DFU and JTAG
|
|
============
|
|
|
|
Enbling Support for the DFU Bootloader
|
|
--------------------------------------
|
|
The linker files in these projects can be configured to indicate that you
|
|
will be loading code using STMicro built-in USB Device Firmware Upgrade (DFU)
|
|
loader or via some JTAG emulator. You can specify the DFU bootloader by
|
|
adding the following line:
|
|
|
|
CONFIG_STM32_DFU=y
|
|
|
|
to your .config file. Most of the configurations in this directory are set
|
|
up to use the DFU loader.
|
|
|
|
If CONFIG_STM32_DFU is defined, the code will not be positioned at the beginning
|
|
of FLASH (0x08000000) but will be offset to 0x08003000. This offset is needed
|
|
to make space for the DFU loader and 0x08003000 is where the DFU loader expects
|
|
to find new applications at boot time. If you need to change that origin for some
|
|
other bootloader, you will need to edit the file(s) ld.script.dfu for the
|
|
configuration.
|
|
|
|
The DFU SE PC-based software is available from the STMicro website,
|
|
http://www.st.com. General usage instructions:
|
|
|
|
1. Convert the NuttX Intel Hex file (nuttx.hex) into a special DFU
|
|
file (nuttx.dfu)... see below for details.
|
|
2. Connect the STM3210E-EVAL board to your computer using a USB
|
|
cable.
|
|
3. Start the DFU loader on the STM3210E-EVAL board. You do this by
|
|
resetting the board while holding the "Key" button. Windows should
|
|
recognize that the DFU loader has been installed.
|
|
3. Run the DFU SE program to load nuttx.dfu into FLASH.
|
|
|
|
What if the DFU loader is not in FLASH? The loader code is available
|
|
inside of the Demo directory of the USBLib ZIP file that can be downloaded
|
|
from the STMicro Website. You can build it using RIDE (or other toolchains);
|
|
you will need a JTAG emulator to burn it into FLASH the first time.
|
|
|
|
In order to use STMicro's built-in DFU loader, you will have to get
|
|
the NuttX binary into a special format with a .dfu extension. The
|
|
DFU SE PC_based software installation includes a file "DFU File Manager"
|
|
conversion program that a file in Intel Hex format to the special DFU
|
|
format. When you successfully build NuttX, you will find a file called
|
|
nutt.hex in the top-level directory. That is the file that you should
|
|
provide to the DFU File Manager. You will end up with a file called
|
|
nuttx.dfu that you can use with the STMicro DFU SE program.
|
|
|
|
Enabling JTAG
|
|
-------------
|
|
If you are not using the DFU, then you will probably also need to enable
|
|
JTAG support. By default, all JTAG support is disabled but there NuttX
|
|
configuration options to enable JTAG in various different ways.
|
|
|
|
These configurations effect the setting of the SWJ_CFG[2:0] bits in the AFIO
|
|
MAPR register. These bits are used to configure the SWJ and trace alternate
|
|
function I/Os. The SWJ (SerialWire JTAG) supports JTAG or SWD access to the
|
|
Cortex debug port. The default state in this port is for all JTAG support
|
|
to be disabled.
|
|
|
|
CONFIG_STM32_JTAG_FULL_ENABLE - sets SWJ_CFG[2:0] to 000 which enables full
|
|
SWJ (JTAG-DP + SW-DP)
|
|
|
|
CONFIG_STM32_JTAG_NOJNTRST_ENABLE - sets SWJ_CFG[2:0] to 001 which enable
|
|
full SWJ (JTAG-DP + SW-DP) but without JNTRST.
|
|
|
|
CONFIG_STM32_JTAG_SW_ENABLE - sets SWJ_CFG[2:0] to 010 which would set JTAG-DP
|
|
disabled and SW-DP enabled.
|
|
|
|
The default setting (none of the above defined) is SWJ_CFG[2:0] set to 100
|
|
which disable JTAG-DP and SW-DP.
|
|
|
|
OpenOCD
|
|
=======
|
|
|
|
I have also used OpenOCD with the STM3210E-EVAL. In this case, I used
|
|
the Olimex USB ARM OCD. See the script in boards/arm/stm32/stm3210e-eval/tools/oocd.sh
|
|
for more information. Using the script:
|
|
|
|
1) Start the OpenOCD GDB server
|
|
|
|
cd <nuttx-build-directory>
|
|
boards/arm/stm32/stm3210e-eval/tools/oocd.sh $PWD
|
|
|
|
2) Load Nuttx
|
|
|
|
cd <nuttx-built-directory>
|
|
arm-none-eabi-gdb nuttx
|
|
gdb> target remote localhost:3333
|
|
gdb> mon reset
|
|
gdb> mon halt
|
|
gdb> load nuttx
|
|
|
|
3) Running NuttX
|
|
|
|
gdb> mon reset
|
|
gdb> c
|
|
|
|
LEDs
|
|
====
|
|
|
|
The STM3210E-EVAL board has four LEDs labeled LD1, LD2, LD3 and LD4 on the
|
|
board. 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/up_leds.c. The LEDs are used to encode OS-related
|
|
events 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 interrupts that result in the LED being illuminated
|
|
on a small proportion of the time.
|
|
*** LED2 may also flicker normally if signals are processed.
|
|
|
|
Temperature Sensor
|
|
==================
|
|
|
|
LM-75 Temperature Sensor Driver
|
|
-------------------------------
|
|
Support for the on-board LM-75 temperature sensor is available. This
|
|
support has been verified, but has not been included in any of the
|
|
available the configurations. To set up the temperature sensor, add the
|
|
following to the NuttX configuration file
|
|
|
|
Drivers -> Sensors
|
|
CONFIG_SENSORS_LM75=y
|
|
CONFIG_LM75_I2C=y
|
|
|
|
Then you can implement logic like the following to use the temperature
|
|
sensor:
|
|
|
|
#include <nuttx/sensors/lm75.h>
|
|
#include <arch/board/board.h>
|
|
|
|
ret = stm32_lm75initialize("/dev/temp"); /* Register the temperature sensor */
|
|
fd = open("/dev/temp", O_RDONLY); /* Open the temperature sensor device */
|
|
ret = ioctl(fd, SNIOC_FAHRENHEIT, 0); /* Select Fahrenheit */
|
|
bytesread = read(fd, buffer, 8*sizeof(b16_t)); /* Read temperature samples */
|
|
|
|
More complex temperature sensor operations are also available. See the
|
|
IOCTL commands enumerated in include/nuttx/sensors/lm75.h. Also read the
|
|
descriptions of the stm32_lm75initialize() and stm32_lm75attach()
|
|
interfaces in the arch/board/board.h file (sames as
|
|
boards/arm/stm32/stm3210e-eval/include/board.h).
|
|
|
|
NSH Command Line Application
|
|
----------------------------
|
|
There is a tiny NSH command line application at examples/system/lm75 that
|
|
will read the current temperature from an LM75 compatible temperature sensor
|
|
and print the temperature on stdout in either units of degrees Fahrenheit or
|
|
Centigrade. This tiny command line application is enabled with the following
|
|
configuration options:
|
|
|
|
Library
|
|
CONFIG_LIBM=y
|
|
CONFIG_LIBC_FLOATINGPOINT=y
|
|
|
|
Applications -> NSH Library
|
|
CONFIG_NSH_ARCHINIT=y
|
|
|
|
Applications -> System Add-Ons
|
|
CONFIG_SYSTEM_LM75=y
|
|
CONFIG_SYSTEM_LM75_DEVNAME="/dev/temp"
|
|
CONFIG_SYSTEM_LM75_FAHRENHEIT=y (or CENTIGRADE)
|
|
CONFIG_SYSTEM_LM75_STACKSIZE=1024
|
|
CONFIG_SYSTEM_LM75_PRIORITY=100
|
|
|
|
RTC
|
|
===
|
|
|
|
The STM32 RTC may configured using the following settings.
|
|
|
|
CONFIG_RTC - Enables general support for a hardware RTC. Specific
|
|
architectures may require other specific settings.
|
|
CONFIG_RTC_HIRES - The typical RTC keeps time to resolution of 1
|
|
second, usually supporting a 32-bit time_t value. In this case,
|
|
the RTC is used to "seed" the normal NuttX timer and the
|
|
NuttX timer provides for higher resolution time. If CONFIG_RTC_HIRES
|
|
is enabled in the NuttX configuration, then the RTC provides higher
|
|
resolution time and completely replaces the system timer for purpose of
|
|
date and time.
|
|
CONFIG_RTC_FREQUENCY - If CONFIG_RTC_HIRES is defined, then the
|
|
frequency of the high resolution RTC must be provided. If CONFIG_RTC_HIRES
|
|
is not defined, CONFIG_RTC_FREQUENCY is assumed to be one.
|
|
CONFIG_RTC_ALARM - Enable if the RTC hardware supports setting of an alarm.
|
|
A callback function will be executed when the alarm goes off.
|
|
|
|
In hi-res mode, the STM32 RTC operates only at 16384Hz. Overflow interrupts
|
|
are handled when the 32-bit RTC counter overflows every 3 days and 43 minutes.
|
|
A BKP register is incremented on each overflow interrupt creating, effectively,
|
|
a 48-bit RTC counter.
|
|
|
|
In the lo-res mode, the RTC operates at 1Hz. Overflow interrupts are not handled
|
|
(because the next overflow is not expected until the year 2106).
|
|
|
|
WARNING: Overflow interrupts are lost whenever the STM32 is powered down. The
|
|
overflow interrupt may be lost even if the STM32 is powered down only momentarily.
|
|
Therefore hi-res solution is only useful in systems where the power is always on.
|
|
|
|
FSMC SRAM
|
|
=========
|
|
|
|
The 8-Mbit SRAM is connected to the STM32 at PG10 which will be FSMC_NE3, Bank1
|
|
SRAM3. This memory will appear at address 0x68000000.
|
|
|
|
The on-board SRAM can be configured by setting
|
|
|
|
CONFIG_STM32_FSMC=y : Enables the FSMC
|
|
CONFIG_STM32_EXTERNAL_RAM=y : Enable external SRAM support
|
|
CONFIG_HEAP2_BASE=0x68000000 : SRAM will be located at 0x680000000
|
|
CONFIG_HEAP2_SIZE=1048576 : The size of the SRAM is 1Mbyte
|
|
CONFIG_MM_REGIONS=2 : There will be two memory regions
|
|
: in the heap
|
|
|
|

Timer and I2C devices may need to the following to force power to be applied
|
|
unconditionally at power up. (Otherwise, the device is powered when it is
|
|
initialized).
|
|
|
|
CONFIG_STM32_FORCEPOWER
|
|
|
|
Timer devices may be used for different purposes. One special purpose is
|
|
to generate modulated outputs for such things as motor control. If CONFIG_STM32_TIMn
|
|
is defined (as above) then the following may also be defined to indicate that
|
|
the timer is intended to be used for pulsed output modulation, ADC conversion,
|
|
or DAC conversion. Note that ADC/DAC require two definition: Not only do you have
|
|
to assign the timer (n) for used by the ADC or DAC, but then you also have to
|
|
configure which ADC or DAC (m) it is assigned to.
|
|
|
|
CONFIG_STM32_TIMn_PWM Reserve timer n for use by PWM, n=1,..,8
|
|
CONFIG_STM32_TIMn_ADC Reserve timer n for use by ADC, n=1,..,8
|
|
CONFIG_STM32_TIMn_ADCm Reserve timer n to trigger ADCm, n=1,..,8, m=1,..,3
|
|
CONFIG_STM32_TIMn_DAC Reserve timer n for use by DAC, n=1,..,8
|
|
CONFIG_STM32_TIMn_DACm Reserve timer n to trigger DACm, n=1,..,8, m=1,..,2
|
|
|
|
For each timer that is enabled for PWM usage, we need the following additional
|
|
configuration settings:
|
|
|
|
CONFIG_STM32_TIMx_CHANNEL - Specifies the timer output channel {1,..,4}
|
|
|
|
NOTE: The STM32 timers are each capable of generating different signals on
|
|
each of the four channels with different duty cycles. That capability is
|
|
not supported by this driver: Only one output channel per timer.
|
|
|
|
Alternate pin mappings. The STM3210E-EVAL board requires only CAN1 remapping
|
|
On the STM3210E-EVAL board pin PB9 is wired as TX and pin PB8 is wired as RX.
|
|
Which then makes the proper connection through the CAN transceiver SN65HVD230
|
|
out to the CAN D-type 9-pn male connector where pin 2 is CANL and pin 7 is CANH.

|
|
Default: 7
|
|
CONFIG_STM32_CAN_REGDEBUG - If CONFIG_DEBUG_FEATURES is set, this will generate an
|
|
dump of all CAN registers.
|
|
|
|
STM3210E-EVAL LCD Hardware Configuration
|
|
|
|
CONFIG_LCD_LANDSCAPE - Define for 320x240 display "landscape"
|
|
support. Default is this 320x240 "landscape" orientation
|
|
(this setting is informative only... not used).
|
|
CONFIG_LCD_PORTRAIT - Define for 240x320 display "portrait"
|
|
orientation support. In this orientation, the STM3210E-EVAL's
|
|
LCD ribbon cable is at the bottom of the display. Default is
|
|
320x240 "landscape" orientation.
|
|
CONFIG_LCD_RPORTRAIT - Define for 240x320 display "reverse
|
|
portrait" orientation support. In this orientation, the
|
|
STM3210E-EVAL's LCD ribbon cable is at the top of the display.
|
|
Default is 320x240 "landscape" orientation.
|
|
CONFIG_STM3210E_LCD_BACKLIGHT - Define to support a backlight.
|
|
CONFIG_STM3210E_LCD_PWM - If CONFIG_STM32_TIM1 is also defined, then an
|
|
adjustable backlight will be provided using timer 1 to generate
|
|
various pulse widthes. The granularity of the settings is
|
|
determined by CONFIG_LCD_MAXPOWER. If CONFIG_STM3210E_LCD_PWM (or
|
|
CONFIG_STM32_TIM1) is not defined, then a simple on/off backlight
|
|
is provided.
|
|
CONFIG_STM3210E_LCD_RDSHIFT - When reading 16-bit gram data, there appears
|
|
to be a shift in the returned data. This value fixes the offset.
|
|
Default 5.
|
|
|
|
The LCD driver dynamically selects the LCD based on the reported LCD
|
|
ID value. However, code size can be reduced by suppressing support for
|
|
individual LCDs using:
|
|
|
|
CONFIG_STM3210E_AM240320_DISABLE
|
|
CONFIG_STM3210E_SPFD5408B_DISABLE
|
|
CONFIG_STM3210E_R61580_DISABLE
|
|
|

Configurations
|
|
==============
|
|
|
|
Each STM3210E-EVAL configuration is maintained in a sub-directory and
|
|
can be selected as follow:
|
|
|
|
tools/configure.sh stm3210e-eval:<subdir>
|
|
|
|
Where <subdir> is one of the following:
|
|
|
|
composite
|
|
---------
|
|
|
|
This configuration exercises a composite USB interface consisting
|
|
of a CDC/ACM device and a USB mass storage device. This configuration
|
|
uses apps/system/composite.
|
|
|
|
nsh and nsh2:

|
|
|
|
(1) You will probably need to modify PATH environment variable to
|
|
to include the correct path to the binaries for whichever
|
|
toolchain you may use.
|
|
(2) Since DfuSe is assumed, this configuration may only work under
|
|
Cygwin without modification.
|
|
(3) When any other device other than /dev/console is used for a user
|
|
interface, (1) linefeeds (\n) will not be expanded to carriage return
|
|
/ linefeeds \r\n). You will need to configure your terminal program
|
|
to account for this. And (2) input is not automatically echoed so
|
|
you will have to turn local echo on.
|
|
(4) Microsoft holds several patents related to the design of
|
|
long file names in the FAT file system. Please refer to the
|
|
details in the top-level COPYING file. Please do not use FAT
|
|
long file name unless you are familiar with these patent issues.
|
|
(5) When built as an NSH add-on command (CONFIG_NSH_BUILTIN_APPS=y),
|
|
Caution should be used to assure that the SD drive is not in use when
|
|
the USB storage device is configured. Specifically, the SD driver
|
|
should be unmounted like:
|
|
|
|
nsh> mount -t vfat /dev/mmcsd0 /mnt/sdcard # Card is mounted in NSH
|
|
...
|
|
nsh> umount /mnd/sdcard # Unmount before connecting USB!!!
|
|
nsh> msconn # Connect the USB storage device
|
|
...
|
|
nsh> msdis # Disconnect USB storate device
|
|
nsh> mount -t vfat /dev/mmcsd0 /mnt/sdcard # Restore the mount
|
|
|
|
Failure to do this could result in corruption of the SD card format.
|
|
|
|
1. Both configurations use the mconf-based configuration tool. To
|
|
change these configurations using that tool, you should:
|
|
|
|
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
|
see additional README.txt files in the NuttX tools repository.
|
|
|
|
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
|
reconfiguration process.
|
|
|
|
2. The nsh2 contains support for some built-in applications that can be
|
|
enabled by make some additional minor changes:
|
|
|
|
a. examples/can. The CAN test example can be enabled by changing the
|
|
following settings in nsh2/defconfig:
|
|
|
|
CONFIG_CAN=y : Enable CAN "upper-half" driver support
|
|
CONFIG_STM32_CAN1=y : Enable STM32 CAN1 "lower-half" driver support
|
|
|
|
The default CAN settings may need to change in your board board
|
|
configuration:
|
|
|
|
CONFIG_CAN_EXTID=y : Support extended IDs
|
|
CONFIG_STM32_CAN1_BAUD=250000 : Bit rate: 250 KHz
|
|
CONFIG_STM32_CAN_TSEG1=12 : 80% sample point
|
|
CONFIG_STM32_CAN_TSEG2=3
|
|
nx:

|
---
|
|
An example using the NuttX graphics system (NX). This example
|
|
focuses on general window controls, movement, mouse and keyboard
|
|
input.
|
|
|
|
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery under Windows
|
|
CONFIG_LCD_RPORTRAIT=y : 240x320 reverse portrait
|
|
|
|
NOTES:
|
|
|
|
1. This configuration uses the mconf-based configuration tool. To
|
|
change this configurations using that tool, you should:
|

|
|
|
|
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
|
reconfiguration process.
|
|
|
|
2. If you configured the multi-used NX server (which is disabled
|
|
by default), then you would also need:
|
|
|
|
CONFIG_EXAMPLES_NX_CLIENTPRIO=80
|
|
CONFIG_EXAMPLES_NX_NOTIFYSIGNO=4
|
|
CONFIG_EXAMPLES_NX_SERVERPRIO=120
|
|
CONFIG_EXAMPLES_NX_STACKSIZE=2048
|
|
|
|
3. This example provides a framework for a number of other standalone
|
|
graphics tests.
|
|
|
|
a. apps/examples/nxlines: The NXLINES graphic example illustrates
|
|
drawing of fat lines in various orientations. You can modify
|
|
this configuration so to support the NXLINES example by making
|
|
the following modifications to the NuttX configuration file:
|
|
|
|
Provide the new start-up entry point:
|
|
|
|
CONFIG_USER_ENTRYPOINT="nxlines_main"
|
|
|
|
Disable apps/examples/nx:
|
|
|
|
CONFIG_EXAMPLES_NX=n
|
|
|
|
Enable and configure apps/nxlines/nxlines:
|
|
|
|
CONFIG_EXAMPLES_NXLINES=y
|
|
CONFIG_EXAMPLES_NXLINES_VPLANE=0
|
|
CONFIG_EXAMPLES_NXLINES_DEVNO=0
|
|
CONFIG_EXAMPLES_NXLINES_DEFAULT_COLORS=n
|
|
CONFIG_EXAMPLES_NXLINES_BGCOLOR=0x0320
|
|
CONFIG_EXAMPLES_NXLINES_LINEWIDTH=16
|
|
CONFIG_EXAMPLES_NXLINES_LINECOLOR=0xffe0
|
|
CONFIG_EXAMPLES_NXLINES_BORDERWIDTH=4
|
|
CONFIG_EXAMPLES_NXLINES_BORDERCOLOR=0xffe0
|
|
CONFIG_EXAMPLES_NXLINES_CIRCLECOLOR=0xf7bb
|
|
CONFIG_EXAMPLES_NXLINES_BPP=16
|
|
CONFIG_EXAMPLES_NXLINES_EXTERNINIT=n
|
|
|
|
b. apps/examples/nxtext: Another example using the NuttX graphics
|
|
system (NX). This example focuses on placing text on the
|
|
background while pop-up windows occur. Text should continue to
|
|
update normally with or without the popup windows present.
|
|
|
|
You can modify this configuration so to support the NXLINES
|
|
example by making the following modifications to the NuttX
|
|
configuration file:
|
|
|
|
Provide the new start-up entry point:
|
|
|
|
CONFIG_USER_ENTRYPOINT="nxtext_main"
|
|
|
|
Disable apps/examples/nx:
|
|
|
|
CONFIG_EXAMPLES_NX=n
|
|
|
|
Enable an NX font:
|
|
|
|
CONFIG_NXFONT_SERIF22X28B=y
|
|
|
|
Enable and configure apps/nxlines/nxtext:
|
|
|
|
CONFIG_EXAMPLES_NXTEXT=y
|
|
CONFIG_EXAMPLES_NXTEXT_VPLANE=0
|
|
CONFIG_EXAMPLES_NXTEXT_DEVNO=0
|
|
CONFIG_EXAMPLES_NXTEXT_BPP=16
|
|
CONFIG_EXAMPLES_NXTEXT_BMCACHE=512
|
|
CONFIG_EXAMPLES_NXTEXT_GLCACHE=16
|
|
CONFIG_EXAMPLES_NXTEXT_DEFAULT_COLORS=n
|
|
CONFIG_EXAMPLES_NXTEXT_BGCOLOR=0x0011
|
|
CONFIG_EXAMPLES_NXTEXT_BGFONTCOLOR=0xffdf
|
|
CONFIG_EXAMPLES_NXTEXT_PUCOLOR=0xfd20
|
|
CONFIG_EXAMPLES_NXTEXT_PUFONTCOLOR=0x001f
|
|
CONFIG_EXAMPLES_NXTEXT_DEFAULT_FONT=n
|
|
CONFIG_EXAMPLES_NXTEXT_BGFONTID=11
|
|
CONFIG_EXAMPLES_NXTEXT_PUFONTID=1
|
|
CONFIG_EXAMPLES_NXTEXT_EXTERNINIT=n
|
|
|
|
If you configured the multi-used NX server (which is disabled
|
|
by default), then you would also need:
|
|
|
|
CONFIG_EXAMPLES_NXTEXT_STACKSIZE=2048
|
|
CONFIG_EXAMPLES_NXTEXT_CLIENTPRIO=80
|
|
CONFIG_EXAMPLES_NXTEXT_SERVERPRIO=120
|
|
CONFIG_EXAMPLES_NXTEXT_NOTIFYSIGNO=4
|
|
|
|
c. Others could be similar configured: apps/examples/nxhello,
|
|
nximage, ...
|
|
|
|
4. The nsh configuration was used to verify the discrete joystick
|
|
(DJoystick driver). If you would like to duplicate this test, below
|
|
are the configuration changes needed to setup the DJoystick driver
|
|
(see nuttx/drivers/input/djoystick.c) and the DJoystick test (see
|
|
apps/examples/djoystick):
|
|
|
|
Pre-requisites:
|
|
|
|
CONFIG_BUILTIN=y # Enable support for built-in applications
|
|
CONFIG_NSH_BUILTIN_APPS=y # Enable NSH built-in applications
|
|
|
|
Enable the DJoystick driver:
|
|
|
|
CONFIG_INPUT=y # Enable input driver support
|
|
CONFIG_DJOYSTICK=y # Enable the joystick drivers
|
|
# (default parameters should be okay)
|
|
Enable the DJoystick Example:
|
|
|
|
CONFIG_EXAMPLES_DJOYSTICK=y # Enable the DJoystick example
|
|
CONFIG_EXAMPLES_DJOYSTICK_DEVNAME="/dev/djoy0"
|
|
CONFIG_EXAMPLES_DJOYSTICK_SIGNO=13
|
|
|
|
When running the configuration, you should see the built-in
|
|
application 'djoy'. Just type 'djoy' at the NSH command prompt.
|
|
|
|
nxterm:
|
|
----------
|
|
This is yet another NSH configuration. This NSH configuration differs
|
|
from the other, however, in that it uses the NxTerm driver to host
|
|
the NSH shell.
|
|
|
|
NOTES:
|
|
|
|
1. This configuration uses the mconf-based configuration tool. To
|
|
change this configurations using that tool, you should:
|
|
|
|
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
|
see additional README.txt files in the NuttX tools repository.
|
|
|
|
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
|
reconfiguration process.
|
|
|
|
2. Some of the differences in this configuration include these settings
|
|
in the defconfig file:
|
|
|
|
These select NX Multi-User mode:
|
|
|
|
CONFG_NX_MULTIUSER=y
|
|
CONFIG_DISABLE_MQUEUE=n
|
|
|
|
The following definition in the defconfig file to enables the NxTerm
|
|
driver:
|
|
|
|
CONFIG_NXTERM=y
|
|
|
|
And this selects apps/examples/nxterm instead of apps/examples/nsh:
|
|
|
|
CONFIG_EXAMPLES_NXTERM=y
|
|
|
|
Other configuration settings of interest:
|
|
|
|
CONFIG_HOST_WINDOWS=y : Windows
|
|
CONFIG_WINDOWS_CYGWIN=y : with Cygwin
|
|
CONFIG_ARMV7M_TOOLCHAIN_BUILDROOT=y : NuttX buildroot under Linux or Cygwin
|
|
CONFIG_LCD_LANDSCAPE=y : 320x240 landscape
|
|
|
|
pm:

|
|
This is a configuration that is used to test STM32 power management, i.e.,
|
|
to test that the board can go into lower and lower states of power usage
|
|
as a result of inactivity. This configuration is based on the nsh2
|
|
configuration with modifications for testing power management. This
|
|
configuration should provide some guideline for power management in your
|
|
STM32 application.
|
|
|
|
NOTES:
|
|
|
|
1. This configuration uses the mconf-based configuration tool. To
|
|
change this configurations using that tool, you should:
|
|
|
|
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
|
see additional README.txt files in the NuttX tools repository.
|
|
|
|
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
|
reconfiguration process.
|
|
|
|
2. Default configuration is Cygwin under windows using the CodeSourcery
|
|
toolchain:
|
|
|
|
CONFIG_HOST_WINDOWS=y : Windows
|
|
CONFIG_WINDOWS_CYGWIN=y : Cygwin
|
|
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery under Windows
|
|
|
|
3. CONFIG_ARCH_CUSTOM_PMINIT and CONFIG_ARCH_IDLE_CUSTOM are necessary
|
|
parts of the PM configuration:
|
|
|
|
CONFIG_ARCH_CUSTOM_PMINIT=y
|
|
|
|
CONFIG_ARCH_CUSTOM_PMINIT moves the PM initialization from
|
|
arch/arm/src/stm32/stm32_pminitialiaze.c to boards/arm/stm32/stm3210-eval/src/stm32_pm.c.
|
|
This allows us to support board-specific PM initialization.
|
|
|
|
CONFIG_ARCH_IDLE_CUSTOM=y
|
|
|
|
The bulk of the PM activities occur in the IDLE loop. The IDLE loop
|
|
is special because it is what runs when there is no other task running.
|
|
Therefore when the IDLE executes, we can be assure that nothing else
|
|
is going on; this is the ideal condition for doing reduced power
|
|
management.
|
|
|
|
The configuration CONFIG_ARCH_IDLE_CUSTOM allows us to "steal" the
|
|
normal STM32 IDLE loop (of arch/arm/src/stm32/stm32_idle.c) and replace
|
|
this with our own custom IDLE loop (at boards/arm/stm32/stm3210-eval/src/up_idle.c).
|
|
|
|
4. Here are some additional things to note in the configuration:
|
|
|
|
CONFIG_PM_BUTTONS=y
|
|
|
|
CONFIG_PM_BUTTONS enables button support for PM testing. Buttons can
|
|
drive EXTI interrupts and EXTI interrupts can be used to wakeup for
|
|
certain reduced power modes (STOP mode). The use of the buttons here
|
|
is for PM testing purposes only; buttons would normally be part the
|
|
application code and CONFIG_PM_BUTTONS would not be defined.
|
|
|
|
CONFIG_RTC_ALARM=y
|
|
|
|
The RTC alarm is used to wake up from STOP mode and to transition to
|
|
STANDBY mode. This used of the RTC alarm could conflict with other
|
|
uses of the RTC alarm in your application.
|
|
|
|
usbserial:
|
|
---------
|
|
This configuration directory exercises the USB serial class
|
|
driver at examples/usbserial. See examples/README.txt for
|
|
more information.
|
|
|
|
CONFIG_ARMV7M_TOOLCHAIN_BUILDROOT=y : NuttX buildroot under Linux or Cygwin
|
|
|
|
USB debug output can be enabled as by changing the following
|
|
settings in the configuration file:
|
|
|
|
-CONFIG_DEBUG_FEATURES=n
|
|
-CONFIG_DEBUG_INFO=n
|
|
-CONFIG_DEBUG_USB=n
|

|
|
+CONFIG_EXAMPLES_USBSERIAL_TRACECONTROLLER=y
|
|
+CONFIG_EXAMPLES_USBSERIAL_TRACEINTERRUPTS=y
|
|
|
|
By default, the usbserial example uses the Prolific PL2303
|
|
serial/USB converter emulation. The example can be modified
|
|
to use the CDC/ACM serial class by making the following changes
|
|
to the configuration file:
|
|
|
|
-CONFIG_PL2303=y
|
|
+CONFIG_PL2303=n
|
|
|
|
-CONFIG_CDCACM=n
|
|
+CONFIG_CDCACM=y
|
|
|
|
The example can also be converted to use the alternative
|
|
USB serial example at apps/examples/usbterm by changing the
|
|
following:
|
|
|
|
-CONFIG_EXAMPLES_USBSERIAL=y
|
|
+CONFIG_EXAMPLES_USBSERIAL=n
|
|
|
|
usbmsc:
|
