The documentation grew one page at a time, so the tree follows the
history of who wrote what and not the shape of NuttX. Scheduling is
spread over three places, a driver page can sit above the subsystem
that owns it, and the front page lists everything at the same level.
That is a lot to face when all you want to know is where the scheduler
lives.
This change files every page under the code it describes. It is a move,
not a rewrite: outside the ten pages named below, every page keeps the
text that is already in master, and no page's text is deleted.
What it does:
* Groups the table of contents into nine chapters.
* Moves the OS subsystems under os/: scheduling, memory, drivers,
filesystem, networking, IPC, interrupts, libs, time.
* Renames the platform pages to the names the source tree uses, and
derives their tags from the tree instead of by hand.
* Splits guides/ by subject.
* Adds Documentation/redirects.py, with a rule for every page that left
its old path, so old URLs keep working. The redirect page also carries
a link's #anchor across to the new page.
Ten pages have text that is new or rewritten. Nine of them are the
landing page of a chapter, which has to exist for the new structure:
index the front page
os/index OS Design
os/scheduling/index Scheduling
os/interrupts/index Interrupts
os/ipc/index IPC
os/time/index Time and timers
about/index About
developing/index Developing NuttX
ReleaseNotes/index Release notes
The tenth is os/libs/libbuiltin, the only page here with technical
content: libs/libbuiltin/ had no page at all. Five SVG diagrams come
with these pages, hand-written XML with no editor metadata.
Nothing outside Documentation/ is touched.
How it was checked:
* Sphinx builds with -W: no warnings, and no document left outside a
toctree.
* A script, offered in the PR, proves the narrow claim this rests on.
For every page outside the ten named above it erases what a move
touches -- link target, path, tag line, toctree block, table border --
from the whole old text and the whole new text, and requires the two
to be byte for byte identical. It also requires every sentence of a
deleted page to turn up somewhere, and every page that left its old
path to have a redirect, from a URL that existed, to where its content
went. It exits non-zero and names the page if any of that is not true,
and it tests added pages too, so forgetting to declare one cannot make
it pass.
* An independent audit checked 133 factual claims on these ten pages
against the tree, one shell command per claim: 130 confirmed, 1
refuted and fixed here, 2 not checkable.
* tools/checkpatch.sh is clean over the range.
The diff is large because moving a page changes every link that points
to it. Most of it is pure renames, and board pages that gained one tag
line.

NuttX-6.20
The 87th release of NuttX, Version 6.20, was made on July 12, 2012, and is available for download from the SourceForge website. Note that release consists of two tarballs: nuttx-6.20.tar.gz and apps-6.20.tar.gz. Both may be needed (see the top-level nuttx/README.txt file for build information).
This release corresponds with SVN release number: r4937
Additional new features and extended functionality:
-
Power Management: An evolving power management example is being created by Diego Sanchez. This effort currently involves on the STM32 F1 but clearly demonstrates the NuttX power management system which will automatically drive the system to lower power usage states due to lack of use.
-
Drivers: Added a driver for the SST 25 SPI-based FLASH parts.
-
PIC32: Added support for the PIC32MX1 and PIC32MX2 families. Added support for the microchipOpen and Pinguino toolchains.
-
NXP LPC43XX: Added support for the entire LPC43xx family
-
PIC32 boards: Added support for the DTX1-4000L "Mirtoo" module from http://www.dimitech.com/ (PIC32MX2).
-
NXP LPC43XX Boards: Added support for NGX LPC4330-Xplorer board.
-
NXP LPC17XX Boards: Added support for Micromint Lincoln60 board (LPC1769).
-
LM3S Boards: Add a configuration to support the TI/Stellaris EKK-LM3S3B96 development board. Contributed by Jose Pablo Rojas V.
-
Library: NuttX now supports platform-specific stdarg.h header files.
Work in progress. This release includes some partially completed work that is still not ready for prime time.
-
Automated Configuration. Automated configuration based on the kconfig-frontends tool is being incorporated into the build system. The configuration is still not complete enough for general use in this release.
-
STM32 Drivers. Added files that will (eventually) hold an STM32 OTG FS host driver. This is still a work in progress.
Bugfixes (see the change log for details) :
- PIC32: GPIO output configuration (critical bug)
- STM32: Typos in pin mapping files.
- LM3S: Fixed an optimization related but that caused slow start-up times if optimization was disabled.
- Library: Fixed signed extension but in all limit.h files (reported by Lorenz Meier). inet_ntoa compilation failure on Z80.
As well as other, less critical bugs (see the ChangeLog for details)
