The TWR-K60N512 features two expansion card-edge connectors that interface
|
|
to the Primary and Secondary Elevator boards in a Tower system. The Primary
|
|
Connector (comprised of sides A and B) is utilized by the TWR-K60N512 while
|
|
the Secondary Connector (comprised of sides C and D) only makes connections
|
|
to the GND pins.

TWR-SER Serial Board Connection
|
|
===============================
|
|
|
|
The serial board connects into the tower and then maps to the tower pins to
|
|
yet other functions (see TWR-SER.pdf).
|
|
|
|
For the serial port, the following jumpers are required:
|
|
|
|
J15: 1-2 (default)
|
|
J17: 1-2 (default)
|
|
J18: 1-2 (default)
|
|
J19: 1-2 (default)
|
|
|
|
The two connections map as follows:
|
|
|
|
A41 RXD0 - Not connected
|
|
A42 TXD0 - Not connected
|
|
A43 RXD1 - ELE_RXD (connects indirectory to DB-9 connector J8)
|
|
A44 TXD1 - ELE_TXD (connects indirectory to DB-9 connector J8)
|
|
|
|
Finally, we can conclude that:
|
|
|
|
UART4 (PTE24/25) is not connected, and
|
|
UART3 (PTC16/17) is associated with the DB9 connector
|
|
|
|
NOTE: UART5 is associated with OSJTAG bridge and may also be usable.
|
|
|
|
LEDs
|
|
====
|
|
|
|
The TWR-K60N100 board has four LEDs labeled D2..D4 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 LED1* LED2 LED3 LED4
|
|
------------------- ----------------------- ------- ------- ------- ------
|
|
LED_STARTED NuttX has been started ON OFF OFF OFF
|
|
LED_HEAPALLOCATE Heap has been allocated OFF ON OFF OFF
|
|
LED_IRQSENABLED Interrupts enabled ON ON OFF OFF
|
|
LED_STACKCREATED Idle stack created OFF OFF ON OFF
|
|
LED_INIRQ In an interrupt** ON N/C N/C OFF
|
|
LED_SIGNAL In a signal handler*** N/C ON N/C OFF
|
|
LED_ASSERTION An assertion failed ON ON N/C OFF
|
|
LED_PANIC The system has crashed N/C N/C N/C ON
|
|
LED_IDLE STM32 is is sleep mode (Optional, not used)
|
|
|
|
* If LED1, LED2, LED3 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 LED3 ON and LED1 faintly glowing. This faint glow
|
|
is because of timer interupts that result in the LED being illuminated
|
|
on a small proportion of the time.
|
|
*** LED2 may also flicker normally if signals are processed.
|
|
|
|
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 CodeSourcery GNU toolchain,
|
|
2. The devkitARM GNU toolchain,
|
|
3. The NuttX buildroot Toolchain (see below).
|
|
|
|
All testing has been conducted using the CodeSourcery Windows toolchain. To
|
|
use the devkitARM or the NuttX GNU toolchain, you simply need to change the
|
|
the following configuration options to your .config (or defconfig) file:
|
|
|
|
CONFIG_KINETIS_CODESOURCERYW=y : CodeSourcery under Windows
|
|
CONFIG_KINETIS_CODESOURCERYL=y : CodeSourcery under Linux
|
|
CONFIG_KINETIS_DEVKITARM=y : devkitARM under Windows
|
|
CONFIG_KINETIS_BUILDROOT=y : NuttX buildroot under Linux or Cygwin (default)
|
|
|
|
If you are not using CONFIG_KINETIS_BUILDROOT, 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) and devkitARM 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 not 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.
|
|
|
|
Support has been added for making dependencies with the windows-native toolchains.
|
|
That support can be enabled by modifying your Make.defs file as follows:
|
|
|
|
- MKDEP = $(TOPDIR)/tools/mknulldeps.sh
|
|
+ MKDEP = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
|
|
|
|
If you have problems with the dependency build (for example, if you are not
|
|
building on C:), then you may need to modify tools/mkdeps.sh
|
|
|
|
NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
|
|
level of -Os (See Make.defs). It will work with -O0, -O1, or -O2, but not with
|
|
-Os.
|
|
|
|
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 pathes: You will need include/, arch/arm/src/k40,
|
|
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/kinetis/k40_vectors.S.
|
|
|
|
NuttX 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-M4 GCC toolchain (if
|
|
different from the default in your PATH variable).
|
|
|
|
If you have no Cortex-M4 toolchain, one can be downloaded from the NuttX
|
|
SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
|
|
This GNU toolchain builds and executes in the Linux or Cygwin environment.
|
|
|
|
NOTE: The NuttX toolchain is an OABI toolchain (vs. the more common EABI)
|
|
and does not include optimizations for Cortex-M4 (ARMv7E-M).
|
|
|
|
1. You must have already configured Nuttx in <some-dir>/nuttx.
|
|
|
|
cd tools
|
|
./configure.sh twr-k60n512/<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-4.3.3 .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
|
|
detailed PLUS some special instructions that you will need to follow if you are
|
|
building a Cortex-M4 toolchain for Cygwin under Windows.
|
|
|
|
TWR-K60N512-specific Configuration Options

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.

|
Each TWR-K60N512 configuration is maintained in a sudirectory and
|
|
can be selected as follow:
|
|
|
|
cd tools
|
|
./configure.sh twr-k60n512/<subdir>
|
|
cd -
|
|
. ./setenv.sh
|
|
|
|
Where <subdir> is one of the following:
|
|
|
|
ostest:
