cuiziwei 25eb09c3bb nuttx/boards:add KEEP to (.init_array .init_array.) replace (.init_array .init_array.) with KEEP((.init_array .init_array.)). The KEEP statement within a linker script will instruct the linker to keep the specified section, even if no symbols inside it are referenced. This statement is used within the SECTIONS section of the linker script. This becomes relevant when garbage collection is performed at link time, enabled by passing the --gc-sections switch to the linker. The KEEP statement instructs the linker to use the specified section as a root node when creating a dependency graph, looking for unused sections. Essentially forcing the section to be marked as used. Signed-off-by: cuiziwei <cuiziwei@xiaomi.com>		2023-08-05 05:02:25 -07:00

NUCLEO-WB55RG README
======================

  This README file discusses the port of NuttX to the STMicroelectronics
  NUCLEO-WB55RG board.  That board features the multi-protocol wireless and
  ultra-low-power STM32WB55RGV6 MCU with 1MiB of Flash and 256KiB of SRAM.
  A dedicated M0+ coprocessor is responsible for performing the real-time
  low layer operations via one of the available wireless stacks distributed
  as binaries in STM32CubeWB package.

Status
======

  April 2022: The nucleo-wb55rg board minimal setup compiles successfully.

  June 2022: All STM32WB chip family is defined, many of peripherals are
    supported - GPIO, EXTI, DMA, timers, flash, PWR, RTC, USART/LPUART, SPI,
    IPCC. SRAM2 heap allocation works. Builtin apps work and ostest passed.

  July 2022: Added BLE support with mailbox IPC driver.

LEDs
====

  The board has 3 user leds:
    LED1 (Blue)      PB5
    LED2 (Green)     PB0
    LED3 (Red)       PB1

  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.

Buttons
=======

  The board has 3 user buttons:
    SW1     PC4 (needs SB47 close)
    SW2     PD0
    SW3     PD1

Serial Consoles
===============

  The MCU's USART1 is connected to the on-board ST-LINK/V2-1 and exposed as
  a Virtual COM Port over the same Micro-USB Type B connection used for
  programming/debugging.

Configurations
==============

  nsh:

    Configures the NuttShell (nsh) located at examples/nsh.  This
    configuration is focused on low level, command-line driver testing.

  ble:

    Besides the NuttShell this configuration also enables BLE support.
    It includes btsak application for testing BLE applications.

  nimble:

    Besides the NuttShell it includes nimble example application which
    uses NimBLE host stack.
