Nucleo-64 Boards
|
||
|
|
================
|
||
|
|
|
||
|
|
The Nucleo-F410RB board is member of the Nucleo-64 board family. The
|
||
|
|
Nucleo-64 is a standard board for use with several STM32 parts in the
|
||
|
|
LQFP64 package. Variants include

Hardware
|
||
|
|
========
|
||
|
|
|
||
|
|
Buttons
|
||
|
|
-------
|
||
|
|
B1 USER: the user button is connected to the I/O PC13 (pin 2) of the STM32
|
||
|
|
microcontroller.
|
||
|
|
|
||
|
|
LEDs
|
||
|
|
----
|
||
|
|
The Nucleo F410RB provide a single user LED, LD2. LD2
|
||
|
|
is the green LED connected to Arduino signal D13 corresponding to MCU I/O
|
||
|
|
PA5 (pin 21) or PB13 (pin 34) depending on the STM32target.
|
||
|
|
|
||
|
|
- When the I/O is HIGH value, the LED is on.
|
||
|
|
- When the I/O is LOW, the LED is 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/sam_leds.c. The LEDs are used to encode OS-related
|
||
|
|
events as follows when the red LED (PE24) is available:
|
||
|
|
|
||
|
|
SYMBOL Meaning LD2
|
||
|
|
------------------- ----------------------- -----------
|
||
|
|
LED_STARTED NuttX has been started OFF
|
||
|
|
LED_HEAPALLOCATE Heap has been allocated OFF
|
||
|
|
LED_IRQSENABLED Interrupts enabled OFF
|
||
|
|
LED_STACKCREATED Idle stack created ON
|
||
|
|
LED_INIRQ In an interrupt No change
|
||
|
|
LED_SIGNAL In a signal handler No change
|
||
|
|
LED_ASSERTION An assertion failed No change
|
||
|
|
LED_PANIC The system has crashed Blinking
|
||
|
|
LED_IDLE MCU is is sleep mode Not used
|
||
|
|
|
||
|
|
Thus if LD2, NuttX has successfully booted and is, apparently, running
|
||
|
|
normally. If LD2 is flashing at approximately 2Hz, then a fatal error
|
||
|
|
has been detected and the system has halted.

Solder Bridges. This configuration requires:
|
||
|
|
|
||
|
|
- SB62 and SB63 Closed: PA2 and PA3 on STM32 MCU are connected to D1 and D0
|
||
|
|
(pin 7 and pin 8) on Arduino connector CN9 and ST Morpho connector CN10
|
||
|
|
as USART signals. Thus SB13 and SB14 should be OFF.
|
||
|
|
|
||
|
|
- SB13 and SB14 Open: PA2 and PA3 on STM32F103C8T6 (ST-LINK MCU) are
|
||
|
|
disconnected to PA3 and PA2 on STM32 MCU.
|
||
|

Virtual COM Port
|
||
|
|
----------------
|
||
|
|
Yet another option is to use UART2 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:
|
||
|
|
|
||
|
|
- SB62 and SB63 Open: PA2 and PA3 on STM32 MCU are disconnected to D1
|
||
|
|
and D0 (pin 7 and pin 8) on Arduino connector CN9 and ST Morpho
|
||
|
|
connector CN10.
|
||
|
|
|
||
|
|
- SB13 and SB14 Closed: PA2 and PA3 on STM32F103C8T6 (ST-LINK MCU) are
|
||
|
|
connected to PA3 and PA2 on STM32 MCU to have USART communication
|
||
|
|
between them. Thus SB61, SB62 and SB63 should be OFF.
|
||
|
|
|
||
|
|
Configuring USART2 is the same as given above.
|
||
|
|
|
||
|
|
Question: What BAUD should be configure to interface with the Virtual
|
||
|
|
COM port? 115200 8N1?
|
||
|
|
|
||
|
|
Default
|
||
|
|
-------
|
||
|
|
As shipped, SB62 and SB63 are open and SB13 and SB14 closed, so the
|
||
|
|
virtual COM port is enabled.
|
||
|
|
|
||
|
|
Configurations
|
||
|
|
==============
|
||
|
|
|
||
|
|
nsh:
|
||
|
|
---------
|
||
|
|
Configures the NuttShell (nsh) located at apps/examples/nsh for the
|
||
|
|
Nucleo-F410RB board. The Configuration enables the serial interfaces
|
||
|
|
on UART2. 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. Execute 'make menuconfig' in nuttx/ in order to start the
|
||
|
|
reconfiguration process.
