First step at porting to MoteinoMEGA. LED shows assert failure at boot. Appears to be short double blink, short off (~1sec), followed by 250ms toggle cycles. Most of it derived from amber board.

DualOptiboot Bootloader
|
||||
^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
o FTDI (or similar) USB-To-Serial converter with compatible connector
|
||||
configured for DTR (AdaFruit, SparkFun, etc)
|
||||
o Obtain ard-reset-arduino Python script
|
||||
(one source: https://github.com/mikaelpatel/Cosa/blob/master/build/Arduino-Makefile/bin/ard-reset-arduino)
|
||||
This script triggers the DTR pin to enter bootloader mode.
|
||||
o Obtain avrdude for your platform.
|
||||
|
||||
Bootloader operates at 115200 baud. It would be useful to create a short script
|
||||
that invokes ard-reset-arduino and then avrdude to load program. This script
|
||||
could then also, optionally, invoke miniterm.py or some other serial interface
|
||||
program for console.
|
||||
|
||||
Example:
|
||||
|
||||
APP=nuttx
|
||||
CPU=atmega1284p
|
||||
BAUD=115200
|
||||
PORT=/dev/tty.usbserial-A703X8PQ
|
||||
avr-size --mcu=$CPU -C --format=avr $APP
|
||||
ard-reset-arduino --verbose $PORT
|
||||
avrdude -q -V -p $CPU -C {location-of-avrdude.conf} -D -c arduino -b $BAUD \
|
||||
-P $PORT -U flash:w:${APP}.hex:i
|
||||
miniterm.py --port=$PORT --baud=$BAUD -q --lf
|
||||
|
||||
Toolchains
|
||||
^^^^^^^^^^
|
||||
|
||||
The toolchain may be selected using the kconfig-mconf tool (via 'make menuconfig'),
|
||||
by editing the existing configuration file (defconfig), or by overriding
|
||||
the toolchain on the make commandline with CONFIG_AVR_TOOLCHAIN=<toolchain>.
|
||||
|
||||
The valid values for <toolchain> are BUILDROOT, CROSSPACK, LINUXGCC and WINAVR.
|
||||
|
||||
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.
|
||||
|
||||
Mac OS X:
|
||||
|
||||
For Mac OS X, the CrossPack for AVR toolchain is available from:
|
||||
|
||||
http://www.obdev.at/products/crosspack/index.html
|
||||
|
||||
This toolchain is functionally equivalent to the Linux GCC toolchain.
|
||||
|
||||
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 no 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.
|
||||
|
||||
MKDEP = $(TOPDIR)/tools/mknulldeps.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>
|
||||
|
||||
NOTE: you also must copy avr-libc header files into the NuttX include
|
||||
directory with command perhaps like:
|
||||
|
||||
cp -a /cygdrive/c/WinAVR/include/avr include/.
|
||||
|
||||
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.
|
||||

||||

Header Files
|
||||
|
||||
In any case, header files from avr-libc are required: http://www.nongnu.org/avr-libc/.
|
||||
A 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
|
||||
get avr-libc from binaries.
|
||||
|
||||
Header File Installation
|
||||
|
||||
The NuttX build will required that the AVR header files be available via
|
||||
the NuttX include directory. This can be accomplished by either copying
|
||||
the avr-libc header files into the NuttX include directory:
|
||||
|
||||
cp -a <avr-libc-path>/include/avr <nuttx-path>/include/.
|
||||
|
||||
Or simply using a symbolic link:
|
||||
|
||||
ln -s <avr-libc-path>/include/avr <nuttx-path>/include/.
|
||||
|
||||
Build Notes:
|
||||
|
||||
It may not necessary to have a built version of avr-lib; only header files
|
||||
are required. Bu if you choose to use the optimized libraru functions of
|
||||
the flowing point library, then you may have to build avr-lib from sources.
|
||||
Below are instructions for building avr-lib from fresh sources:
|
||||
|
||||
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 the following
|
||||
loction:
|
||||
|
||||
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
|
||||
|
||||
MoteinoMEGA 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_FAMILY=avr
|
||||
|
||||
CONFIG_ARCH_FAMILY_family - For use in C code:
|
||||
|
||||
CONFIG_ARCH_FAMILY_AVR=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_ATMEGA1284P=y
|
||||
|
||||
CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
|
||||
hence, the board that supports the particular chip or SoC.
|
||||
|
||||
CONFIG_ARCH_BOARD=moteino-mega
|
||||
|
||||
CONFIG_ARCH_BOARD_name - For use in C code
|
||||
|
||||
CONFIG_ARCH_BOARD_MOTEINO_MEGA=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_RAM_SIZE - Describes the installed DRAM. One of:
|
||||
|
||||
CONFIG_RAM_SIZE=(16*1024) - (16Kb)
|
||||
|
||||
CONFIG_RAM_START - The start address of installed SRAM
|
||||
|
||||
CONFIG_RAM_START=0x800100
|
||||
|
||||
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.

Common Configuration Notes
|
||||
--------------------------
|
||||
|
||||
1. Each MoteinoMEGA configuration is maintained in a sub-directory and
|
||||
can be selected as follow:
|
||||
|
||||
cd tools
|
||||
./configure.sh moteino-mega/<subdir>
|
||||
cd -
|
||||
. ./setenv.sh
|
||||
|
||||
Where <subdir> is one of the configuration sub-directories described in
|
||||
the following paragraph.
|
||||
|
||||
NOTE: You must also copy avr-libc header files, perhaps like:
|
||||
|
||||
cp -a /cygdrive/c/WinAVR/include/avr include/.
|
||||
|
||||
2. These configurations use the mconf-based configuration tool. To
|
||||
change a configurations using that tool, you should:
|
||||
|
||||
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
||||
and misc/tools/
|
||||
|
||||
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
||||
reconfiguration process.
|
||||
|
||||
3. By default, all configurations assume the NuttX Buildroot toolchain
|
||||
under Cygwin with Windows. This is easily reconfigured:
|
||||
|
||||
CONFIG_HOST_WINDOWS=y
|
||||
CONFIG_WINDOWS_CYGWIN=y
|
||||
CONFIG_AVR_BUILDROOT=y
|
||||
|
||||
Configuration Sub-Directories
|
||||
-----------------------------
|
||||
|
||||
hello:
|
||||
The simple apps/examples/hello "Hello, World!" example.
|
||||
|
||||
nsh:
|
||||
Configures the NuttShell (nsh) located at examples/nsh. The
|
||||
Configuration enables only the serial NSH interfaces.
