+README
+^^^^^
+
+This is the README file for the port of NuttX to the Micropendous 3 board.
+This board is develepmend by http://code.google.com/p/opendous/. The
+Micropendous 3 is based on an Atmel AT90USB646, 647, 1286 or 1287 MCU.
+NuttX was ported using the AT90USB647 version. As of this writing,
+documentation for the Micropendous board is available here:
+http://code.google.com/p/micropendous/wiki/Micropendous3
+
+Micropendous 3 Features
+^^^^^^^^^^^^^^^^^^^^^^^
+
+ o Based on the 64-pin USB AVR Microcontrollers: AT90USB646, AT90USB647,
+ AT90USB1286, or AT90USB1287.
+ o USB Full Speed (12Mbit/s)
+ o USB Device Mode (Host mode supported with AT90USBxx7 devices)
+ o 60kb (AT90USB64) or 120kb (AT90USB128) of available FLASH memory for
+ your programs (4kb(AT90USB64)/8kb(AT90USB128) used by USB bootloader -
+ stock Atmel or LUFA)
+ o 4 kbytes SRAM and 2 kbytes of EEPROM (AT90USB64) or 8 kbytes SRAM and 4
+ kbytes of EEPROM (AT90USB128)
+ o external SRAM is possible
+ o USB powered
+ o 16MHz crystal
+ o 48 General Purpose IO Pins (47 with external SRAM)
+ o Vcc=VBUS jumper selects whether USB VBUS or an external supply is used
+ to power the board
+ o RESET and HWB buttons to enable firmware loading over USB (no external
+ programmer required)
+ o HWB can be used as a user button
+ o USB-A Plug
+ o JTAG header
+ o Size LxWxH (including headers): 3.15" x 0.8" x 0.6" =~ 8cm x 2cm x 1.5cm
+ o Completely OpenHardware Design
+
+Contents
+^^^^^^^^
+
+ o Toolchains
+ o Windows Native Toolchains
+ o avr-libc
+
+Toolchains
+^^^^^^^^^^
+
+Buildroot:
+
+ There is a buildroot version for the AVR boards here:
+ http://sourceforge.net/projects/nuttx/files/buildroot/. However, that
+ toolchain cannot be recommended at this time because it lacks certain
+ important patches.
+
+WinAVR:
+
+ For Cygwin development environment on Windows machines, you can use
+ WinAVR: http://sourceforge.net/projects/winavr/files/
+
+ It is assumed in some places that WinAVR is installed at C:/WinAVR.
+
+ After configuring NuttX, make sure that CONFIG_AVR_WINAVR=y is set in your
+ .config file.
+
+Linux:
+
+ For Linux, there are widely available avr-gcc packages. On Ubuntu, use:
+ sudo apt-get install gcc-avr gdb-avr avr-libc
+
+ After configuring NuttX, make sure that CONFIG_AVR_LINUXGCC=y is set in your
+ .config file.
+
+Windows Native Toolchains
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+ The WinAVR toolchain is a Windows native toolchain. There are several
+ limitations to using a Windows native toolchain in a Cygwin environment.
+ The three biggest are:
+
+ 1. The Windows toolchain cannot follow Cygwin paths. Path conversions are
+ performed automatically in the Cygwin makefiles using the 'cygpath'
+ utility but you might easily find some new path problems. If so, check
+ out 'cygpath -w'
+
+ 2. Windows toolchains cannot follow Cygwin symbolic links. Many symbolic
+ links are used in Nuttx (e.g., include/arch). The make system works
+ around these problems for the Windows tools by copying directories
+ instead of linking them. But this can also cause some confusion for
+ you: For example, you may edit a file in a "linked" directory and find
+ that your changes had not effect. That is because you are building the
+ copy of the file in the "fake" symbolic directory. If you use a
+ Windows toolchain, you should get in the habit of making like this:
+
+ make clean_context all
+
+ An alias in your .bashrc file might make that less painful.
+
+ 3. Dependencies are not made when using Windows versions of the GCC. This
+ is because the dependencies are generated using Windows pathes which do
+ not work with the Cygwin make.
+
+ Support has been added for making dependencies with the windows-native
+ toolchains. That support can be enabled by modifying your Make.defs
+ file as follows:
+
+ - MKDEP = $(TOPDIR)/tools/mknulldeps.sh
+ + MKDEP = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+ If you have problems with the dependency build (for example, if you are
+ not building on C:), then you may need to modify tools/mkdeps.sh
+
+avr-libc
+^^^^^^^^
+
+Build Notes:
+
+ In any case, avr-libc is required. http://www.nongnu.org/avr-libc/.
+ An snapshot of avr-lib is included in the WinAVR installation. For Linux
+ development platforms, avr-libc package is readily available (and would
+ be installed in the apt-get command shown above).
+
+ Below are instructions for building avr-lib from fresh sources (I started
+ this before I realized at tha avr-lib is included in the WinAVR install):
+
+ 1. Download the avr-libc package from:
+
+ http://savannah.nongnu.org/projects/avr-libc/
+
+ I am using avr-lib-1.7.1.tar.bz2
+
+ 2. Upack the tarball and cd into the
+
+ tar jxf avr-lib-1.7.1.tar.bz2
+ cd avr-lib-1.7.1
+
+ 3. Configure avr-lib. Assuming that WinAVR is installed at
+
+ export PATH=/cygdrive/c/WinAVR/bin:$PATH
+ ./configure --build=`./config.guess` --host=avr
+
+ This takes a *long* time.
+
+ 4. Make avr-lib.
+
+ make
+
+ This also takes a long time because it generates variants for nearly
+ all AVR chips.
+
+ 5. Install avr-lib.
+
+ make install
+
+Include Path:
+
+ After configuration, the Make.def file installed in the top-level NuttX
+ directory will need to be modified to include the path to the where ever
+ the include/avr directory was installed (no other avr-libc header files
+ are needed). For, for example, if WinAVR is installed at C:/WinAVR, the
+ AVR header files will be at C:/WinAVR/avr/include/avr
+
+ AVRLIBC_INCPATH=${cygpath -u "C:/WinAVR/avr/include/avr"}

+# CONFIG_SCHED_WORKQUEUE. Create a dedicated "worker" thread to
+# handle delayed processing from interrupt handlers. This feature

+# can be safely disabled. The worker thread also performs
+# garbage collection -- completing any delayed memory deallocations
+# from interrupt handlers. If the worker thread is disabled,
+# then that clean will be performed by the IDLE thread instead
+# (which runs at the lowest of priority and may not be appropriate
+# if memory reclamation is of high priority). If CONFIG_SCHED_WORKQUEUE
