This is the README file for the port of NuttX to the MoteinoMEGA from
|
||||
LowPowerLab (http://www.lowpowerlab.com). The MoteinoMEGA is based
|
||||
on an Atmel ATMega1284P. As of this writing, documentation for the
|
||||
MoteinoMEGA board is available here:

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.
|
||||
|
||||
This port was tested using the OS X / CROSSPACK tool chain, GCC version 4.8.1.
|
||||
Please see other NuttX documentation for toolchain details.
|
||||
|
||||
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_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.
|
||||
|
||||
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.
|
||||
|
||||
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.
