Hardware
|
||||
========
|
||||
< Section needs updating >
|
||||
|
||||
GPIO - there are 144 I/O lines on the STM32L4xxZx with various pins pined out
|
||||
on the Nucleo 144.
|
||||
|
||||
Keep in mind that:
|
||||
1) The I/O is 3.3 Volt not 5 Volt like on the Arduino products.
|
||||
2) The Nucleo-144 board family has 3 pages of Solder Bridges AKA Solder
|
||||
Blobs (SB) that can alter the factory configuration. We will note SB
|
||||
in effect but will assume the facitory defualt settings.
|
||||
|
||||
Our main concern is establishing a console and LED utilization for
|
||||
debugging. Because so many pins can be multiplexed with so many functions,
|
||||
the above mentioned graphic may be helpful in indentifying a serial port.
|
||||
|
||||
There are 4 choices that can be made from the menuconfig:
|
||||
|
||||
CONFIG_NUCLEO_CONSOLE_ARDUINO or CONFIG_NUCLEO_CONSOLE_MORPHO or
|
||||
CONFIG_NUCLEO_CONSOLE_VIRTUAL or CONFIG_NUCLEO_CONSOLE_NONE
|
||||
|
||||
The CONFIG_NUCLEO_CONSOLE_NONE makes no preset for the console. You should still visit
|
||||
the U[S]ART selection and Device Drivers to disable any U[S]ART reamaing.
|
||||
|
||||
The CONFIG_NUCLEO_CONSOLE_ARDUINO configurations assume that you are using a
|
||||
standard Arduio RS-232 shield with the serial interface with RX on pin D0 and
|
||||
TX on pin D1 from USART6:
|
||||
|
||||

||||

||||

|
||||

|
||||
DO RX USART6_RX PG9
|
||||
D1 TX USART6_TX PG14
|
||||
-- ----- --------- -----
|
||||
|
||||
The CONFIG_NUCLEO_CONSOLE_MORPHO configurations uses Serial Port 8 (USART8)
|
||||
with TX on PE1 and RX on PE0.
|
||||
Serial
|
||||
------
|
||||
SERIAL_RX PE_0
|
||||
SERIAL_TX PE_1
|
||||
|
||||
The CONFIG_NUCLEO_CONSOLE_VIRTUAL configurations uses Serial Port 3 (USART3)
|
||||
with TX on PD8 and RX on PD9.
|
||||
Serial
|
||||
------
|
||||
SERIAL_RX PD9
|
||||
SERIAL_TX PD8
|
||||
|
||||
These signals are internally connected to the on board ST-Link
|
||||
|
||||
Of course if your design has used those pins you can choose a completely
|
||||
different U[S]ART to use as the console. In that Case, you will need to edit
|
||||
the include/board.h to select different U[S]ART and / or pin selections.
|
||||
|
||||
Buttons
|
||||
-------
|
||||
B1 USER: the user button is connected to the I/O PC13 (Tamper support, SB173
|
||||
ON and SB180 OFF)
|
||||
|
||||
LEDs
|
||||
----
|
||||
The Board provides a 3 user LEDs, LD1-LD3
|
||||
LED1 (Green) PB_0 (SB120 ON and SB119 OFF)
|
||||
LED2 (Blue) PB_7 (SB139 ON)
|
||||
LED3 (Red) PB_14 (SP118 ON)
|
||||
|
||||
- When the I/O is HIGH value, the LEDs are on.
|
||||
- When the I/O is LOW, the LEDs are off.
|
||||
|
||||
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_autoleds.c. The LEDs are used to encode OS
|
||||
related events as follows when the LEDs are available:
|
||||
|
||||
SYMBOL Meaning RED GREEN BLUE
|
||||
------------------- ----------------------- --- ----- ----
|
||||
|
||||
LED_STARTED NuttX has been started OFF OFF OFF
|
||||
LED_HEAPALLOCATE Heap has been allocated OFF OFF ON
|
||||
LED_IRQSENABLED Interrupts enabled OFF ON OFF
|
||||
LED_STACKCREATED Idle stack created OFF ON ON
|
||||
LED_INIRQ In an interrupt NC NC ON (momentary)
|
||||
LED_SIGNAL In a signal handler NC ON OFF (momentary)
|
||||
LED_ASSERTION An assertion failed ON NC ON (momentary)
|
||||
LED_PANIC The system has crashed ON OFF OFF (flashing 2Hz)
|
||||
LED_IDLE MCU is is sleep mode ON OFF OFF
|
||||
|
||||
|
||||
OFF - means that the OS is still initializing. Initialization is very fast
|
||||
so if you see this at all, it probably means that the system is
|
||||
hanging up somewhere in the initialization phases.
|
||||
|
||||
GREEN - This means that the OS completed initialization.
|
||||
|
||||
BLUE - Whenever and interrupt or signal handler is entered, the BLUE LED is
|
||||
illuminated and extinguished when the interrupt or signal handler
|
||||
exits.
|
||||
|
||||
VIOLET - If a recovered assertion occurs, the RED and blue LED will be
|
||||
illuminated briefly while the assertion is handled. You will
|
||||
probably never see this.
|
||||
|
||||
Flashing RED - In the event of a fatal crash, all other LEDs will be
|
||||
extinguished and RED LED will FLASH at a 2Hz rate.
|
||||
|
||||
|
||||
Thus if the GREEN LED is lit, NuttX has successfully booted and is,
|
||||
apparently, running normally. If the RED LED is flashing at
|
||||
approximately 2Hz, then a fatal error has been detected and the system has
|
||||
halted.

CONFIG_STM32L4_UART8=y
|
||||
CONFIG_UART8_SERIALDRIVER=y
|
||||
CONFIG_UART8_SERIAL_CONSOLE=y

CONFIG_UART8_2STOP=0
|

|
||||
Virtual COM Port (CONFIG_NUCLEO_CONSOLE_VIRTUAL)
|
||||
----------------
|
||||
Yet another option is to use USART3 and the USB virtual COM port. This
|
||||
option may be more convenient for long term development, but is painful
|
||||
to use during board bring-up.
|
||||
|
||||
Solder Bridges. This configuration requires:
|
||||
|
||||
PD8 USART3 TX SB5 ON and SB7 OFF (Default)
|
||||
PD9 USART3 RX SB6 ON and SB4 OFF (Default)
|
||||
|
||||
Configuring USART3 is the same as given above but add the S and #3.
|
||||
|
||||
Question: What BAUD should be configure to interface with the Virtual
|
||||
COM port? 115200 8N1?
|
||||
|
||||
Default
|
||||
-------
|
||||
As shipped, SB4 and SB7 are open and SB5 and SB6 closed, so the
|
||||
virtual COM port is enabled.
|
||||
|
||||
|
||||
SPI
|
||||
---
|
||||
Since this board is so generic, having a quick way to vet the SPI
|
||||
configuration seams in order. So the board provides a quick test
|
||||
that can be selected vi CONFIG_NUCLEO_SPI_TEST that will initalise
|
||||
the selected buses (SPI1-SPI3) and send some text on the bus at
|
||||
application initalization time board_app_initialize.
|
||||
|
||||
SDIO
|
||||
----
|
||||
To test the SD performace one can use a SparkFun microSD Sniffer
|
||||
from https://www.sparkfun.com/products/9419 or similar board
|
||||
and connect it as follows:
|
||||
|
||||
VCC V3.3 CN11 16
|
||||
GND GND CN11-8
|
||||
CMD PD2 CN11-4
|
||||
CLK PC12 CN11-3
|
||||
DAT0 - PC8 CN12-2
|
||||
DAT1 - PC9 CN12-1
|
||||
DAT2 PC10 CN11-1
|
||||
CD PC11 CN11-2
|
||||
|
||||
Configurations
|
||||
==============
|
||||
|
||||
nsh:
|
||||
----
|
||||
Configures the NuttShell (nsh) located at apps/examples/nsh for the
|
||||
Nucleo-144 boards. The Configuration enables the serial interfaces
|
||||
on USART6. Support for builtin applications is enabled, but in the base
|
||||
configuration no builtin applications are selected (see NOTES below).
|
||||
|
||||
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
|
||||
see additional README.txt files in the NuttX tools repository.
|
||||
|
||||
b. If this is the intall configuration then Execute
|
||||
'cd tools && ./configure.sh nucleo-144/nsh && cd ..'
|
||||
in nuttx/ in order to start configuration process.
|
||||
Caution: Doing this step more than once will overwrite .config with
|
||||
the contents of the nucleo-144/nsh/defconfig file.
|
||||
|
||||
c. Execute 'make oldconfig' in nuttx/ in order to refresh the
|
||||
configuration.
|
||||
|
||||
d. Execute 'make menuconfig' in nuttx/ in order to start the
|
||||
reconfiguration process.
|
||||
|
||||
e. Save the .config file to reuse it in the future starting at step d.
|
||||
|
||||
2. By default, this configuration uses the ARM GNU toolchain
|
||||
for Linux. That can easily be reconfigured, of course.
|
||||
|
||||
CONFIG_HOST_LINUX=y : Builds under Linux
|
||||
CONFIG_ARMV7M_TOOLCHAIN_GNU_EABIL=y : ARM GNU for Linux
|
||||
|
||||
3. Although the default console is USART3 (which would correspond to
|
||||
the Virtual COM port) I have done all testing with the console
|
||||
device configured for UART8 (see instruction above under "Serial
|
||||
Consoles).

/* The STM32F746NGH6 has 1024Kb of main FLASH memory. This FLASH memory can
|
||||
* be accessed from either the AXIM interface at address 0x0800:0000 or from
|
||||
* the ITCM interface at address 0x0020:0000.
|
||||
*
|
||||
* Additional information, including the option bytes, is available at at
|
||||
* FLASH at address 0x1ff0:0000 (AXIM) or 0x0010:0000 (ITCM).
|
||||
*
|
||||
* In the STM32F746NGH6, two different boot spaces can be selected through
|
||||
* the BOOT pin and the boot base address programmed in the BOOT_ADD0 and
|
||||
* BOOT_ADD1 option bytes:
|
||||
*
|
||||
* 1) BOOT=0: Boot address defined by user option byte BOOT_ADD0[15:0].
|
||||
* ST programmed value: Flash on ITCM at 0x0020:0000
|
||||
* 2) BOOT=1: Boot address defined by user option byte BOOT_ADD1[15:0].
|
||||
* ST programmed value: System bootloader at 0x0010:0000
|
||||
*
|
||||
* NuttX does not modify these option byes. On the unmodified STM32F746G
|
||||
* DISCO board, the BOOT0 pin is at ground so by default, the STM32 will boot
|
||||
* to address 0x0020:0000 in ITCM FLASH.
|
||||
*
|
||||
* The STM32F746NGH6 also has 320Kb of data SRAM (in addition to ITCM SRAM).
|
||||
* SRAM is split up into three blocks:
|
||||
*
|
||||
* 1) 64Kb of DTCM SRM beginning at address 0x2000:0000
|
||||
* 2) 240Kb of SRAM1 beginning at address 0x2001:0000
|
||||
* 3) 16Kb of SRAM2 beginning at address 0x2004:c000
|
||||
*
|
||||
* When booting from FLASH, FLASH memory is aliased to address 0x0000:0000
|
||||
* where the code expects to begin execution by jumping to the entry point in
|
||||
* the 0x0800:0000 address range.
|
||||
*
|
||||
* For MPU support, the kernel-mode NuttX section is assumed to be 128Kb of
|
||||
* FLASH and 4Kb of SRAM. That is an excessive amount for the kernel which
|
||||
* should fit into 64KB and, of course, can be optimized as needed (See
|
||||
* also configs/stm32f746g-disco/scripts/kernel-space.ld). Allowing the
|
||||
* additional does permit addition debug instrumentation to be added to the
|
||||
* kernel space without overflowing the partition.
|
||||
*
|
||||
* Alignment of the user space FLASH partition is also a critical factor:
|
||||
* The user space FLASH partition will be spanned with a single region of
|
||||
* size 2**n bytes. The alignment of the user-space region must be the same.
|
||||
* As a consequence, as the user-space increases in size, the alignment
|
||||
* requirement also increases.
|
||||
*
|
||||
* This alignment requirement means that the largest user space FLASH region
|
||||
* you can have will be 512KB at it would have to be positioned at
|
||||
* 0x08800000. If you change this address, don't forget to change the
|
||||
* CONFIG_NUTTX_USERSPACE configuration setting to match and to modify
|
||||
* the check in kernel/userspace.c.
|
||||
*
|
||||
* For the same reasons, the maximum size of the SRAM mapping is limited to
|
||||
* 4KB. Both of these alignment limitations could be reduced by using
|
||||
* multiple regions to map the FLASH/SDRAM range or perhaps with some
|
||||
* clever use of subregions.
|
||||
*
|
||||
* A detailed memory map for the 112KB SRAM region is as follows:
|
||||
*
|
||||
* 0x20001 0000: Kernel .data region. Typical size: 0.1KB
|
||||
* ------- ---- Kernel .bss region. Typical size: 1.8KB
|
||||
* 0x20001 0800: Kernel IDLE thread stack (approximate). Size is
|
||||
* determined by CONFIG_IDLETHREAD_STACKSIZE and
|
||||
* adjustments for alignment. Typical is 1KB.
|
||||
* ------- ---- Padded to 4KB
|
||||
* 0x20001 1000: User .data region. Size is variable.
|
||||
* ------- ---- User .bss region Size is variable.
|
||||
* 0x20001 2000: Beginning of kernel heap. Size determined by
|
||||
* CONFIG_MM_KERNEL_HEAPSIZE.
|
||||
* ------- ---- Beginning of user heap. Can vary with other settings.
|
||||
* 0x20004 c000: End+1 of SRAM1

* Description:

* Perform application specific initialization. This function is never

* (non-standard) boardctl() interface using the command BOARDIOC_INIT.

*

* Input Parameters:
|
||||
* arg - The boardctl() argument is passed to the board_app_initialize()
|
||||
* implementation without modification. The argument has no
|
||||
* meaning to NuttX; the meaning of the argument is a contract
|
||||
* between the board-specific initalization logic and the the
|
||||
* matching application logic. The value cold be such things as a
|
||||
* mode enumeration value, a set of DIP switch switch settings, a
|
||||
* pointer to configuration data read from a file or serial FLASH,
|
||||
* or whatever you would like to do with it. Every implementation
|
||||
* should accept zero/NULL as a default configuration.
|
||||
*
|
||||
* Returned Value:
|
||||
* Zero (OK) is returned on success; a negated errno value is returned on
|
||||
* any failure to indicate the nature of the failure.

* Description:
|
||||
* The external functions, stm32_spi1/2/3select and stm32_spi1/2/3status must be
|
||||
* provided by board-specific logic. They are implementations of the select
|
||||
* and status methods of the SPI interface defined by struct spi_ops_s (see
|
||||
* include/nuttx/spi/spi.h). All other methods (including stm32_spibus_initialize())
|
||||
* are provided by common STM32 logic. To use this common SPI logic on your
|
||||
* board:
|
||||
*
|
||||
* 1. Provide logic in stm32_boardinitialize() to configure SPI chip select
|
||||
* pins.
|
||||
* 2. Provide stm32_spi1/2/3select() and stm32_spi1/2/3status() functions in your
|
||||
* board-specific logic. These functions will perform chip selection and
|
||||
* status operations using GPIOs in the way your board is configured.
|
||||
* 3. Add a calls to stm32_spibus_initialize() in your low level application
|
||||
* initialization logic
|
||||
* 4. The handle returned by stm32_spibus_initialize() may then be used to bind the
|
||||
* SPI driver to higher level logic (e.g., calling
|
||||
* mmcsd_spislotinitialize(), for example, will bind the SPI driver to
|
||||
* the SPI MMC/SD driver).
