HY-MiniSTM32V
|
|
=============
|
|
|
|
This page discusses issues unique to NuttX configurations for the
|
|
HY-MiniSTM32V development board.
|
|
|
|
ST Bootloader
|
|
=============
|
|
|
|
A bootloader code is available in an internal boot ROM memory (called
|
|
'system memory' in STM documentation) in all STM32 MCUs. For the F103xx
|
|
this bootloader can be used to upload & flash a firmware image through
|
|
the USART1.
|
|
|
|
Notes:
|
|
|
|
- The bootloader is activated by the BOOT0 / BOOT1 pins after a MCU reset.
|
|
See STM application note 2606 for more details.
|
|
- On the hymini-stm32 board the USART1 is connected to a PL2303
|
|
USB<->serial converter.
|
|
|
|
To enter bootloader mode in the hymini-stm32 board:
|
|
|
|
- Press the 'boot0' button (located next to 'reset' button)
|
|
- While boot0 button is pressed, reset the board through the reset button.
|
|
- Once you pressed / released the 'reset' button, the MCU has (re)started
|
|
in bootloader mode (and you can then release the boot0 button).
|
|
|
|
A flash utility must be used on your development workstation to upload / flash
|
|
a firmware image. (The 'stm32flash' open source tool, available at
|
|
http://stm32flash.googlecode.com/ has been used successfully).
|
|
|
|
LEDs
|
|
====
|
|
|
|
The HY-MiniSTM32 board provides only two controllable LEDs labeled LED1 and LED2.
|
|
Usage of these LEDs is defined in include/board.h and src/up_leds.c.
|
|
They are encoded as follows::
|
|
|
|
=================== ======================= ======= =======
|
|
SYMBOL Meaning LED1* LED2
|
|
=================== ======================= ======= =======
|
|
LED_STARTED NuttX has been started OFF OFF
|
|
LED_HEAPALLOCATE Heap has been allocated ON OFF
|
|
LED_IRQSENABLED Interrupts enabled OFF ON
|
|
LED_STACKCREATED Idle stack created ON OFF
|
|
LED_INIRQ In an interrupt** OFF N/C
|
|
LED_SIGNAL In a signal handler*** N/C ON
|
|
LED_ASSERTION An assertion failed ON ON
|
|
LED_PANIC The system has crashed BLINK BLINK
|
|
LED_IDLE STM32 is is sleep mode (Optional, not used)
|
|
=================== ======================= ======= =======
|
|
|
|
* If NuttX starts correctly, normal state is to have LED1 on and LED2 off.
|
|
** LED1 is turned off during interrupt.
|
|
*** LED2 is turned on during signal handler.
|
|
|
|
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.

Configurations
|
|
==============
|
|
|
|
NOTES:
|
|
|
|
- All configurations described below are using the mconf-based
|
|
configuration tool. To change their configuration 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.
|
|
|
|
- All configurations use a generic GNU EABI toolchain for Linux by
|
|
default.
|
|
|
|
- They are all configured to generate a binary image that can be flashed
|
|
through the STM32 internal bootloader.
|
|
|
|
Each HY-MiniSTM32V configuration is maintained in a sub-directory and
|
|
can be selected as follow::
|
|
|
|
tools/configure.sh hymini-stm32v:<subdir>
|
|
|
|
Where <subdir> is one of the following:
|
|
|
|
nsh and nsh2
|
|
------------
|
|
|
|
Configure the NuttShell (nsh) located at examples/nsh.
|

|
(1) You will probably need to the PATH environment variable to set
|
|
up the correct PATH variable for whichever toolchain you may use.
|
|
(2) 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.
|
|
(3) 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 NOTICE file. Please do not use FAT
|
|
long file name unless you are familiar with these patent issues.
|
|
(4) 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.
|
|
(5) Option CONFIG_NSH_ARCHINIT must be enabled in order to call the SDIO slot
|
|
initialization code.
|
|
|
|
usbmsc
|
|
------
|
|
|
|
This configuration directory exercises the USB mass storage
|
|
class driver at system/usbmsc. See examples/README.txt for
|
|
more information.
|
|
|
|
usbnsh
|
|
------
|
|
|
|
This is another NSH example. If differs from other 'nsh' configurations
|
|
in that this configurations uses a USB serial device for console I/O.
|
|
|
|
NOTES:
|
|
|
|
1. This configuration does have UART2 output enabled and set up as
|
|
the system logging device::
|
|
|
|
CONFIG_SYSLOG_CHAR=y : Use a character device for system logging
|
|
CONFIG_SYSLOG_DEVPATH="/dev/ttyS0" : UART2 will be /dev/ttyS0
|
|
|
|
However, there is nothing to generate SYSLOG output in the default
|
|
configuration so nothing should appear on UART2 unless you enable
|
|
some debug output or enable the USB monitor.
|
|
|
|
2. Enabling USB monitor SYSLOG output. If tracing is enabled, the USB
|
|
device will save encoded trace output in in-memory buffer; if the
|
|
USB monitor is enabled, that trace buffer will be periodically
|
|
emptied and dumped to the system logging device (UART2 in this
|
|
configuration)::
|
|
|
|
CONFIG_USBDEV_TRACE=y : Enable USB trace feature
|
|
CONFIG_USBDEV_TRACE_NRECORDS=128 : Buffer 128 records in memory
|
|
CONFIG_NSH_USBDEV_TRACE=n : No builtin tracing from NSH
|
|
CONFIG_NSH_ARCHINIT=y : Automatically start the USB monitor
|
|
CONFIG_USBMONITOR=y : Enable the USB monitor daemon
|
|
CONFIG_USBMONITOR_STACKSIZE=2048 : USB monitor daemon stack size
|
|
CONFIG_USBMONITOR_PRIORITY=50 : USB monitor daemon priority
|
|
CONFIG_USBMONITOR_INTERVAL=2 : Dump trace data every 2 seconds
|
|
|
|
CONFIG_USBMONITOR_TRACEINIT=y : Enable TRACE output
|
|
CONFIG_USBMONITOR_TRACECLASS=y
|
|
CONFIG_USBMONITOR_TRACETRANSFERS=y
|
|
CONFIG_USBMONITOR_TRACECONTROLLER=y
|
|
CONFIG_USBMONITOR_TRACEINTERRUPTS=y
|
|
|
|
Using the Prolifics PL2303 Emulation
|
|
------------------------------------
|
|
You could also use the non-standard PL2303 serial device instead of
|
|
the standard CDC/ACM serial device by changing::
|
|
|
|
CONFIG_CDCACM=y : Disable the CDC/ACM serial device class
|
|
CONFIG_CDCACM_CONSOLE=y : The CDC/ACM serial device is NOT the console
|
|
CONFIG_PL2303=y : The Prolifics PL2303 emulation is enabled
|
|
CONFIG_PL2303_CONSOLE=y : The PL2303 serial device is the console
