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.
GNU Toolchain Options
=====================
As of this writing, all testing has been performed using the NuttX buildroot
toolchain described below. I have also verified the build using the
CodeSourcery GCC toolchain for windows. Most any contemporary EABI GCC
toolchain should work will a little tinkering.
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-M3 GCC toolchain (if
different from the default in your PATH variable).
If you have no Cortex-M0 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 freedom-kl25z/<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/cortexm0-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.
LEDs
====
The NuTiny has a single green LED that can be controlled from sofware.
This LED is connected to PIN17. It is pulled high so a low value will
illuminate the LED.
If CONFIG_ARCH_LEDs is defined, then NuttX will control the LED on board the
NuTiny. The following definitions describe how NuttX controls the LEDs:
SYMBOL Meaning LED state
Initially all LED is OFF
------------------- ----------------------- ------------- ------------
LED_STARTED NuttX has been started LED ON
LED_HEAPALLOCATE Heap has been allocated LED ON
LED_IRQSENABLED Interrupts enabled LED ON
LED_STACKCREATED Idle stack created LED ON
LED_INIRQ In an interrupt LED should glow
LED_SIGNAL In a signal handler LED might glow
LED_ASSERTION An assertion failed LED ON while handling the assertion
LED_PANIC The system has crashed LED Blinking at 2Hz
LED_IDLE K25Z1XX is in sleep mode (Optional, not used)
Serial Console
==============
As with most NuttX configurations, the Freedom K25Z configurations
depend on having a serial console to interact with the software. The
Freedom K25Z, however, has not on-board RS-232 drivers so will be
necessary to connect the Freedom K25Z UART pins to an external
RS-232 driver board or TTL-to-Serial USB adaptor.
By default UART1 is used as the serial console on these boards. K25Z120LE3AN
is provided as an LQFP48 package and, for this case, the UART1 RX signal
(RXD1) is on PB.4, pin 8, and the TX signal (TXD1) is on PB.5, pin 9.
These pins are available on the Freedom K25Z JP5.
NOTE: The TX vs RX labeling may be confusing. On one RS-232 driver board,
I had to connect the K25Z120 TXD0 pin to the driver boards RXD pin. How
confusing!
UART0 is an alternative that can be selected by modifying the default
configuation. UART0 RX (RXD0) is on PB.0, pin 17, and the TX signal (TXD0)
is on PB.1, pin 18. These pins are available on the Freedom K25Z JP1.
NOTE: PB.0, pin 17, is also used to control the user LED on board (labeled
"IO"). CONFIG_ARCH_LED should not be selected if UART0 is used.
The K25Z120LE3AN does not support UART2.
Debugging
=========
The Freedom K25Z includes a built-in NuLink debugger. Unfortunately,
full debug support is available only with the Keil and IAR toolchains.
There is, however, a free program called ICP (In-Circuit Programmer). It
can be used to burn programs into FLASH (aka APROM).
The ICP program can also be used to burn an ISP program into LDROM. The
ISP (In-System Programmer) is available free from the Nuvton website.
Then NuttX build does not set the configuration words at 0x0030000-0x00300004.
You should uncheck the Config box when burning APROM or the previous contents
of the configuration words will be erased.
NuTiny-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_CORTEXM0=y
CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
CONFIG_ARCH_CHIP=kl
CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
chip:
CONFIG_ARCH_CHIP_K25Z120LE3AN=y
CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
hence, the board that supports the particular chip or SoC.
CONFIG_ARCH_BOARD=freedom-kl25z (for the Freescale FRDM-KL25Z development board)
CONFIG_ARCH_BOARD_name - For use in C code
CONFIG_ARCH_BOARD_FREEDOM_K25Z128=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_DRAM_SIZE - Describes the installed DRAM (SRAM in this case):
CONFIG_DRAM_SIZE=16384 (16Kb)
CONFIG_DRAM_START - The start address of installed DRAM
CONFIG_DRAM_START=0x20000000
CONFIG_ARCH_IRQPRIO - The Cortex-M0 supports interrupt prioritization
CONFIG_ARCH_IRQPRIO=y
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.
Individual subsystems can be enabled as follows. These settings are for
all of the K25Z100/120 line and may not be available for the K25Z120LE3AN
in particular:

Configurations
==============
Each FREEDOM-KL25Z configuration is maintained in a sub-directory and
can be selected as follow:
cd tools
./configure.sh freedom-kl25z/<subdir>
cd -
. ./setenv.sh
If this is a Windows native build, then configure.bat should be used
instead of configure.sh:
configure.bat freedom-kl25z\<subdir>
Where <subdir> is one of the following:
ostest:
------
This configuration directory, performs a simple OS test using
apps/examples/ostest.
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. Default toolchain:
CONFIG_HOST_WINDOWS=y : Builds under Windows
CONFIG_WINDOWS_CYGWIN=y : Using Cygwin
CONFIG_ARMV6M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery for Windows
3. Serial Console. A serial console is required to see the OS test
output. The serial console is configured on UART1 which is available
on JP5:
UART1 RX signal (RXD1) is on PB.4, pin 8, and
UART1 TX signal (TXD1) is on PB.5, pin 9.
nsh:
---
Configures the NuttShell (nsh) located at apps/examples/nsh. The
Configuration enables the serial interfaces on UART1. Support for
builtin applications is disabled.
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_WINDOWS=y : Builds under Windows
CONFIG_WINDOWS_CYGWIN=y : Using Cygwin
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery for Windows
3. Serial Console. A serial console is necessary to interrupt with
NSH. The serial console is configured on UART1 which is available
on JP5:
UART1 RX signal (RXD1) is on PB.4, pin 8, and
UART1 TX signal (TXD1) is on PB.5, pin 9.
It is possible to configure NSH to use a USB serial console instead
of an RS-232 serial console. However, that configuration has not
been impelmented as of this writing.
4. Memory Usage. The size command gives us the static memory usage.
This is what I get:
$ size nuttx
text data bss dec hex filename
35037 106 1092 36235 8d8b nuttx
And we can get the runtime memory usage from the NSH free command:
NuttShell (NSH) NuttX-6.25
nsh> free
total used free largest
Mem: 14160 3944 10216 10216
nsh>
Summary:
- This slightly tuned NSH example uses 34.2KB of FLASH leaving 93.8KB
of FLASH (72%) free from additional application development.
I did not do all of the arithmetic, but it appears to me that of this
34+KB of FLASH usage, probably 20-30% of the FLASH is used by libgcc!
libgcc has gotten very fat!
- Static SRAM usage is about 1.2KB (<4%).
- At run time, 10.0KB of SRAM (62%) is still available for additional
applications. Most of the memory used at runtime is allocated I/O
buffers and the stack for the NSH main thread (1.5KB).
There is probably enough free memroy to support 3 or 4 application
threads in addition to NSH.
