LEDs
====
All pulled high and can be illuminated by driving the output to low
There are four LEDs on the ViewTool STM32F103/F107 board that can be controlled
by software: LED1 through LED4. All pulled high and can be illuminated by
driving the output to low
LED1 PA6
LED2 PA7
LED3 PB12
LED4 PB13
These LEDs are not used by the board port unless CONFIG_ARCH_LEDS is
defined. In that case, the usage by the board port is defined in
include/board.h and src/stm32_leds.c. The LEDs are used to encode OS-related
events as follows:
SYMBOL Meaning LED state
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 N/C N/C N/C Soft glow
LED_SIGNAL In a signal handler N/C N/C N/C Soft glow
LED_ASSERTION An assertion failed N/C N/C N/C Soft glow
LED_PANIC The system has crashed N/C N/C N/C 2Hz Flashing
LED_IDLE MCU is is sleep mode Not used
After booting, LED1-3 are not longer used by the system and can be used for
other purposes by the application (Of course, all LEDs are available to the
application if CONFIG_ARCH_LEDS is not defined.

Toolchains
==========
NOTE about Windows 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
Configurations
==============
Information Common to All Configurations
----------------------------------------
Each SAM3U-EK configuration is maintained in a sub-directory and
can be selected as follow:
cd tools
./configure.sh viewtool-stm32f107/<subdir>
cd -
. ./setenv.sh
Before sourcing the setenv.sh file above, you should examine it and perform
edits as necessary so that TOOLCHAIN_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 USART1.
3. Unless otherwise stated, the configurations are setup for
Cygwin under Windows:
Build Setup:
CONFIG_HOST_WINDOWS=y : Windows operating system
CONFIG_WINDOWS_CYGWIN=y : POSIX environment under windows
4. All of these configurations use the Code Sourcery for Windows 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:
System Type -> Toolchain:
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : GNU EABI toolchain for windows
The setenv.sh file is available for you to use to set the 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:
This configuration directory provide the basuic NuttShell (NSH).
NOTES:
1. This configuration uses the default USART1 serial console. That
is easily changed by reconfiguring to (1) enable a different
serial peripheral, and (2) selecting that serial peripheral as
the console device.
2. By default, this configuration is set up to build on Windows
under either a Cygwin or MSYS environment using a recent, Windows-
native, generic ARM EABI GCC toolchain (such as the CodeSourcery
toolchain). Both the build environment and the toolchain
selection can easily be changed by reconfiguring:
CONFIG_HOST_WINDOWS=y : Windows operating system
CONFIG_WINDOWS_CYGWIN=y : POSIX environment under windows
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery for Windows
