Development Environment
|
||||
^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
Either Linux 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 Toolchain Options
|
||||
^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
The NuttX make system can be configured to support the various different
|
||||
toolchain options. All testing has been conducted using the NuttX buildroot
|
||||
toolchain. To use alternative toolchain, you simply need to add change of
|
||||
the following configuration options to your .config (or defconfig) file:
|
||||
|
||||
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery under Windows
|
||||
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYL=y : CodeSourcery under Linux
|
||||
CONFIG_ARMV7M_TOOLCHAIN_ATOLLIC=y : Atollic toolchain for Windos
|
||||
CONFIG_ARMV7M_TOOLCHAIN_DEVKITARM=y : devkitARM under Windows
|
||||
CONFIG_ARMV7M_TOOLCHAIN_BUILDROOT=y : NuttX buildroot under Linux or Cygwin (default)
|
||||
CONFIG_ARMV7M_TOOLCHAIN_GNU_EABIL=y : Generic GCC ARM EABI toolchain for Linux
|
||||
CONFIG_ARMV7M_TOOLCHAIN_GNU_EABIW=y : Generic GCC ARM EABI toolchain for Windows
|
||||
|
||||
You may also have to modify the PATH in the setenv.h file if your
|
||||
make cannot find the tools.
|
||||
|
||||
NOTE about Windows native toolchains
|
||||
------------------------------------
|
||||
|
||||
There are basically three kinds of GCC toolchains that can be used:
|
||||
|
||||
1. A Linux native toolchain in a Linux environment,
|
||||
2. The buildroot Cygwin tool chain built in the Cygwin environment,
|
||||
3. A Windows native toolchain.
|
||||
|
||||
There are several limitations to using a Windows based toolchain (#3) 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 paths which do
|
||||
not work with the Cygwin make.
|
||||
|
||||
MKDEP = $(TOPDIR)/tools/mknulldeps.sh
|
||||
|
||||
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 (There is a simple RIDE project
|
||||
in the RIDE subdirectory).
|
||||
|
||||
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/arm/src/sam34,
|
||||
arch/arm/src/common, arch/arm/src/armv7-m, 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/arm/src/sam34/sam_vectors.S. You may need to build NuttX
|
||||
one time from the Cygwin command line in order to obtain the pre-built
|
||||
startup object needed by RIDE.
|
||||
|
||||
NuttX EABI "buildroot" Toolchain
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
A GNU GCC-based toolchain is assumed. The files */setenv.sh should
|
||||
be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
|
||||
different from the default in your PATH variable).
|
||||
|
||||
If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
|
||||
SourceForge download site (https://sourceforge.net/projects/nuttx/files/buildroot/).
|
||||
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 sam4e-ek/<sub-dir>
|
||||
|
||||
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/cortexm3-eabi-defconfig-4.6.3 .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
|
||||
details PLUS some special instructions that you will need to follow if you are
|
||||
building a Cortex-M3 toolchain for Cygwin under Windows.
|
||||
|
||||
NOTE: Unfortunately, the 4.6.3 EABI toolchain is not compatible with the
|
||||
the NXFLAT tools. See the top-level TODO file (under "Binary loaders") for
|
||||
more information about this problem. If you plan to use NXFLAT, please do not
|
||||
use the GCC 4.6.3 EABI toochain; instead use the GCC 4.3.3 OABI toolchain.
|
||||
See instructions below.
|
||||
|
||||
NuttX OABI "buildroot" Toolchain
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
The older, OABI buildroot toolchain is also available. To use the OABI
|
||||
toolchain:
|
||||
|
||||
1. When building the buildroot toolchain, either (1) modify the cortexm3-eabi-defconfig-4.6.3
|
||||
configuration to use EABI (using 'make menuconfig'), or (2) use an exising OABI
|
||||
configuration such as cortexm3-defconfig-4.3.3
|
||||
|
||||
2. Modify the Make.defs file to use the OABI conventions:
|
||||
|
||||
+CROSSDEV = arm-nuttx-elf-
|
||||
+ARCHCPUFLAGS = -mtune=cortex-m3 -march=armv7-m -mfloat-abi=soft
|
||||
+NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-gotoff.ld -no-check-sections
|
||||
-CROSSDEV = arm-nuttx-eabi-
|
||||
-ARCHCPUFLAGS = -mcpu=cortex-m3 -mthumb -mfloat-abi=soft
|
||||
-NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-pcrel.ld -no-check-sections
|
||||
|
||||
NXFLAT Toolchain
|
||||
^^^^^^^^^^^^^^^^
|
||||
|
||||
If you are *not* using the NuttX buildroot toolchain and you want to use
|
||||
the NXFLAT tools, then you will still have to build a portion of the buildroot
|
||||
tools -- just the NXFLAT tools. The buildroot with the NXFLAT tools 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 sam4e-ek/<sub-dir>
|
||||
|
||||
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/cortexm3-defconfig-nxflat .config
|
||||
|
||||
6. make oldconfig
|
||||
|
||||
7. make
|
||||
|
||||
8. Edit setenv.h, if necessary, so that the PATH variable includes
|
||||
the path to the newly builtNXFLAT binaries.
|
||||
|
||||
AtmelStudio6.1
|
||||
^^^^^^^^^^^^^^
|
||||
|
||||
You can use AtmelStudio6.1 to load and debug code.
|
||||
|
||||
- To load code:
|
||||
|
||||
Tools -> Device Programming
|
||||
|
||||
Configure the debugger and chip and you are in business.
|
||||
|
||||
- To Debug Code:
|
||||
|
||||
File -> Open -> Open Object File for Debugging
|
||||
|
||||
Select the project name, the full path to the NuttX object (called
|
||||
just nuttx with no extension), and chip. Take the time to resolve
|
||||
all of the source file linkages or else you will not have source
|
||||
level debug!
|
||||
|
||||
LEDs
|
||||
^^^^
|
||||
|
||||
The SAM4E-EK board has three, user-controllable LEDs labelled D2 (blue),
|
||||
D3 (amber), and D4 (green) on the board. Usage of these LEDs is defined
|
||||
in include/board.h and src/up_leds.c. They are encoded as follows:
|
||||
|
||||
SYMBOL Meaning D3* D2 D4
|
||||
------------------- ----------------------- ------- ------- -------
|
||||
LED_STARTED NuttX has been started OFF OFF OFF
|
||||
LED_HEAPALLOCATE Heap has been allocated OFF OFF ON
|
||||
LED_IRQSENABLED Interrupts enabled OFF ON OFF
|
||||
LED_STACKCREATED Idle stack created OFF ON ON
|
||||
LED_INIRQ In an interrupt** N/C FLASH N/C
|
||||
LED_SIGNAL In a signal handler*** N/C N/C FLASH
|
||||
LED_ASSERTION An assertion failed FLASH N/C N/C
|
||||
LED_PANIC The system has crashed FLASH N/C N/C
|
||||
|
||||
* If D2 and D4 are statically on, then NuttX probably failed to boot
|
||||
and these LEDs will give you some indication of where the failure was
|
||||
** The normal state is D3=OFF, D4=ON and D2 faintly glowing. This faint
|
||||
glow is because of timer interrupts that result in the LED being
|
||||
illuminated on a small proportion of the time.
|
||||
*** D4 may also flicker normally if signals are processed.
|
||||
|
||||
Serial Console
|
||||
^^^^^^^^^^^^^^
|
||||
|
||||
By default, all of these configurations use UART0 for the NuttX serial
|
||||
console. UART0 corresponds to the DB-9 connector labelled "UART". This
|
||||
is a male connector and will require a female-to-female, NUL modem cable
|
||||
to connect to a PC.
|
||||
|
||||
An alternate is USART1 which connects to the other DB-9 connector labeled
|
||||
"USART". USART1 is not enabled by default unless specifically noted
|
||||
otherwise in the configuration description. A NUL modem cable must be
|
||||
used with the port as well.
|
||||
|
||||
NOTE: One of the USART1 pins is shared with the audio CODEC. The audio
|
||||
CODEC cannot be used of USART1 is enabled.
|
||||
|
||||
By default serial console is configured for 115000, 8-bit, 1 stop bit, and
|
||||
no parity.
|
||||
|
||||
SAM4E-EK-specific Configuration Options
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
CONFIG_ARCH - Identifies the arch/ subdirectory. This should
|
||||
be set to:
|
||||
|
||||
CONFIG_ARCH=arm
|
||||
|
||||
CONFIG_ARCH_family - For use in C code:
|
||||
|
||||
CONFIG_ARCH_ARM=y
|
||||
|
||||
CONFIG_ARCH_architecture - For use in C code:
|
||||
|
||||
CONFIG_ARCH_CORTEXM3=y
|
||||
|
||||
CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
|
||||
|
||||
CONFIG_ARCH_CHIP="sam34"
|
||||
|
||||
CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
|
||||
chip:
|
||||
|
||||
CONFIG_ARCH_CHIP_SAM34
|
||||
CONFIG_ARCH_CHIP_SAM3U
|
||||
CONFIG_ARCH_CHIP_ATSAM3U4
|
||||
|
||||
CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
|
||||
hence, the board that supports the particular chip or SoC.
|
||||
|
||||
CONFIG_ARCH_BOARD=sam4e-ek (for the SAM4E-EK development board)
|
||||
|
||||
CONFIG_ARCH_BOARD_name - For use in C code
|
||||
|
||||
CONFIG_ARCH_BOARD_SAM4EEK=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=0x00020000 (128Kb)
|
||||
|
||||
CONFIG_RAM_START - The start address of installed DRAM
|
||||
|
||||
CONFIG_RAM_START=0x20000000
|
||||
|
||||
CONFIG_ARCH_IRQPRIO - The SAM3U supports interrupt prioritization
|
||||
|
||||
CONFIG_ARCH_IRQPRIO=n
|
||||
|
||||
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.
|
||||
|
||||

Configurations
|
||||
^^^^^^^^^^^^^^
|
||||
|
||||
Information Common to All Configurations
|
||||
----------------------------------------
|
||||
Each SAM4E-EK configuration is maintained in a sub-directory and
|
||||
can be selected as follow:
|
||||
|
||||
cd tools
|
||||
./configure.sh sam4e-ek/<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.
|
||||
|
||||
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 on UART0 (J3).
|
||||
|
||||
3. Unless otherwise stated, the configurations are setup for
|
||||
Linux (or any other POSIX environment like Cygwin under Windows):
|
||||
|
||||
Build Setup:
|
||||
CONFIG_HOST_LINUX=y : Linux or other POSIX environment
|
||||
|
||||
4. All of these configurations use the older, OABI, buildroot toolchain
|
||||
(unless stated otherwise in the description of the configuration). That
|
||||
toolchain selection can easily be reconfigured using 'make menuconfig'.
|
||||
Here are the relevant current settings:
|
||||
|
||||
Build Setup:
|
||||
CONFIG_HOST_LINUX=y : Linux or other pure POSIX invironment
|
||||
: (including Cygwin)
|
||||
System Type -> Toolchain:
|
||||
CONFIG_ARMV7M_TOOLCHAIN_BUILDROOT=y : Buildroot toolchain
|
||||
CONFIG_ARMV7M_OABI_TOOLCHAIN=y : Older, OABI toolchain
|
||||
|
||||
If you want to use the Atmel GCC toolchain, for example, here are the
|
||||
steps to do so:
|
||||
|
||||
Build Setup:
|
||||
CONFIG_HOST_WINDOWS=y : Windows
|
||||
CONFIG_HOST_CYGWIN=y : Using Cygwin or other POSIX environment
|
||||
|
||||
System Type -> Toolchain:
|
||||
CONFIG_ARMV7M_TOOLCHAIN_GNU_EABIW=y : General GCC EABI toolchain under windows
|
||||
|
||||
Library Routines ->
|
||||
CONFIG_CXX_NEWLONG=n : size_t is an unsigned int, not long
|
||||
|
||||
This 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 sam4e-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 call
|
||||
"GNU Toolchain Options" above.
|
||||
|
||||
Configuration sub-directories
|
||||
-----------------------------
|
||||
|
||||
nsh:
|
||||
Configures the NuttShell (nsh) located at examples/nsh. The
|
||||
Configuration enables both the serial and telnetd NSH interfaces.
|
||||
|
||||
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
|
||||
|
||||
2. This configuration has been used for verifying the touchscreen on
|
||||
on the SAM4E-EK LCD. With these modifications, you can include the
|
||||
touchscreen test program at apps/examples/touchscreen as an NSH built-in
|
||||
application. You can enable the touchscreen and test by modifying the
|
||||
default configuration in the following ways:
|
||||
|
||||
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_INPUT=y : Enable support for input devices
|
||||
CONFIG_INPUT_ADS7843E=y : Enable support for the XPT2046
|
||||
CONFIG_ADS7843E_SPIDEV=2 : Use SPI CS 2 for communication
|
||||
CONFIG_ADS7843E_SPIMODE=0 : Use SPI mode 0
|
||||
CONFIG_ADS7843E_FREQUENCY=1000000 : SPI BAUD 1MHz
|
||||
CONFIG_ADS7843E_SWAPXY=y : If landscpe orientation
|
||||
CONFIG_ADS7843E_THRESHX=51 : These will probably need to be tuned
|
||||
CONFIG_ADS7843E_THRESHY=39
|
||||
|
||||
System Type -> Peripherals:
|
||||
CONFIG_SAM34_SPI0=y : Enable support for SPI
|
||||
|
||||
System Type:
|
||||
CONFIG_GPIO_IRQ=y : GPIO interrupt support
|
||||
CONFIG_GPIOA_IRQ=y : Enable GPIO interrupts from port A
|
||||
|
||||
RTOS Features:
|
||||
CONFIG_DISABLE_SIGNALS=n : Signals are required
|
||||
|
||||
Library Support:
|
||||
CONFIG_SCHED_WORKQUEUE=y : Work queue support required
|
||||
|
||||
Applicaton Configuration:
|
||||
CONFIG_EXAMPLES_TOUCHSCREEN=y : Enable the touchscreen built-int test
|
||||
|
||||
Defaults should be okay for related touchscreen settings. Touchscreen
|
||||
debug output on UART0 can be enabled with:
|
||||
|
||||
Build Setup:
|
||||
CONFIG_DEBUG=y : Enable debug features
|
||||
CONFIG_DEBUG_VERBOSE=y : Enable verbose debug output
|
||||
CONFIG_DEBUG_INPUT=y : Enable debug output from input devices
|
||||
|
||||
3. Enabling HSMCI support. The SAM3U-KE provides a an SD memory card
|
||||
slot. Support for the SD slot can be enabled with the following
|
||||
settings:
|
||||
|
||||
System Type->ATSAM3/4 Peripheral Support
|
||||
CONFIG_SAM34_HSMCI=y : Enable HSMCI support
|
||||
CONFIG_SAM34_DMAC=y : DMAC support is needed by HSMCI
|
||||
|
||||
System Type
|
||||
CONFIG_SAM34_GPIO_IRQ=y : PIO interrupts needed
|
||||
CONFIG_SAM34_GPIOA_IRQ=y : Card detect pin is on PIOA
|
||||
|
||||
Device Drivers -> MMC/SD Driver Support
|
||||

|
||||
CONFIG_SDIO_BLOCKSETUP=y : Needs to know block sizes
|
||||
|
||||
Library Routines
|
||||
CONFIG_SCHED_WORKQUEUE=y : Driver needs work queue support
|
||||
|
||||
Application Configuration -> NSH Library
|
||||
CONFIG_NSH_ARCHINIT=y : NSH board-initialization
|
||||
|
||||
STATUS:
|
||||
2013-6-28: The touchscreen is functional.
|
||||
2013-6-29: Hmmm... but there appear to be conditions when the
|
||||
touchscreen driver locks up. Looks like some issue with
|
||||
managing the interrupts.
|
||||
2013-6-30: Those lock-ups appear to be due to poorly placed
|
||||
debug output statements. If you do not enable debug output,
|
||||
the touchscreen is rock-solid.
|
||||
2013-8-10: Added the comments above above enabling HSMCI memory
|
||||
card support and verified that the configuration builds without
|
||||
error. However, that configuration has not yet been tested (and
|
||||
is may even be incomplete).

/* The SAM4E-EK board has three, user-controllable LEDs labelled D2 (blue),
|

* D3 (amber), and D4 (green) on the board. Usage of these LEDs is defined
|
||||
* in include/board.h and src/up_leds.c. They are encoded as follows:
|
||||
*
|
||||
* SYMBOL Meaning D3* D2 D4
|
||||
* ------------------- ----------------------- ------- ------- -------
|
||||
* LED_STARTED NuttX has been started OFF OFF OFF
|
||||
* LED_HEAPALLOCATE Heap has been allocated OFF OFF ON
|
||||
* LED_IRQSENABLED Interrupts enabled OFF ON OFF
|
||||
* LED_STACKCREATED Idle stack created OFF ON ON
|
||||
* LED_INIRQ In an interrupt** N/C FLASH N/C
|
||||
* LED_SIGNAL In a signal handler*** N/C N/C FLASH
|
||||
* LED_ASSERTION An assertion failed FLASH N/C N/C
|
||||
* LED_PANIC The system has crashed FLASH N/C N/C
|
||||
*
|
||||
* * If D2 and D4 are statically on, then NuttX probably failed to boot
|
||||
* and these LEDs will give you some indication of where the failure was
|
||||
* ** The normal state is D3=OFF, D4=ON and D2 faintly glowing. This faint
|
||||
* glow is because of timer interrupts that result in the LED being
|
||||
* illuminated on a small proportion of the time.
|
||||
* *** D4 may also flicker normally if signals are processed.

|

*
|
||||
* Description:
|
||||
* These external functions must be provided by board-specific logic. They
|
||||
* include:
|
||||
*
|
||||
* o sam_spiselect is a functions tomanage the board-specific chip selects
|
||||
* o sam_spistatus and sam_spicmddata: Implementations of the status
|
||||
* and cmddata methods of the SPI interface defined by struct spi_ops_
|
||||
* (see include/nuttx/spi/spi.h). All other methods including
|
||||
* up_spiinitialize()) are provided by common SAM3/4 logic.
|
||||
*
|
||||
* To use this common SPI logic on your board:
|
||||
*
|
||||
* 1. Provide logic in sam_boardinitialize() to configure SPI chip select
|
||||
* pins.
|
||||
* 2. Provide sam_spiselect() and sam_spistatus() functions in your board-
|
||||
* specific logic. These functions will perform chip selection and
|
||||
* status operations using GPIOs in the way your board is configured.
|
||||
* 2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
|
||||
* sam_spicmddata() 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).

* 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.
|
