On-Board GPIO Usage
===================
[To be provided]
Using OpenOCD and GDB with an FT2232 JTAG emulator
==================================================
Building OpenOCD under Cygwin:
Refer to configs/olimex-lpc1766stk/README.txt
Installing OpenOCD in Linux:
sudo apt-get install openocd
You can also build openocd from its source:
git clone http://git.code.sf.net/p/openocd/code openocd
cd openocd
Helper Scripts:
I have been using the on-board In-Circuit Debug Interface (ICDI) interface.
OpenOCD requires a configuration file. I keep the one I used last here:
configs/dk-tm4c129x/tools/dk-tm4c129x.cfg
However, the "correct" configuration script to use with OpenOCD may
change as the features of OpenOCD evolve. So you should at least
compare that dk-tm4c129x.cfg file with configuration files in
/usr/share/openocd/scripts. As of this writing, the configuration
files of interest were:
/usr/local/share/openocd/scripts/board/dk-tm4c129x.cfg
/usr/local/share/openocd/scripts/interface/ti-icdi.cfg
/usr/local/share/openocd/scripts/target/stellaris_icdi.cfg
There is also a script on the tools/ directory that I use to start
the OpenOCD daemon on my system called oocd.sh. That script will
probably require some modifications to work in another environment:
- Possibly the value of OPENOCD_PATH and TARGET_PATH
- It assumes that the correct script to use is the one at
configs/dk-tm4c129x/tools/dk-tm4c129x.cfg
Starting OpenOCD
If you are in the top-level NuttX build directlory then you should
be able to start the OpenOCD daemon like:
oocd.sh $PWD
The relative path to the oocd.sh script is configs/dk-tm4c129x/tools,
but that should have been added to your PATH variable when you sourced
the setenv.sh script.
Note that OpenOCD needs to be run with administrator privileges in
some environments (sudo).
Connecting GDB
Once the OpenOCD daemon has been started, you can connect to it via
GDB using the following GDB command:
arm-nuttx-elf-gdb
(gdb) target remote localhost:3333
NOTE: The name of your GDB program may differ. For example, with the
CodeSourcery toolchain, the ARM GDB would be called arm-none-eabi-gdb.
After starting GDB, you can load the NuttX ELF file:
(gdb) symbol-file nuttx
(gdb) monitor reset
(gdb) monitor halt
(gdb) load nuttx
NOTES:
1. Loading the symbol-file is only useful if you have built NuttX to
include debug symbols (by setting CONFIG_DEBUG_SYMBOLS=y in the
.config file).
2. The MCU must be halted prior to loading code using 'mon reset'
as described below.
OpenOCD will support several special 'monitor' commands. These
GDB commands will send comments to the OpenOCD monitor. Here
are a couple that you will need to use:
(gdb) monitor reset
(gdb) monitor halt
NOTES:
1. The MCU must be halted using 'mon halt' prior to loading code.
2. Reset will restart the processor after loading code.
3. The 'monitor' command can be abbreviated as just 'mon'.
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 has been modified to support the following different
toolchain options.
1. The NuttX buildroot Toolchain (default, see below),
2. The CodeSourcery GNU toolchain,
3. The devkitARM GNU toolchain,
4. The Atollic toolchain, or
5. The Code Red toolchain
All testing has been conducted using the Buildroot toolchain for Cygwin/Linux.
To use a different toolchain, you simply need to add one of the following
configuration options to your .config (or defconfig) file:
CONFIG_ARMV7M_TOOLCHAIN_BUILDROOT=y : NuttX buildroot under Linux or Cygwin (default)
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery under Windows or Cygwin
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYL=y : CodeSourcery under Linux
CONFIG_ARMV7M_TOOLCHAIN_DEVKITARM=y : The Atollic toolchain under Windows or Cygwin
CONFIG_ARMV7M_TOOLCHAIN_CODEREDW=y : The Code Red toolchain under Windows
CONFIG_ARMV7M_TOOLCHAIN_CODEREDL=y : The Code Red toolchain under Linux
CONFIG_ARMV7M_OABI_TOOLCHAIN=y : If you use an older, OABI buildroot toolchain
If you change the default toolchain, then you may also have to modify the PATH in
the setenv.h file if your make cannot find the tools.
NOTE: the CodeSourcery (for Windows), Atollic, devkitARM, and Code Red (for Windows)
toolchains are Windows native toolchains. The CodeSourcey (for Linux) and NuttX
buildroot toolchains are Cygwin and/or Linux native toolchains. There are several
limitations to using a Windows based toolchain 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 pathes which do not
work with the Cygwin make.
MKDEP = $(TOPDIR)/tools/mknulldeps.sh
NOTE 1: The CodeSourcery toolchain (2009q1) did not work with default optimization
level of -Os (See Make.defs). It will work with -O0, -O1, or -O2, but not with
-Os. I have not seen this problem with current toolchains.
NOTE 2: The devkitARM toolchain includes a version of MSYS make. Make sure that
the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
path or will get the wrong version of make.
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 paths: You will need include/, arch/arm/src/tiva,
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/tiva/tiva_vectors.S.
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 dk-tm4c129x/<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 dk-tm4c129x/<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.

DK-TM4129X 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_CORTEXM4=y
CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
CONFIG_ARCH_CHIP="tiva"
CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
chip:
CONFIG_ARCH_CHIP_TM4C129XNCZAD
CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
hence, the board that supports the particular chip or SoC.
CONFIG_ARCH_BOARD=dk-tm4c129x (for the DK-TM4129X)
CONFIG_ARCH_BOARD_name - For use in C code
CONFIG_ARCH_BOARD_DK_TM4C129X
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=0x00008000 (32Kb)
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.
There are configurations for disabling support for interrupts GPIO ports.
GPIOJ must be disabled because it does not exist on the TM4C129x.
Additional interrupt support can be disabled if desired to reduce memory
footprint.
CONFIG_TIVA_DISABLE_GPIOA_IRQS=n
CONFIG_TIVA_DISABLE_GPIOB_IRQS=n
CONFIG_TIVA_DISABLE_GPIOC_IRQS=n
CONFIG_TIVA_DISABLE_GPIOD_IRQS=n
CONFIG_TIVA_DISABLE_GPIOE_IRQS=n
CONFIG_TIVA_DISABLE_GPIOF_IRQS=n
CONFIG_TIVA_DISABLE_GPIOG_IRQS=n
CONFIG_TIVA_DISABLE_GPIOH_IRQS=n
CONFIG_TIVA_DISABLE_GPIOJ_IRQS=n
CONFIG_TIVA_DISABLE_GPIOK_IRQS=n
CONFIG_TIVA_DISABLE_GPIOL_IRQS=n
CONFIG_TIVA_DISABLE_GPIOM_IRQS=n
CONFIG_TIVA_DISABLE_GPION_IRQS=n
CONFIG_TIVA_DISABLE_GPIOP_IRQS=n
CONFIG_TIVA_DISABLE_GPIOQ_IRQS=n
TM4C129x specific device driver settings
CONFIG_UARTn_SERIAL_CONSOLE - selects the UARTn for the
console and ttys0 (default is the UART0).
CONFIG_UARTn_RXBUFSIZE - Characters are buffered as received.
This specific the size of the receive buffer
CONFIG_UARTn_TXBUFSIZE - Characters are buffered before
being sent. This specific the size of the transmit buffer
CONFIG_UARTn_BAUD - The configure BAUD of the UART. Must be
CONFIG_UARTn_BITS - The number of bits. Must be either 7 or 8.
CONFIG_UARTn_PARTIY - 0=no parity, 1=odd parity, 2=even parity
CONFIG_UARTn_2STOP - Two stop bits
CONFIG_SSI0_DISABLE - Select to disable support for SSI0
CONFIG_SSI1_DISABLE - Select to disable support for SSI1
CONFIG_SSI_POLLWAIT - Select to disable interrupt driven SSI support.
Poll-waiting is recommended if the interrupt rate would be to
high in the interrupt driven case.
CONFIG_SSI_TXLIMIT - Write this many words to the Tx FIFO before
emptying the Rx FIFO. If the SPI frequency is high and this
value is large, then larger values of this setting may cause
Rx FIFO overrun errors. Default: half of the Tx FIFO size (4).
CONFIG_TIVA_ETHERNET - This must be set (along with CONFIG_NET)
to build the Tiva Ethernet driver
CONFIG_TIVA_ETHLEDS - Enable to use Ethernet LEDs on the board.
CONFIG_TIVA_BOARDMAC - If the board-specific logic can provide
a MAC address (via tiva_ethernetmac()), then this should be selected.
CONFIG_TIVA_ETHHDUPLEX - Set to force half duplex operation
CONFIG_TIVA_ETHNOAUTOCRC - Set to suppress auto-CRC generation
CONFIG_TIVA_ETHNOPAD - Set to suppress Tx padding
CONFIG_TIVA_MULTICAST - Set to enable multicast frames
CONFIG_TIVA_PROMISCUOUS - Set to enable promiscuous mode
CONFIG_TIVA_BADCRC - Set to enable bad CRC rejection.
CONFIG_TIVA_DUMPPACKET - Dump each packet received/sent to the console.
Configurations
==============
Each DK-TM4129X configuration is maintained in a
sub-directory and can be selected as follow:
cd tools
./configure.sh dk-tm4c129x/<subdir>
cd -
. ./setenv.sh
Where <subdir> is one of the following:
nsh:
---
Configures the NuttShell (nsh) located at apps/examples/nsh. The
configuration enables the serial VCOM interfaces on UART0. Support for
builtin applications is enabled, but in the base configuration no
builtin applications are selected.
NOTES:
1. This configuration uses the mconf-based configuration tool. To
change this configuration 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. By default, this configuration uses the CodeSourcery toolchain
for Windows and builds under Cygwin (or probably MSYS). That
can easily be reconfigured, of course.
CONFIG_HOST_LINUX=y : Linux (Cygwin under Windows okay too).
CONFIG_ARMV7M_TOOLCHAIN_BUILDROOT=y : Buildroot (arm-nuttx-elf-gcc)
CONFIG_RAW_BINARY=y : Output formats: ELF and raw binary

* All othermethods (including tiva_spiinitialize()) are provided by common

*
* 1. Provide tiva_spiselect() and tiva_spistatus() functions in your
* board-specific logic. This function will perform chip selection and
* status operations using GPIOs in the way your board is configured.
* 2. Add a call to tiva_spiinitialize() in your low level initialization
* logic
* 3. The handle returned by tiva_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).
