README
======
This README discusses issues unique to NuttX configurations for the
Atmel SAMD21 Xplained Pro development board. This board features the
ATSAMD21J18A MCU.
The SAMD21 Xplained Pro Starter Kit may be bundled with three modules:
1) I/O1 - An MMC/SD card slot, PWM LED control, ADC light sensor, USART
loopback, TWI AT30TSE758 Temperature sensor.
2) OLED1 - An OLED plus 3 additional switches and 3 additional LEDs
3) PROTO1 - A prototyping board with logic on board (other than power-related
logic).

STATUS/ISSUES
=============
1. See configs/samd20-xplained/README.txt. This port derives from the
SAMD20 Xplained board board and all issues there should apply.
2. As of this writing, no testing has been performed. The board is on
order and testing will begin when I have the board in hand.
Modules
=======
There are several I/O modules available that will work with the SAMD21
Xplained Pro Starter Kit:
1) I/O1 - An MMC/SD card slot, PWM LED control, ADC light sensor, USART
loopback, TWI AT30TSE758 Temperature sensor.
2) OLED1 - An OLED plus 3 additional switches and 3 additional LEDs
3) PROTO1 - A prototyping board with logic on board (other than power-
related logic).
4) And others. See http://www.atmel.com/products/microcontrollers/avr/xplained.aspx
Some of these are discussed further below.
I/O1
----
The primary function of this module is to provide SD card support, but
the full list of modules features include:
- microSD card connector (SPI interface)
- PWM (LED control)
- ADC (light sensor)
- USART loopback
- TWI AT30TSE758 Temperature sensor with EEPROM
SPI is available on two of the SAMD21 Xplained connectors, EXT1 and EXT2.
They mate with the I/O1 connector as indicated in this table.

Configuration Options:
----------------------
CONFIG_SAMD21_XPLAINED_OLED1MODULE=y : Informs the system that the
I/O1 module is installed
CONFIG_SAMD21_XPLAINED_OLED1MODULE_EXT1=y : The module is installed in EXT1
CONFIG_SAMD21_XPLAINED_OLED1MODULE_EXT2=y : The mdoule is installed in EXT2
See the set-up in the discussion of the nsh configuration below for other
required configuration options.
PROTO1
------
A prototyping board with logic on board (other than power-related logic).
There is no built-in support for the PROTO1 module.
LEDs
====
There is one yellow LED available on the SAM D20 Xplained Pro board that
can be turned on and off. The LED can be activated by driving the connected
PB30 I/O line to GND.
When CONFIG_ARCH_LEDS is defined in the NuttX configuration, NuttX will
control the LED as follows:
SYMBOL Meaning LED0
------------------- ----------------------- ------
LED_STARTED NuttX has been started OFF
LED_HEAPALLOCATE Heap has been allocated OFF
LED_IRQSENABLED Interrupts enabled OFF
LED_STACKCREATED Idle stack created ON
LED_INIRQ In an interrupt N/C
LED_SIGNAL In a signal handler N/C
LED_ASSERTION An assertion failed N/C
LED_PANIC The system has crashed FLASH
Thus is LED is statically on, NuttX has successfully booted and is,
apparently, running normally. If LED is flashing at approximately
2Hz, then a fatal error has been detected and the system has halted.
Serial Consoles
===============
SERCOM4
------
SERCOM4 is available on connectors EXT1, EXT2, and EXT3, but using
different PORT pins:
PIN EXT1 EXT2 EXT3 GPIO Function
---- ---- ---- ---- ------------------
13 PB09 PB10 PB10 SERCOM4 / USART RX
14 PB08 PB11 PB11 SERCOM4 / USART TX
19 GND GND GND N/A
20 VCC VCC VCC N/A
There are options available in the NuttX configuration to select which
connector SERCOM4 is on: SAMD21_XPLAINED_USART4_EXTn, where n=1, 2, or 3.
If you have a TTL to RS-232 converter then this is the most convenient
serial console to use (because you don't lose the console device each time
you lose the USB connection). It is the default in all of these
configurations. An option is to use the virtual COM port.
Virtual COM Port
----------------
The SAMD21 Xplained Pro contains an Embedded Debugger (EDBG) that can be
used to program and debug the ATSAMD21J18A using Serial Wire Debug (SWD).
The Embedded debugger also include a Virtual COM port interface over
SERCOM3. Virtual COM port connections:
PA22 SERCOM3 / USART TXD
PA23 SERCOM3 / USART RXD
Atmel Studio 6.1
================
Loading Code into FLASH:
-----------------------
Tools menus: Tools -> Device Programming.
Debugging the NuttX Object File
-------------------------------
1) Rename object file from nutt to nuttx.elf. That is an extension that
will be recognized by the file menu.
2) File menu: File -> Open -> Open object file for debugging
- Select nuttx.elf object file
- Select AT91SAMD21J18
- Select files for symbols as desired
- Select debugger
3) Debug menu: Debug -> Start debugging and break
- This will reload the nuttx.elf file into FLASH
SAMD21 Xplained Pro-specific Configuration Options

chip:
CONFIG_ARCH_CHIP_SAMD
CONFIG_ARCH_CHIP_SAMD21
CONFIG_ARCH_CHIP_ATSAMD21J18
CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
hence, the board that supports the particular chip or SoC.
CONFIG_ARCH_BOARD=samd21-xplained (for the SAMD21 Xplained Pro development board)
CONFIG_ARCH_BOARD_name - For use in C code
CONFIG_ARCH_BOARD_SAMD21_XPLAINED=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 (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

Configurations
==============
Each SAMD21 Xplained Pro configuration is maintained in a sub-directory and
can be selected as follow:
cd tools
./configure.sh samd21-xplained/<subdir>
cd -
. ./setenv.sh
Before sourcing the setenv.sh file above, you should examine it and perform
edits as necessary so that BUILDROOT_BIN is 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.
NOTE: 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
and misc/tools/
b. Execute 'make menuconfig' in nuttx/ in order to start the
reconfiguration process.
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
and misc/tools/
b. Execute 'make menuconfig' in nuttx/ in order to start the
reconfiguration process.
2. Unless stated otherwise, all configurations generate console
output of on SERCOM4 which is available on EXT1, EXT2, or EXT3 (see
the section "Serial Consoles" above). The virtual COM port could
be used, instead, by reconfiguring to use SERCOM3 instead of
SERCOM4:
System Type -> SAMD/L Peripheral Support
CONFIG_SAMDL_SERCOM3=y : Enable one or both
CONFIG_SAMDL_SERCOM4=n
Device Drivers -> Serial Driver Support -> Serial Console
CONFIG_USART4_SERIAL_CONSOLE=y : Select only one for the console
CONFIG_USART4_SERIAL_CONSOLE=n
Device Drivers -> Serial Driver Support -> SERCOM3 Configuration
CONFIG_USART3_2STOP=0
CONFIG_USART3_BAUD=115200
CONFIG_USART3_BITS=8
CONFIG_USART3_PARITY=0
CONFIG_USART3_RXBUFSIZE=256
CONFIG_USART3_TXBUFSIZE=256
Device Drivers -> Serial Driver Support -> SERCOM4 Configuration
CONFIG_USART4_2STOP=0
CONFIG_USART4_BAUD=115200
CONFIG_USART4_BITS=8
CONFIG_USART4_PARITY=0
CONFIG_USART4_RXBUFSIZE=256
CONFIG_USART4_TXBUFSIZE=256
Board Selection -> USART4 Connection
CONFIG_SAMD21_XPLAINED_USART4_EXT1=n : Pick on if USART4 used
CONFIG_SAMD21_XPLAINED_USART4_EXT2=n
CONFIG_SAMD21_XPLAINED_USART4_EXT3=y
3. Unless otherwise stated, the configurations are setup for
Cygwin under Windows:
Build Setup:
CONFIG_HOST_WINDOWS=y : Windows Host
CONFIG_WINDOWS_CYGWIN=y : Cygwin environment on windoes
4. These configurations use the CodeSourcery toolchain. But
that is easily reconfigured:
System Type -> Toolchain:
CONFIG_ARMV6M_TOOLCHAIN_CODESOURCERYW=y
Any re-configuration should be done before making NuttX or else the
subsequent 'make' will fail. If you have already attempted building
NuttX then you will have to 1) 'make distclean' to remove the old
configuration, 2) 'cd tools; ./configure.sh sam3u-ek/ksnh' to start
with a fresh configuration, and 3) perform the configuration changes
above.
Also, make sure that your PATH variable has the new path to your
Atmel tools. Try 'which arm-none-eabi-gcc' to make sure that you
are selecting the right tool. setenv.sh is available for you to
use to set or PATH variable. The path in the that file may not,
however, be correct for your installation.
See also the "NOTE about Windows native toolchains" in the section
called "GNU Toolchain Options" above.
Configuration sub-directories

PIN EXT3 GPIO Function
---- ---- ------------------
13 PB11 SERCOM4 / USART RX
14 PB10 SERCOM4 / USART TX
19 GND N/A
20 VCC N/A
If you would prefer to use the EDBG serial COM port or would prefer
to use SERCOM4 on EXT1 or EXT2, you will need to reconfigure the
SERCOM as described under "Configurations". See also the section
entitled "Serial Consoles" above.
3. NOTE: If you get a compilation error like:
libxx_new.cxx:74:40: error: 'operator new' takes type 'size_t'
('unsigned int') as first parameter [-fper
Sometimes NuttX and your toolchain will disagree on the underlying
type of size_t; sometimes it is an 'unsigned int' and sometimes it is
an 'unsigned long int'. If this error occurs, then you may need to
toggle the value of CONFIG_CXX_NEWLONG.
4. If the I/O1 module is connected to the SAMD21 Xplained Pro, then
support for the SD card slot can be enabled by making the following
changes to the configuration. These changes assume that the I/O1
modules is connected in EXT1. Most of the modifications necessary
to work with the I/O1 in a different connector are obvious.. except
for the selection of SERCOM SPI support:
EXT1: SPI is provided through SERCOM0
EXT2: SPI is provided through SERCOM1
EXT3: SPI is provided through SERCOM5
File Systems:
CONFIG_FS_FAT=y : Enable the FAT file system
CONFIG_FAT_LCNAMES=y : Enable upper/lower case 8.3 file names (Optional, see below)
CONFIG_FAT_LFN=y : Enable long file named (Optional, see below)
CONFIG_FAT_MAXFNAME=32 : Maximum supported file name length
There are issues related to patents that Microsoft holds on FAT long
file name technologies. See the top level COPYING file for further
details.
System Type -> Peripherals:
CONFIG_SAMDL_SERCOM0=y : Use SERCOM0 if the I/O is in EXT1
CONFIG_SAMDL_SERCOM0_ISSPI=y : Configure SERCOM0 as an SPI master
Device Drivers
CONFIG_SPI=y : Enable SPI support
CONFIG_SPI_EXCHANGE=y : The exchange() method is supported
CONFIG_SPI_OWNBUS=y : Smaller code if this is the only SPI device
CONFIG_MMCSD=y : Enable MMC/SD support
CONFIG_MMCSD_NSLOTS=1 : Only one MMC/SD card slot
CONFIG_MMCSD_MULTIBLOCK_DISABLE=n : Should not need to disable multi-block transfers
CONFIG_MMCSD_MMCSUPPORT=n : May interfere with some SD cards
CONFIG_MMCSD_HAVECARDDETECT=y : I/O1 module as a card detect GPIO
CONFIG_MMCSD_SPI=y : Use the SPI interface to the MMC/SD card
CONFIG_MMCSD_SPICLOCK=20000000 : This is a guess for the optimal MMC/SD frequency
CONFIG_MMCSD_SPIMODE=0 : Mode 0 is required
Board Selection -> Common Board Options
CONFIG_NSH_MMCSDSLOTNO=0 : Only one MMC/SD slot, slot 0
CONFIG_NSH_MMCSDSPIPORTNO=0 : Use port=0 -> SERCOM0 if the I/O1 is in EXT1
Board Selection -> SAMD21 Xplained Pro Modules
CONFIG_SAMD21_XPLAINED_IOMODULE=y : I/O1 module is connected
CONFIG_SAMD21_XPLAINED_IOMODULE_EXT1=y : I/O1 modules is in EXT1
Application Configuration -> NSH Library
CONFIG_NSH_ARCHINIT=y : Board has architecture-specific initialization
NOTE: If you enable the I/O1 this configuration with SERCOM4 as the
console and with the I/O1 module in EXT1, you *must* remove USART
jumper. Otherwise, you have lookpack on SERCOM4 and NSH will *not*
behave very well (since its outgoing prompts also appear as incoming
commands).
STATUS: As of 2013-6-18, this configuration appears completely
functional. Testing, however, has been very light. Example:
NuttShell (NSH) NuttX-6.34
nsh> mount -t vfat /dev/mmcsd0 /mnt/stuff
nsh> ls /mnt/stuff
/mnt/stuff:
nsh> echo "This is a test" >/mnt/stuff/atest.txt
nsh> ls /mnt/stuff
/mnt/stuff:
atest.txt
nsh> cat /mnt/stuff/atest.txt
This is a test
nsh>
5. If the OLED1 module is connected to the SAMD21 Xplained Pro, then
support for the OLED display can be enabled by making the following
changes to the configuration. These changes assume that the I/O1
modules is connected in EXT1. Most of the modifications necessary
to work with the I/O1 in a different connector are obvious.. except
for the selection of SERCOM SPI support:
EXT1: SPI is provided through SERCOM0
EXT2: SPI is provided through SERCOM1
EXT3: SPI is provided through SERCOM5
System Type -> Peripherals:
CONFIG_SAMDL_SERCOM1=y : Use SERCOM1 if the I/O is in EXT2
CONFIG_SAMDL_SERCOM1_ISSPI=y : Configure SERCOM1 as an SPI master
Device Drivers -> SPI
CONFIG_SPI=y : Enable SPI support
CONFIG_SPI_EXCHANGE=y : The exchange() method is supported
CONFIG_SPI_CMDDATA=y : CMD/DATA support is required
CONFIG_SPI_OWNBUS=y : Smaller code if this is the only SPI device
Device Drivers -> LCDs
CONFIG_LCD=y : Enable LCD support
CONFIG_LCD_MAXCONTRAST=255 : Maximum contrast value
CONFIG_LCD_LANDSCAPE=y : Landscape orientation (see below*)
CONFIG_LCD_UG2832HSWEG04=y : Enable support for the OLED
CONFIG_LCD_SSD1306_SPIMODE=0 : SPI Mode 0
CONFIG_LCD_SSD1306_SPIMODE=3500000 : Pick an SPI frequency
Board Selection -> SAMD21 Xplained Pro Modules
CONFIG_SAMD21_XPLAINED_OLED1MODULE=y : OLED1 module is connected
CONFIG_SAMD21_XPLAINED_OLED1MODULE_EXT2=y : OLED1 modules is in EXT2
The NX graphics subsystem also needs to be configured:
CONFIG_NX=y : Enable graphics support
CONFIG_NX_LCDDRIVER=y : Using an LCD driver
CONFIG_NX_NPLANES=1 : With a single color plane
CONFIG_NX_WRITEONLY=n : You can read from the LCD (see below**)
CONFIG_NX_DISABLE_2BPP=y : Disable all resolutions except 1BPP
CONFIG_NX_DISABLE_4BPP=y
CONFIG_NX_DISABLE_8BPP=y
CONFIG_NX_DISABLE_16BPP=y
CONFIG_NX_DISABLE_24BPP=y
CONFIG_NX_DISABLE_32BPP=y
CONFIG_NX_PACKEDMSFIRST=y : LSB packed first (shouldn't matter)
CONFIG_NXTK_BORDERWIDTH=2 : Use a small border
CONFIG_NXTK_DEFAULT_BORDERCOLORS=y : Default border colors
CONFIG_NXFONTS_CHARBITS=7 : 7-bit fonts
CONFIG_NXFONT_SANS17X23B=y : Pick a font (any that will fit)
* This orientation will put the buttons "above" the LCD. The
reverse landscape configuration (CONFIG_LCD_RLANDSCAPE) will
"flip" the display so that the buttons are "below" the LCD.
** The hardware is write only, but the driver maintains a frame buffer
to support read and read-write-modiry operations on the LCD.
Reading from the frame buffer is, however, untested.
Then, in order to use the OLED, you will need to build some kind of
graphics application or use one of the NuttX graphics examples.
Here, for example, is the setup for the graphic "Hello, World!"
example:
CONFIG_EXAMPLES_NXHELLO=y : Enables the example
CONFIG_EXAMPLES_NXHELLO_DEFAULT_COLORS=y : Use default colors (see below *)
CONFIG_EXAMPLES_NXHELLO_DEFAULT_FONT=y : Use the default font
CONFIG_EXAMPLES_NXHELLO_BPP=1 : One bit per pixel
CONFIG_EXAMPLES_NXHELLO_EXTERNINIT=y : Special initialization is required.
* The OLED is monochrome so the only "colors" are blacka nd white.
The default "colors" will give you while text on a black background.
You can override the faults it you want black text on a while background.
NOTE: One issue that I have seen with the NXHello example when
running as an NSH command is that it only works the first time.
So, after you run the 'nxhello' command one time, you will have to
reset the board before you run it again.
This is clearly some issue with initializing, un-initializing, and
then re-initializing. If you want to fix this, patches are quite
welcome.

/* There are three LEDs on board the SAMD21 Xplained Pro board: The EDBG
* controls two of the LEDs, a power LED and a status LED. There is only
* one user controllable LED, a yellow LED labelled STATUS near the SAMD21 USB
* connector.
*
* This LED is controlled by PB30 and the LED can be activated by driving PB30
* to GND.
*
* When CONFIG_ARCH_LEDS is defined in the NuttX configuration, NuttX will
* control the LED as follows:
*
* SYMBOL Meaning LED
* ------------------- ----------------------- ------
* LED_STARTED NuttX has been started OFF
* LED_HEAPALLOCATE Heap has been allocated OFF
* LED_IRQSENABLED Interrupts enabled OFF
* LED_STACKCREATED Idle stack created ON
* LED_INIRQ In an interrupt** N/C
* LED_SIGNAL In a signal handler*** N/C
* LED_ASSERTION An assertion failed N/C
* LED_PANIC The system has crashed FLASH
*
* Thus if the LED is statically on, NuttX has successfully booted and is,
* apparently, running normally. If the LED is flashing at approximately
* 2Hz, then a fatal error has been detected and the system has halted.

* 2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
* sam_spi[n]cmddata() functions in your board-specific logic. This
* function will perform cmd/data selection operations using GPIOs in
* the way your board is configured.
* 3. Add a call to up_spiinitialize() in your low level application
* initialization logic
* 4. The handle returned by up_spiinitialize() may then be used to bind
* the SPI driver to higher level logic (e.g., calling
* mmcsd_spislotinitialize(), for example, will bind the SPI driver to
* the SPI MMC/SD driver).

/****************************************************************************
* Name: sam_spi[n]select
*
* Description:
* PIO chip select pins may be programmed by the board specific logic in
* one of two different ways. First, the pins may be programmed as SPI
* peripherals. In that case, the pins are completely controlled by the
* SPI driver. This method still needs to be provided, but it may be only
* a stub.
*
* An alternative way to program the PIO chip select pins is as a normal
* GPIO output. In that case, the automatic control of the CS pins is
* bypassed and this function must provide control of the chip select.
* NOTE: In this case, the GPIO output pin does *not* have to be the
* same as the NPCS pin normal associated with the chip select number.
*
* Input Parameters:
* dev - SPI device info
* devid - Identifies the (logical) device
* selected - TRUE:Select the device, FALSE:De-select the device
*
* Returned Values:
* None
