README
^^^^^
This is the README file for the port of NuttX to the Amber Web Server from
SoC Robotics (http://www.soc-robotics.com/index.htm). The
Amber Web Server is based on an Atmel ATMega128. As of this writing,
documentation for the Amber Web Server board is available here:
http://www.soc-robotics.com/product/Amber_Specs/Amber_Processor.html
and

Amber Web Server Features
^^^^^^^^^^^^^^^^^^^^^^^^^
Toolchains
^^^^^^^^^^
Buildroot:
There is a DIY buildroot version for the AVR boards here:
http://sourceforge.net/projects/nuttx/files/buildroot/. See the
following section for details on building this toolchain.
It is assumed in some places that buildroot toolchain is available
at ../misc/buildroot/build_avr. Edit the setenv.sh file if
this is not the case.
After configuring NuttX, make sure that CONFIG_AVR_BUILDROOT=y is set in your
.config file.
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. Edit the
setenv.sh file if this is not the case.
After configuring NuttX, make sure that CONFIG_AVR_WINAVR=y is set in your
.config file.
WARNING: There is an incompatible version of cygwin.dll in the WinAVR/bin
directory! Make sure that the path to the correct cygwin.dll file precedes
the path to the WinAVR binaries!
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
An additional issue with the WinAVR toolchain, in particular, is that it
contains an incompatible version of the Cygwin DLL in its bin/ directory.
You must take care that the correct Cygwin DLL is used.
NuttX buildroot Toolchain
^^^^^^^^^^^^^^^^^^^^^^^^^
If NuttX buildroot toolchain source tarball cne can be downloaded from the
NuttX SourceForge download site (https://sourceforge.net/projects/nuttx/files/).
This GNU toolchain builds and executes in the Linux or Cygwin environment.
1. You must have already configured Nuttx in <some-dir>/nuttx.
cd tools
./configure.sh amber/<sub-dir>
2. Download the latest buildroot package into <some-dir>
3. unpack the buildroot tarball. The resulting directory may
have versioning information on it like buildroot-x.y.z. If so,
rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
4. cd <some-dir>/buildroot
5. cp configs/avr-defconfig-4.5.2 .config
6. make oldconfig
7. make
8. Edit setenv.h, if necessary, so that the PATH variable includes
the path to the newly built binaries.
See the file configs/README.txt in the buildroot source tree. That has more
detailed PLUS some special instructions that you will need to follow if you
are building a toolchain for Cygwin under Windows.
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). But if you are using
the NuttX buildroot configuration on Cygwin, then you will have to build
avr-libc from binaries.
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"}
Amber Web Server Configuration Options
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
CONFIG_ARCH - Identifies the arch/ subdirectory. This should
be set to:
CONFIG_ARCH=avr
CONFIG_ARCH_family - For use in C code:
CONFIG_ARCH_AVR=y
CONFIG_ARCH_architecture - For use in C code:
CONFIG_ARCH_ATMEGA=y
CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
CONFIG_ARCH_CHIP=atmega
CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
chip:
CONFIG_ARCH_CHIP_ATMEGA128=y
CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
hence, the board that supports the particular chip or SoC.
CONFIG_ARCH_BOARD=amber
CONFIG_ARCH_BOARD_name - For use in C code
CONFIG_ARCH_BOARD_AMBER=y
CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
of delay loops
CONFIG_ENDIAN_BIG - define if big endian (default is little
endian)
CONFIG_DRAM_SIZE - Describes the installed DRAM. One of:
CONFIG_DRAM_SIZE=(8*1024) - (8Kb)
CONFIG_DRAM_START - The start address of installed DRAM
CONFIG_DRAM_START=0x10000000
CONFIG_DRAM_END - Last address+1 of installed RAM
CONFIG_DRAM_END=(CONFIG_DRAM_START+CONFIG_DRAM_SIZE)
CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
have LEDs
CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
stack. If defined, this symbol is the size of the interrupt
stack in bytes. If not defined, the user task stacks will be
used during interrupt handling.
CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to board architecture.
CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
cause a 100 second delay during boot-up. This 100 second delay
serves no purpose other than it allows you to calibratre
CONFIG_ARCH_LOOPSPERMSEC. You simply use a stop watch to measure
the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
the delay actually is 100 seconds.

CONFIG_AVR_TWI=n
ATMEGA specific device driver settings
CONFIG_UARTn_SERIAL_CONSOLE - selects the UARTn for the
console and ttys0 (default is the UART0).
CONFIG_UARTn_RXBUFSIZE - Characters are buffered as received.
This specific the size of the receive buffer
CONFIG_UARTn_TXBUFSIZE - Characters are buffered before
being sent. This specific the size of the transmit buffer
CONFIG_UARTn_BAUD - The configure BAUD of the UART. Must be
CONFIG_UARTn_BITS - The number of bits. Must be either 7 or 8.

be selected as follow:
cd tools
./configure.sh amber/<subdir>
cd -
. ./setenv.sh
Where <subdir> is one of the following:
ostest:
