tests will now use a relative path to the program and expect the binfmt/
logic to find the absolute path to the program using the PATH variable.
6.25 2013-02-01 Gregory Nutt <gnutt@nuttx.org>
* Makefiles: Removed dependency of distclean on clean in most top-level
files. It makes sense for 'leaf' Makefiles to have this dependency,
but it does not make sense for upper-level Makefiles.
* apps/namedapp/: Renamed to builtins in preparation for another change.
* .context: Removed the .context kludge. This caused lots of problems
when changing configurations because there is no easy way to get the
system to rebuild the context. Now, the context will be rebuilt
whenever there is a change in either .config or the Makefile.
* apps/builtin/registry: Updated new built-in registration logic to handle
cases where (1) old apps/.config is used, and (2) applications ared
removed, not just added.
* apps/examples/nettest/Makefile: Fix an error that crept in during
some of the recent, massive build system changes.
* apps/builtin/Makefile: Need to have auto-generated header files
in place early in the dependency generation phase to avoid warnings.
It is not important if they are only stubbed out header files at
this build phase.
* apps/examples/hidbkd: Now supports decoding of encoded special keys
if CONFIG_EXAMPLES_HIDKBD_ENCODED is defined.
* apps/examples/hidbkd: Add support for decoding key release events
as well. However, the USB HID keyboard drier has not yet been
updated to detect key release events. That is kind of tricky in
the USB HID keyboard report data.
* apps/examples/wlan: Remove non-functional example.
* apps/examples/ostest/vfork.c: Added a test of vfork().
* apps/exampes/posix_spawn: Added a test of posix_spawn().
* apps/examples/ostest: Extend signal handler test to catch
death-of-child signals (SIGCHLD).
* apps/examples/ostest/waitpid.c: Add a test for waitpid(), waitid(),
and wait().
* builtin/binfs.c: Add hooks for dup() method (not implemented).
* builtin/exec_builtin.c, nshlib/nsh_parse.c, and nshlib/nsh_builtin.c:
NSH now supports re-direction of I/O to files (but still not from).
* builtin/binfs.c: Greatly simplified (it is going to need to be
very lightweight). Now supports open, close, and a new ioctl to recover
the builtin filename. The latter will be needed to support a binfs
binfmt.
* builtin/binfs.c: Move apps/builtin/binfs.c to fs/binfs/fs_binfs.c
CONFIG_APPS_BINDIR rename CONFIG_FS_BINFS
* apps/include/builtin.h: Some of the content of
apps/include/apps.h moved to include/nuttx/binfmt/builtin.h.
apps/include/apps.h renamed builtin.h
* apps/builtin/exec_builtins.c: Move builtin
utility functions from apps/builtin/exec_builtins.c to
binfmt/libbuiltin/libbuiltin_utils.c
* apps/nshlib/nsh_mountcmds.c: The block driver/source
argument is now optional. Many files systems do not need
a source and it is really stupid to have to enter a bogus
source parameter.
* apps/nshlib/nsh_fileapp.c: Add the ability to execute a file
from a file system using posix_spawn().
* apps/builtin/: Extensions from Mike Smith.
* apps/examples/ftpd/Makefile: Name ftpd_start is not the name of
the entrypoint. Should be ftpd_main (from Yan T.)
* apps/netutils/telnetd/telnetd_driver: Was stuck in a loop if
recv[from]() ever returned a value <= 0.
* apps/examples/nettest and poll: Complete Kconfig files.
* apps/examples/ostest/waitpid.c: Need to use WEXITSTATUS()
to decode the correct exit status.
* apps/system/usbmonitor: A daemon that can be used to monitor USB
trace outpout.
* apps/nshlib/nsh_usbdev.c, nsh_consolemain.c, nsh_session.c, nsh_script.c:
Add support for a login script. The init.d/rcS script will be executed
once when NSH starts; the .nshrc script will be executed for each session:
Once for serial, once for each USB connection, once for each Telnet
session.
* apps/system/readline: Correct readline() return value. Was not
any returning special values when end-of-file or read errors
occur (it would return an empty string which is not very useful).

Example Built-In Application
Building NuttX with Board-Specific Pieces Outside the Source Tree
General
-------
This folder provides various applications found in sub-directories. These
applications are not inherently a part of NuttX but are provided to help
you develop your own applications. The apps/ directory is a "break away"
part of the configuration that you may choose to use or not.
Directory Location
------------------
The default application directory used by the NuttX build should be named
apps/ (or apps-x.y/ where x.y is the NuttX version number). This apps/
directory should appear in the directory tree at the same level as the
NuttX directory. Like:
.
|- nuttx
|
`- apps
If all of the above conditions are TRUE, then NuttX will be able to
find the application directory. If your application directory has a
different name or is location at a different position, then you will
have to inform the NuttX build system of that location. There are several
ways to do that:
1) You can define CONFIG_APPS_DIR to be the full path to your application
directory in the NuttX configuration file.
2) You can provide the path to the application directory on the command line
like: make APPDIR=<path> or make CONFIG_APPS_DIR=<path>
3) When you configure NuttX using tools/configure.sh, you can provide that
path to the application directory on the configuration command line
like: ./configure.sh -a <app-dir> <board-name>/<config-name>
Built-In Applications
---------------------
NuttX also supports applications that can be started using a name string.
In this case, application entry points with their requirements are gathered
together in two files:
- builtin/builtin_proto.h Entry points, prototype function
- builtin/builtin_list.h Application specific information and requirements
The build occurs in several phases as different build targets are executed:
(1) context, (2) depend, and (3) default (all). Application information is
collected during the make context build phase.
To execute an application function:
exec_builtin() is defined in the nuttx/include/apps/builtin.h
NuttShell (NSH) Built-In Commands
---------------------------------
One use of builtin applications is to provide a way of invoking your custom
application through the NuttShell (NSH) command line. NSH will support
a seamless method invoking the applications, when the following option is
enabled in the NuttX configuration file:
CONFIG_NSH_BUILTIN_APPS=y
Applications registered in the apps/builtin/builtin_list.h file will then
be accessible from the NSH command line. If you type 'help' at the NSH
prompt, you will see a list of the registered commands.
Synchronous Built-In Commands
-----------------------------
By default, built-in commands started from the NSH command line will run
asynchronously with NSH. If you want to force NSH to execute commands
then wait for the command to execute, you can enable that feature by
adding the following to the NuttX configuration file:
CONFIG_SCHED_WAITPID=y
The configuration option enables support for the waitpid() RTOS interface.
When that interface is enabled, NSH will use it to wait, sleeping until
the built-in command executes to completion.
Of course, even with CONFIG_SCHED_WAITPID=y defined, specific commands
can still be forced to run asynchronously by adding the ampersand (&)
after the NSH command.
Application Configuration File
------------------------------
The old-style NuttX configuration uses a special configuration file is
used to configure which applications are to be included in the build.
The source for this file is configs/<board>/<configuration>/appconfig.
The existence of the appconfig file in the board configuration directory\
is sufficient to enable building of applications.
The appconfig file is copied into the apps/ directory as .config when
NuttX is configured. .config is included in the toplevel apps/Makefile.
As a minimum, this configuration file must define files to add to the
CONFIGURED_APPS list like:
CONFIGURED_APPS += examples/hello system/poweroff
The new NuttX configuration uses kconfig-frontends tools and only the
NuttX .config file. The new configuration is indicated by the existence
of the definition CONFIG_NUTTX_NEWCONFIG=y in the NuttX .config file.
If CONFIG_NUTTX_NEWCONFIG is defined, then the Makefile will:
- Assume that there is no apps/.config file and will instead
- Include Make.defs files from each of the subdirectories.
When an application is enabled using the kconfig-frontends tool, then
a new definition is added to the NuttX .config file. For example, if
you want to enable apps/examples/hello then the old apps/.config would
have had:
CONFIGURED_APPS += examples/hello
But in the new configuration there will be no apps/.config file and,
instead, the NuttX .config will have:
CONFIG_EXAMPLES_HELLO=y
This will select the apps/examples/hello in the following way:
- The top-level make will include examples/Make.defs
- examples/Make.defs will set CONFIGURED_APPS += examples/hello
like this:
ifeq ($(CONFIG_EXAMPLES_HELLO),y)
CONFIGURED_APPS += examples/hello
endif
Thus accomplishing the same thing with no apps/.config file.
Example Built-In Application
----------------------------
An example application skeleton can be found under the examples/hello
sub-directory. This example shows how a builtin application can be added
to the project. One must define:
Old configuration method:
1. Create sub-directory as: appname
2. In this directory there should be:
- A Makefile, and
- The application source code.
3. The application source code should provide the entry point:
appname_main()
4. Set the requirements in the file: Makefile, specially the lines:
APPNAME = appname
PRIORITY = SCHED_PRIORITY_DEFAULT
STACKSIZE = 768
ASRCS = asm source file list as a.asm b.asm ...
CSRCS = C source file list as foo1.c foo2.c ..
Look at some of the other Makefiles for examples. Note the
special registration logic needed for the context: target
5. Add the to the application to the CONFIGIURED_APPS in the
apps/.config file:
CONFIGURED_APPS += appname
New Configuration Method:
1. Create sub-directory as: appname
2. In this directory there should be:
- A Make.defs file that would be included by the apps/Makefile
- A Kconfig file that would be used by the configuration tool (see
misc/tools/kconfig-language.txt). This Kconfig file should be
included by the apps/Kconfig file
- A Makefile, and
- The application source code.
3. The application source code should provide the entry point:
appname_main()
4. Set the requirements in the file: Makefile, specially the lines:
APPNAME = appname
PRIORITY = SCHED_PRIORITY_DEFAULT
STACKSIZE = 768
ASRCS = asm source file list as a.asm b.asm ...
CSRCS = C source file list as foo1.c foo2.c ..
4b. The Make.defs file should include a line like:
ifeq ($(CONFIG_APPNAME),y)
CONFIGURED_APPS += appname
endif
Building NuttX with Board-Specific Pieces Outside the Source Tree
-----------------------------------------------------------------
Q: Has anyone come up with a tidy way to build NuttX with board-
specific pieces outside the source tree?
A: Here are four:
1) There is a make target called 'make export'. It will build
NuttX, then bundle all of the header files, libaries, startup
objects, and other build components into a .zip file. You
can can move that .zip file into any build environment you
want. You even build NuttX under a DOS CMD window.
This make target is documented in the top level nuttx/README.txt.
2) You can replace the entire apps/ directory. If there is
nothing in the apps/ directory that you need, you can define
CONFIG_APPS_DIR in your .config file so that it points to a
different, custom application directory.
You can copy any pieces that you like from the old apps/directory
to your custom apps directory as necessary.
This is documented in NuttX/configs/README.txt and
nuttx/Documentation/NuttxPortingGuide.html (Online at
http://nuttx.sourceforge.net/NuttxPortingGuide.html#apndxconfigs
under Build options). And in the apps/README.txt file.
3) If you like the random collection of stuff in the apps/ directory
but just want to expand the existing components with your own,
external sub-directory then there is an easy way to that too:
You just create the sympolic link at apps/external that
redirects to your application sub-directory. The apps/Makefile
will always automatically check for the existence of an
apps/external directory and if it exists, it will automatically
incorporate it into the build.
This feature of the apps/Makefile is documented only here.
You can, for example, create a script called install.sh that
installs a custom application, configuration, and board specific
directory:
a) Copy 'MyBoard' directory to configs/MyBoard.
b) Add a symbolic link to MyApplication at apps/external
c) Configure NuttX (usually by:
tools/configure.sh MyBoard/MyConfiguration
or simply by copying defconfig->nutt/.config,
setenv.sh->nuttx/setenv.sh, Make.defs->nuttx/Make.defs,
appconfig->apps/.config
Using the 'external' link makes it especially easy to add a
'built-in' application an existing configuration.
4) Add any link to apps/
a) Add symbolic links apps/ to as many other directories as you
want.
b) Then just add the (relative) paths to the links in your
appconfig file (that becomes the apps/.config file).
That is basically the same as my option #3 but doesn't use the
magic 'external' link. The toplevel apps/Makefile will always
to build whatever in finds in the apps/.config file (plus the
external link if present).
