*
* LED GPIO
* ---------------- -----
* L Amber LED PB27
* TX Yellow LED PA21
* RX Yellow LED PC30
*
* LED L is connected to ground and can be illuminated by driving the PB27

* driving the corresponding
* GPIO output to low.
*
* These LEDs are not used by the board port unless CONFIG_ARCH_LEDS is

* LED_ASSERTION An assertion failed N/C GLOW OFF

/* There are three user-controllable LEDs on board the Arduino Due board:
*
* LED GPIO
* ---------------- -----
* L Amber LED PB27
* TX Yellow LED PA21
* RX Yellow LED PC30
*
* LED L is connected to ground and can be illuminated by driving the PB27
* output high. The TX and RX LEDs are pulled high and can be illuminated by
* driving the corresponding
* GPIO output to low.
*
* These LEDs are not used by the board port unless CONFIG_ARCH_LEDS is
* defined. In that case, the usage by the board port is defined in
* include/board.h and src/sam_leds.c. The LEDs are used to encode OS-related
* events as follows:
*
* SYMBOL MEANING LED STATE
* L TX RX
* ------------------- ----------------------- -------- -------- --------
* LED_STARTED NuttX has been started OFF OFF OFF
* LED_HEAPALLOCATE Heap has been allocated OFF OFF OFF
* LED_IRQSENABLED Interrupts enabled OFF OFF OFF
* LED_STACKCREATED Idle stack created ON OFF OFF
* LED_INIRQ In an interrupt N/C GLOW OFF
* LED_SIGNAL In a signal handler N/C GLOW OFF
* LED_ASSERTION An assertion failed N/C GLOW OFF
* LED_PANIC The system has crashed N/C N/C Blinking
* LED_IDLE MCU is is sleep mode ------ Not used --------
*
* Thus if LED L is statically on, NuttX has successfully booted and is,
* apparently, running normmally. If LED RX is glowing, then NuttX is
* handling interrupts (and also signals and assertions). If TX is flashing

README
======
This is the README file for the port of NuttX to the Arduino Mega 2560 Rev3.
https://www.arduino.cc/en/Main/ArduinoBoardMega2560
The board is based on ATMega2560 chip from Atmel
http://www.atmel.com/devices/atmega2560.aspx
Contents
========
o Toolchain
o Serial Console
o Configurations
Toolchain
=========
Right now only Atmel's AVR8 Toolchain is supported. You can get it from
http://www.atmel.com/tools/atmelavrtoolchainforwindows.aspx
It is basically WinAVR compatible so sub-projects may define WinAVR as a
tool-chain but specify path to the Atmel AVR8 in path. See
arduino-mega2560/hello for example.
Serial Console
==============
The serial console is available on USART0. You will need to connect an
RS-232 shield or an external RS-232 driver as follows:
TXD: TX0->1
RXD: RX0->0
GND: Power GND
+5V: Power +5V
You will then need to use a terminal program configured at 38400 8N1.
Configurations
==============
Common Configuration Notes
--------------------------
1. Each Arduino MEGA2560 configuration is maintained in a sub-directory
and can be selected as follow:
cd tools
./configure.sh arduino-mega2560/<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
see additional README.txt files in the NuttX tools repository.
b. Execute 'make menuconfig' in nuttx/ in order to start the
reconfiguration process.
3. By default, all configurations assume the Atmel Studio AVR8 toolchain
under Cygwin with Windows. This is easily reconfigured:
CONFIG_HOST_WINDOWS=y
CONFIG_WINDOWS_CYGWIN=y
CONFIG_AVR_BUILDROOT_TOOLCHAIN=y
Configuration Sub-Directories
-----------------------------
hello:
The simple apps/examples/hello "Hello, World!" example.
nsh:
This is a reduce NuttShell (NSH) configuration using apps/example/nsh.
The serial console is provided on USART0 and can be accessed via
an external RS-232 driver as described above under "Serial Console".
NOTES:
1. As of 2015-01-16, the default static memory usage is:
$ size nuttx.elf
text data bss dec hex filename
34348 2117 944 37409 9221 nuttx.elf
And dynamic, heap usage:
nsh> free
total used free largest
Mem: 4736 1768 2968 2968
There is plenty of FLASH space but not a lot of free SRAM. This
SRAM usage is due primarily to constant strings defined by NSH.
NOTE: I investigated the possibility of adding IPTR/IOBJ
qualifiers in the NSH library and moving the strings to FLASH.
This is still a possibility but would requires some extensive
changes to NSH.

GPIO Pin Configuration
^^^^^^^^^^^^^^^^^^^^^^
The only GPIO pin usage is for LEDs (2) and Buttons (2):
PIN 13 PA7 LED1
PIN 14 PA8 LED2
PIN 24 PB2 KEY1
PIN 25 PB3 KEY2
(See configs/avr32dev1/src/avr32dev1.h). And also for
crystals (4), JTAG (1), and USB (1):
PIN 30 PA11 XIN32
PIN 31 PA12 XOUT32
PIN 35 PA15 EVTO (JTAG)
PIN 39 PA18 X1IN
PIN 40 PA19 X1OUT
PIN 61 PA26 ID (USB)
All GPIO pins are brought out through connectors J1 (PINS 33-64)
and J2 (PINS 1-32).
NOTE: There seems to be some difference in labeling for OSC0 and
OSC1 between MCUZone.com and Atmel:
Oscillator pinout
-------------------------- --------------------
QFP48 QFP64 Pad Oscillator AVR32DEV1
PIN PIN PIN LABEL
----- ----- ---- --------- --------------------
30 39 PA18 XIN0 X1IN (12MHz)
41 PA28 XIN1 PA28 (no crystal)
22 30 PA11 XIN32 XIN32 (32KHz)
31 40 PA19 XOUT0 X1OUT (12Mhz)
42 PA29 XOUT1 PA29 (no crystal)
23 31 PA12 XOUT32 XOUT32 (32 Khz)
----- ----- ---- --------- --------------------
NOTE 1: These crystal inputs/outputs are analog signals and my
assumption is that they need no pin multiplexing setting to
enable them for the external crystal function.
NOTE 2: There is no support for OSC1.
NOTE 3: There are solder pads for the 32KHz OSC32, but the
crystal is not populated on my board. Therefore, the RTC will
have to run from the (uncalibrated) RCOSC.
Serial Connection
^^^^^^^^^^^^^^^^^
USART1 is the default USART1 used in the configuration files to
provide a serial console (of course, that can be easily changed
by editting the configuration file). The AVR32DEV1 board has no
RS-232 drivers or connectors on board. I use an off-board MAX232
module that I got on eBay (search for MAX232 if you want to find
one). I connect the MAX232 board as follows:
In configs/avr32dev/include/board.h:
#define PINMUX_USART1_RXD PINMUX_USART1_RXD_1
#define PINMUX_USART1_TXD PINMUX_USART1_TXD_1
In arch/avr/src/at32uc3/at32uc3b_pinmux.h:
#define PINMUX_USART1_RXD_1 (GPIO_PERIPH | GPIO_FUNCD | GPIO_PORTA | 17)
#define PINMUX_USART1_TXD_1 (GPIO_PERIPH | GPIO_FUNCA | GPIO_PORTA | 23)
PA17 and PA23 are avaiable from the AVR32DEV1:
FUNC GPIO PIN Header 16X2 (J1) MX232 Board
---- ----- ----- ---------------- ------------
RXD PA17 PIN37 Pin 5 PIN4 RXD (5V TTL/CMOS)
TXD PA23 PIN47 Pin 15 PIN3 TXD (5V TTL/CMOS)
PIN2 GND
PIN1 VCC (5V)
Voltage on GPIO Pins with respect to Ground for TCK, RESET_N, PA03-PA08,
PA11-PA12, PA18-PA19, PA28-PA31............................-0.3 to 3.6V
Other Pins ............................................... -0.3 to 5.5V
I get the 5V from another USB port (using the 5V power cable that normally
provides the extra current needed by my USB IDE drive).
Development Environment
^^^^^^^^^^^^^^^^^^^^^^^
Linux, Mac OS X or Cygwin on Windows can be used for the development environment.
The source has been built only using the GNU toolchain (see below). Other
toolchains will likely cause problems. Testing was performed using the Cygwin
environment.
GNU Toolchains
^^^^^^^^^^^^^^
Atmel Toolchain:
The build logic in these directories assume that you are using the GNU
toolchain with the Atmel patches. The patch file, pre-patched tool
sources,and pre-built binaries are available from the Atmel website.
CONFIG_AVR32_AVRTOOLSW=y # Use the windows version
CONFIG_AVR32_AVRTOOLSL=y # Ue the Linux version
NOTE: The NuttX builtroot cannot be used to build the AVR32 toolchain.
This is because the Atmel patches that add support for the AVR32 are not
included in the NuttX buildroot.
WinAVR:
Another option for use under Windows is WinAVR:
http://sourceforge.net/projects/winavr/files/. WinAVR includes the
AVR32 toolchain as well as the AVR toolchain and various support
libraries and header files.
AVR32 Toolchain Builder:
A third option is to build the toolchain yourself. For OS X and Linux systems,
this Makefile will build a complete gcc-4.4.3 toolchain:
https://github.com/jsnyder/avr32-toolchain
By default the toolchain installs into ${HOME}/avr-32-tools-<somedate> and
the bin subdirectory must be added to your path before compiling.
IDEs
^^^^
NuttX is built using command-line make. It can be used with an IDE, but some
effort will be required to create the project.
Makefile Build
--------------
Under Eclipse, it is pretty easy to set up an "empty makefile project" and
simply use the NuttX makefile to build the system. That is almost for free
under Linux. Under Windows, you will need to set up the "Cygwin GCC" empty
makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
there is a lot of help on the internet).
Native Build
------------
Here are a few tips before you start that effort:
1) Select the toolchain that you will be using in your .config file
2) Start the NuttX build at least one time from the Cygwin command line
before trying to create your project. This is necessary to create
certain auto-generated files and directories that will be needed.
3) Set up include pathes: You will need include/, arch/avr/src/at32uc3,
arch/avr/src/common, arch/arm/src/avr, and sched/.
4) All assembly files need to have the definition option -D __ASSEMBLY__
on the command line.
Startup files will probably cause you some headaches. The NuttX startup file
is arch/avr/src/avr3/up_nommuhead.S.
AVR32 Bootloader
^^^^^^^^^^^^^^^^
Boot Sequence
-------------
"An AVR UC3 part having the bootloader programmed resets as any other
part at 80000000h. Bootloader execution begins here. The bootloader
first performs the boot process to know whether it should start the
USB DFU ISP or the application. If the tested conditions indicate
that the USB DFU ISP should be started, then execution continues in
the bootloader area, i.e. between 80000000h and 80002000h, else
the bootloader launches the application at 80002000h."
Link Address
------------
The linker scripts (ld.script) assume that you are using the DFU
bootloader. The bootloader resides at 0x8000:0000 and so the ld.script
files link the application to execute after the bootloader at
0x8000:2000. To link so that NuttX boots directly without using the
bootloader, change the flash definition from:
flash (rxai!w) : ORIGIN = 0x80002000, LENGTH = 256K - 8K
to:
flash (rxai!w) : ORIGIN = 0x80000000, LENGTH = 256K
Or to use the MSC bootloader:
flash (rxai!w) : ORIGIN = 0x80008000, LENGTH = 256K - 32K
Entering the ISP
----------------
In order to use the USB port to download the FLASH(ISP), you need to
use the S3(PA13) to make CPU return to boot status. In this mode, the
on chip bootloader will run, making the ISP possible.
BatchISP
--------
Unlike other Atmel parts, the AVR32 will not work with the FLIP GUI
program. Instead, you must use the command-line loader call BatchISP.
If need to download FLIP from the atmel.com website, install the USB
driver in the FLIP usb directory. Then in the bin directory where
you installed FLIP, you will also find batchisp.exe.
NOTE: The AVR32DEV1 setenv.sh files will add the path to the BatchISP
bin directory to the Cygwin PATH variable. If you use a different
version of FLIP or if you install FLIP in a different location, you
will need to modify the setenv.sh files.
Notes from "AVR32 UC3 USB DFU Bootloader" (doc7745.pdf)
"To launch BatchISP, open a command prompt. Windows or Cygwin command
prompt can be used provided that the bin folder of the FLIP installation
directory is in the PATH (Windows’ or Cygwin’s) environment variable.
When running BatchISP on AT32UC3xxxxx, the target part has to be specified
with -device at32uc3xxxxx and the communication port with -hardware usb.
Commands can then be placed after -operation. These commands are executed
in order. BatchISP options can be placed in a text file invoked using
-cmdfile rather than on the command line.
"BatchISP works with an internal ISP buffer per target memory. These ISP
buffers can be filled from several sources. All target operations (program,
verify, read) are performed using these buffers."
The following BatchISP command line will erase FLASH, write the nuttx binary
into FLASH, and reset the AVR32. This command line is available in the
script config/avr32dev1/tools/doisp.sh:
batchisp -device at32uc3b0256 -hardware usb -operation erase f memory flash \
blankcheck loadbuffer nuttx.elf program verify start reset 0
"BatchISP main commands available on AT32UC3xxxxx are:
- ASSERT { PASS | FAIL } changes the displayed results of the following
operations according to the expected behavior.
- ONFAIL { ASK | ABORT | RETRY | IGNORE } changes the interactive behavior
of BatchISP in case of failure.
- WAIT <Nsec> inserts a pause between two ISP operations.
- ECHO <comment> displays a message.
- ERASE F erases internal flash contents, except the bootloader.
- MEMORY { FLASH | SECURITY | CONFIGURATION | BOOTLOADER | SIGNATURE | USER }
selects a target memory on which to apply the following operations.
- ADDRANGE <addrMin> <addrMax> selects in the current target memory an
address range on which to apply the following operations.
- BLANKCHECK checks that the selected address range is erased.
- FILLBUFFER <data> fills the ISP buffer with a byte value.
- LOADBUFFER { <in_elffile> | <in_hexfile> } loads the ISP buffer from an
input file.
- PROGRAM programs the selected address range with the ISP buffer.
- VERIFY verifies that the selected address range has the same contents
as the ISP buffer.
- READ reads the selected address range to the ISP buffer.
- SAVEBUFFER <out_hexfile> { HEX386 | HEX86 } saves the ISP buffer to an
output file.
- START { RESET | NORESET } 0 starts the execution of the programmed
application with an optional hardware reset of the target.
"The AT32UC3xxxxx memories made available by BatchISP are:
- FLASH: This memory is the internal flash array of the target, including the
bootloader protected area. E.g. on AT32UC3A0512 (512-kB internal flash),
addresses from 0 to 0x7FFFF can be accessed in this memory.
- SECURITY: This memory contains only one byte. The least significant bit
of this byte reflects the value of the target Security bit which can only
be set to 1. Once set, the only accepted commands will be ERASE and START.
After an ERASE command, all commands are accepted until the end of the
non-volatile ISP session, even if the Security bit is set.
- CONFIGURATION: This memory contains one byte per target general-purpose
fuse bit. The least significant bit of each byte reflects the value of
the corresponding GP fuse bit.
- BOOTLOADER: This memory contains three bytes concerning the ISP: the ISP
version in BCD format without the major version number (always 1), the
ISP ID0 and the ISP ID1.
- SIGNATURE: This memory contains four bytes concerning the part: the product
manufacturer ID, the product family ID, the product ID and the product
revision.
- USER: This memory is the internal flash User page of the target, with
addresses from 0 to 0x1FF.
"For further details about BatchISP commands, launch batchisp -h or see the
help files installed with FLIP ..."
Reset
^^^^^
I don't trust the reset button -- if you reset and something weird happens,
try a full power cycle.
Make Tip
^^^^^^^^
Because this build uses a native Windows toolchain and the native Windows
tools do not understand Cygwin's symbolic links, the NuttX make system does
something weird: It copies the configuration directories instead of linking
to them (it could, perhaps, use the NTFS 'mklink' command, but it doesn't).
A consequence of this is that you can easily get confused when you edit
a file in one of the "linked" directories, re-build NuttX, and then not see your
changes when you run the program. That is because build is still using the
version of the file in the copied directory, not your modified file! To work
around this annoying behavior, do the following when you re-build:
make clean_context all <-- Remove and re-copy all of the directories, then make all
doisp.sh <-- Load the code onto the board.
AVR32DEV1 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_FAMILY_AVR32=y
CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
CONFIG_ARCH_CHIP=at32uc3
CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
chip:
CONFIG_ARCH_CHIP_AT32UC3B0256
CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
hence, the board that supports the particular chip or SoC.
CONFIG_ARCH_BOARD=avr32dev1 (for the AV32DEV1 board)
CONFIG_ARCH_BOARD_name - For use in C code
CONFIG_ARCH_BOARD_AVR32DEV1
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 (SRAM in this case):
CONFIG_RAM_SIZE=0x00010000 (64Kb)
CONFIG_RAM_START - The start address of installed DRAM
CONFIG_RAM_START=0x20000000
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.
Individual subsystems can be enabled:
CONFIG_AVR32_GPIOIRQ - GPIO interrupt support
CONFIG_AVR32_GPIOIRQSETA - Set of GPIOs on PORTA that support interrupts
CONFIG_AVR32_GPIOIRQSETB - Set of GPIOs on PORTB that support interrupts
CONFIG_AVR32_USARTn - Enable support for USARTn
CONFIG_AVR32_USARTn_RS232 - Configure USARTn as an RS232 interface.
CONFIG_AVR32_USARTn_SPI - Configure USARTn as an SPI interface.
CONFIG_AVR32_USARTn_RS485 - Configure USARTn as an RS485 interface.
CONFIG_AVR32_USARTn_MAN - Configure USARTn as an Manchester interface.
CONFIG_AVR32_USARTn_MODEM - Configure USARTn as an Modem interface.
CONFIG_AVR32_USARTn_IRDA - Configure USARTn as an IRDA interface.
CONFIG_AVR32_USARTn_ISO786 - Configure USARTn as an ISO786 interface.
AT32UC3B0256 specific device driver settings
CONFIG_USARTn_SERIAL_CONSOLE - selects the USARTn for the
console and ttys0 (default is the USART0).
CONFIG_USARTn_RXBUFSIZE - Characters are buffered as received.
This specific the size of the receive buffer
CONFIG_USARTn_TXBUFSIZE - Characters are buffered before
being sent. This specific the size of the transmit buffer
CONFIG_USARTn_BAUD - The configure BAUD of the USART. Must be
CONFIG_USARTn_BITS - The number of bits. Must be either 7 or 8.
CONFIG_USARTn_PARTIY - 0=no parity, 1=odd parity, 2=even parity
CONFIG_USARTn_2STOP - Two stop bits
Configurations
^^^^^^^^^^^^^^
Common Configuration Notes
--------------------------
1. Each Atmel AVR32DEV configuration is maintained in a sub-directory and
can be selected as follow:
cd tools
./configure.sh avr32dev1/<subdir>
cd -
. ./setenv.sh
Where <subdir> is one of the configuration sub-directories described in
the following paragraph.
(Use configure.bat instead of configure.sh in a native Windows environment).
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
see additional README.txt files in the NuttX tools repository.
b. Execute 'make menuconfig' in nuttx/ in order to start the
reconfiguration process.
3. By default, all configurations assume the AVR toolchain under Cygwin
with Windows. This is easily reconfigured:
CONFIG_HOST_WINDOWS=y
CONFIG_WINDOWS_CYGWIN=y
CONFIG_AVR32_AVRTOOLSW=y
Configuration Sub-Directories
-----------------------------
nsh:
Configures the NuttShell (nsh) located at examples/nsh. The
Configuration enables only the serial NSH interface.
ostest:
This configuration directory, performs a simple OS test using
examples/ostest.
NOTE: Round-robin scheduling is disabled in this test because
the RR test in examples/ostest declares data structures that
are too large for the poor little uc3 SRAM.
