README
|
||||
======
|
||||
|
||||
This README discusses issues unique to NuttX configurations for the
|
||||
Mikroe Flip&Click STM32X board. This board is an Arduino-Due work-alike
|
||||
with four Mikroe Click bus interfaces. Like the Arduino DUE, this board
|
||||
features the Atmel ATSAM3X8E MCU running at 84 MHz.

|
||||
Buttons and LEDs
|
||||
================
|
||||
|
||||
Buttons
|
||||
-------
|
||||
There are no buttons on the Arduino Due board.
|
||||
|
||||
LEDs
|
||||
----
|
||||
There are four LEDs on the top, blue side of the board. Only
|
||||
one can be controlled by software:
|
||||
|
||||
LED L - PB27 (PWM13)
|
||||
|
||||
There are also four LEDs on the back, white side of the board:
|
||||
|
||||
LED A - PC6
|
||||
LED B - PC5
|
||||
LED C - PC7
|
||||
LED D - PC8
|
||||
|
||||
A high output value illuminates the LEDs.
|
||||
|
||||
These LEDs are available to the application and are all available to the
|
||||
application unless CONFIG_ARCH_LEDS is defined. In that case, the usage
|
||||
by the board port is defined in include/board.h and src/sam_autoleds.c.
|
||||
The LEDs are used to encode OS-related events as follows:
|
||||
|
||||
SYMBOL MEANING LED STATE
|
||||
L A B C D
|
||||
---------------- ----------------------- --- --- --- --- ---
|
||||
LED_STARTED NuttX has been started OFF ON OFF OFF OFF
|
||||
LED_HEAPALLOCATE Heap has been allocated OFF OFF ON OFF OFF
|
||||
LED_IRQSENABLED Interrupts enabled OFF OFF OFF ON OFF
|
||||
LED_STACKCREATED Idle stack created OFF OFF OFF OFF ON
|
||||
LED_INIRQ In an interrupt GLO N/C N/C N/C N/C
|
||||
LED_SIGNAL In a signal handler GLO N/C N/C N/C N/C
|
||||
LED_ASSERTION An assertion failed GLO N/C N/C N/C N/C
|
||||
LED_PANIC The system has crashed 2Hz N/C N/C N/C N/C
|
||||
LED_IDLE MCU is is sleep mode ---- Not used -----
|
||||
|
||||
Thus if LED L is glowing on and all other LEDs are off (except LED D which
|
||||
was left on but is no longer controlled by NuttX and so may be in any
|
||||
state), NuttX has successfully booted and is, apparently, running normally
|
||||
and taking interrupts. If any of LEDs A-D are statically set, then NuttX
|
||||
failed to boot and the LED indicates the initialization phase where the
|
||||
failure occurred. If LED L is flashing at approximately 2Hz, then a fatal
|
||||
error has been detected and the system has halted.
|
||||
|
||||
NOTE: After booting, LEDs A-D are no longer used by the system and may
|
||||
be controlled the application.
|
||||
|
||||
Serial Consoles
|
||||
===============
|
||||
|
||||
The SAM3X has a UART and 4 USARTS. The Programming port uses a USB-to-
|
||||
serial chip connected to the first of the MCU (RX0 and TX0 on PA8 and PA9,
|
||||
respectively). The output from that port is visible using the Arduino tool.
|
||||
|
||||
Any of UART and USART0-3 may be used as a serial console. By default,
|
||||
UART0 is used as the serial console in all configurations. But that is
|
||||
easily changed by modifying the configuration as described under
|
||||
"Configurations" below.
|
||||
|
||||
Other convenient U[S]ARTs that may be used as the Serial console include:
|
||||
|
||||
1) An Arduino Serial Shield. The RX and TX pins are available on the
|
||||
Arduino connector D0 and D1 pins, respectively. These are connected
|
||||
to USART0, RXD0 and TXD0 which are PA10 and PA11, respectively.
|
||||
|
||||
2) Mikroe Click Serial Shield. There are four Click bus connectors with
|
||||
serial ports available as follows:
|
||||
|
||||
Click A: USART0 RXD0 and TXD0 which are, again, PD10 and PD11.
|
||||
Click B: USART1 RXD1 and TXD1 which are PA12 and PA13, respectively.
|
||||
Click C: USART3 RXD3 and TXD3 which are PD5 and PD4, respectively.
|
||||
Click D: USART3 RXD3 and TXD3 which are, again, PD5 and PD4.
|
||||
|
||||
Other serial ports are probably available on the Arduino connector. I
|
||||
will leave that as an exercise for the interested reader.
|
||||
|
||||
The outputs from these pins is 3.3V. You will need to connect RS232
|
||||
transceiver to get the signals to RS232 levels (or connect to the
|
||||
USB virtual COM port in the case of UART0).
|
||||
|
||||
Loading Code
|
||||
============
|
||||
|
||||
Installing the Arduino USB Driver under Windows:
|
||||
------------------------------------------------
|
||||
1. Download the Windows version of the Arduino software, not the 1.0.x
|
||||
release but the latest 1.5.x that supports the Due. When the download
|
||||
finishes, unzip the downloaded file.
|
||||
2. Connect the Due to your computer with a USB cable via the Programming port.
|
||||
3. The Windows driver installation should fail.
|
||||
4. Open the Device Manger
|
||||
5. Look for the listing named "Ports (COM & LPT)". You should see an open
|
||||
port named "Arduino Due Prog. Port".
|
||||
6 Select the "Browse my computer for Driver software" option.
|
||||
7. Right click on the "Arduino Due Prog. Port" and choose "Update Driver
|
||||
Software".
|
||||
8. Navigate to the folder with the Arduino IDE you downloaded and unzipped
|
||||
earlier. Locate and select the "Drivers" folder in the main Arduino folder
|
||||
(not the "FTDI USB Drivers" sub-directory).
|
||||
|
||||
Uploading NuttX to the Due Using Bossa:
|
||||
---------------------------------------
|
||||
I don't think this can be done because the Arduino software is so dedicated
|
||||
to "sketches". However, Arduino uses BOSSA under the hood to load code and
|
||||
you can use BOSSA outside of Arduino.
|
||||
|
||||
Uploading NuttX to the Due Using Bossa:
|
||||
---------------------------------------
|
||||
Where do you get it?
|
||||
Generic BOSSA installation files are available here:
|
||||
http://sourceforge.net/projects/b-o-s-s-a/?source=dlp
|
||||
|
||||
However, DUE uses a patched version of BOSSA available as source code here:
|
||||
https://github.com/shumatech/BOSSA/tree/arduino
|
||||
|
||||
But, fortunately, since you already installed Arduino, you already have
|
||||
BOSSA installed. In my installation, it is here:
|
||||
|
||||
C:\Program Files (x86)\Arduino\arduino-1.5.2\hardware\tools\bossac.exe
|
||||
|
||||
General Procedure
|
||||
-----------------
|
||||
|
||||
1) Erase the FLASH and put the Due in bootloader mode
|
||||
2) Write the file to FLASH
|
||||
3) Configure to boot from FLASH
|
||||
4) Reset the DUE
|
||||
|
||||
Erase FLASH and Put the Due in Bootloader Mode
|
||||
----------------------------------------------
|
||||
This is accomplished by simply configuring the programming port in 1200
|
||||
baud and sending something on the programming port. Here is some sample
|
||||
output from a Windows CMD.exe shell. NOTE that my Arduino programming
|
||||
port shows up as COM26. It may be different on your system.
|
||||
|
||||
To enter boot mode, set the baud to 1200 and send anything to the
|
||||
programming port:
|
||||
|
||||
C:\Program Files (x86)\Arduino\arduino-1.5.2\hardware\tools>mode com26:1200,n,8,1
|
||||
|
||||

|
||||

Writing FLASH and Setting FLASH Boot Mode
|
||||
-----------------------------------------
|
||||
In a Cygwin BaSH shell:
|
||||
|
||||
export PATH="/cygdrive/c/Program Files (x86)/Arduino/arduino-1.5.2/hardware/tools":$PATH
|
||||
|
||||
Erasing, writing, and verifying FLASH with bossac:
|
||||
|
||||
$ bossac.exe --port=COM26 -U false -e -w -v -b nuttx.bin -R
|
||||
Erase flash
|
||||
Write 86588 bytes to flash
|
||||
[==============================] 100% (339/339 pages)
|
||||
Verify 86588 bytes of flash
|
||||
[==============================] 100% (339/339 pages)
|
||||
Verify successful
|
||||
Set boot flash true
|
||||
CPU reset.
|
||||
|
||||
Some things that can go wrong:
|
||||
|
||||
$ bossac.exe --port=COM26 -U false -e -w -v -b nuttx.bin -R
|
||||
No device found on COM26
|
||||
|
||||
This error means that there is code running on the Due already so the
|
||||
bootloader cannot connect. Pressing reset and trying again
|
||||
|
||||
$ bossac.exe --port=COM26 -U false -e -w -v -b nuttx.bin -R
|
||||
No device found on COM26
|
||||
|
||||
Sill No connection because Duo does not jump to bootloader after reset.
|
||||
Press ERASE button and try again
|
||||
|
||||
$ bossac.exe --port=COM26 -U false -e -w -v -b nuttx.bin -R
|
||||
Erase flash

You should be able to use a 10- to 20-pin adapter to connect a SAM-ICE
|
||||
debugger to the Arduino Due. I have this Olimex adapter:
|
||||
https://www.olimex.com/Products/ARM/JTAG/ARM-JTAG-20-10/ . But so far I
|
||||
have been unable to get the get the SAM-ICE to communicate with the Due.

Configurations
|
||||
^^^^^^^^^^^^^^
|
||||
|
||||
Each Arduino Due configuration is maintained in a sub-directory and
|
||||
can be selected as follow:
|
||||
|
||||
tools/configure.sh [OPTIONS] flipnclick-sam3x/<subdir>
|
||||
|
||||
Where typical options are -l to configure to build on Linux or -c to
|
||||
configure for Cygwin under Linux. 'tools/configure.sh -h' will show
|
||||
you all of the options.
|
||||
|
||||
Before building, make sure the PATH environment variable includes the
|
||||
correct path to the directory than holds your toolchain binaries.
|
||||
|
||||
And then build NuttX by simply typing the following. At the conclusion of
|
||||
the make, the nuttx binary will reside in an ELF file called, simply, nuttx.
|
||||
|
||||
make
|
||||
|
||||
The <subdir> that is provided above as an argument to the tools/configure.sh
|
||||
must be is one of the following.
|
||||
|
||||
NOTES:
|
||||
|
||||
1. These configurations use the mconf-based configuration tool. To
|
||||
change any of these 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.
|
||||
|
||||
2. Unless stated otherwise, all configurations generate console
|
||||
output on UART0 which is available both on the USB virtual COM port
|
||||
and on the PWML connector (see the section "Serial Consoles" above).
|
||||
|
||||
3. Unless otherwise stated, the configurations are setup for
|
||||
Cygwin under Windows:
|
||||
|
||||
Build Setup:
|
||||
CONFIG_HOST_WINDOWS=y : Microsoft Windows
|
||||
CONFIG_WINDIWS_CYGWIN=y : Cygwin under Windoes
|
||||
|
||||
3. All of these configurations are set up to build under Windows using the
|
||||
"GNU Tools for ARM Embedded Processors" that is maintained by ARM
|
||||
(unless stated otherwise in the description of the configuration).
|
||||
|
||||
https://developer.arm.com/open-source/gnu-toolchain/gnu-rm
|
||||
|
||||
That toolchain selection can easily be reconfigured using
|
||||
'make menuconfig'. Here are the relevant current settings:
|
||||
|
||||
System Type -> Toolchain:
|
||||
CONFIG_ARMV7M_TOOLCHAIN_GNU_EABIW=y : GNU ARM EABI toolchain for Windows
|
||||
|
||||
Configuration sub-directories
|
||||
-----------------------------
|
||||
|
||||
nsh:
|
||||
This configuration directory will build the NuttShell. See NOTES above.
|
||||
|
||||
NOTES:
|
||||
1. NSH built-in applications are supported. However, there are
|
||||
no built-in applications built with the default configuration.
|
||||
|
||||
Binary Formats:
|
||||
CONFIG_BUILTIN=y : Enable support for built-in programs
|
||||
|
||||
Applicaton Configuration:
|
||||
CONFIG_NSH_BUILTIN_APPS=y : Enable starting apps from NSH command line

* arg - The boardctl() argument is passed to the board_app_initialize()
|
||||
* implementation without modification. The argument has no
|
||||
* meaning to NuttX; the meaning of the argument is a contract
|
||||
* between the board-specific initialization logic and the
|
||||
* matching application logic. The value cold be such things as a
|
||||
* mode enumeration value, a set of DIP switch switch settings, a
|
||||
* pointer to configuration data read from a file or serial FLASH,
|
||||
* or whatever you would like to do with it. Every implementation
|

* should accept zero/NULL as a default configuration.
|
||||
*
|
||||
* Returned Value:
|
||||
* Zero (OK) is returned on success; a negated errno value is returned on

* any failure to indicate the nature of the failure.

* A high output value illuminates the LEDs.
|

*
|

* These LEDs are available to the application and are all available to the

* application unless CONFIG_ARCH_LEDS is defined. In that case, the usage
|
||||
* by the board port is defined in include/board.h and src/sam_autoleds.c.
|

* The LEDs are used to encode OS-related events as follows:
|
||||
*
|
||||
* SYMBOL MEANING LED STATE
|
||||
* L A B C D
|
||||
* ---------------- ----------------------- --- --- --- --- ---
|

* Thus if LED L is glowing on and all other LEDs are off (except LED D

* then a fatal error has been detected and the system has halted.
|

*
|

a good but empty state... all ready for file system re-organization.
|

- And worse, when NXFSS reorganization the FLASH a power cycle can
|
||||
damage the file system content if it happens at the wrong time.
|
||||
- The current design does not permit re-opening of files for write access
|
||||
unless the file is truncated to zero length. This effectively prohibits
|
||||
implementation of a proper turncate() method which should alter the
|
||||
size of a previously written file. There is some fragmentray logic in
|
||||
place but even this is conditioned out with __NO_TRUNCATE_SUPPORT__.
