-Nucleo-64 Boards:
-=================
-
-The Nucleo-64 is a standard board for use with several STM32 parts in the
-LQFP64 package.  Variants include
-
-  Order code    Targeted STM32
-  ------------- --------------
-  NUCLEO-F030R8 STM32F030R8T6
-  NUCLEO-F070RB STM32F070RBT6
-  NUCLEO-F072RB STM32F072RBT6
-  NUCLEO-F091RC STM32F091RCT6
-  NUCLEO-F103RB STM32F103RBT6
-  NUCLEO-F302R8 STM32F302R8T6

-
-This directory is intended to support all Nucleo-64 variants since the
-boards are identical, differing only in the installed part.  This common
-board design provides uniformity in the documentation from ST and should
-allow us to quickly change configurations by just cloning a configuration
-and changing the CPU choice and board initialization.  Unfortunately for
-the developer, the CPU specific information must be extracted from the
-common information in the documentation.
-
-Please read the User Manaul UM1727: Getting started with STM32 Nucleo board
-software development tools and take note of the Powering options for the
-board (6.3 Power supply and power selection) and the Solder bridges based
-hardware configuration changes that are configurable (6.11 Solder bridges).
-
-Common Board Features:
----------------------
-
-The STM32 Nucleo board offers the following features:
-
-  - STM32 microcontroller in LQFP64 package
-  - Two types of extension resources
-    Arduino™ Uno V3 connectivity
-    ST morpho extension pin headers for full access to all STM32 I/Os
-  - ARM® mbed™ (see http://mbed.org)
-  - On-board ST-LINK/V2-1 debugger and programmer with SWD connector
-    Selection-mode switch to use the kit as a standalone ST-LINK/V2-1
-  - Flexible board power supply:
-    USB VBUS or external source (3.3V, 5V, 7 - 12V)
-    Power management access point
-  - Three LEDs:
-    USB communication (LD1), user LED (LD2), power LED (LD3)
-  - Two push-buttons: USER and RESET
-  - USB re-enumeration capability. Three different interfaces supported on USB:
-    Virtual COM port
-    Mass storage
-    Debug port
-  - Comprehensive free software HAL library including a variety of software examples
-
-  Peripherals:    8 leds, 2 push button (3 LEDs, 1 button) under software
-                  control
-  Debug:          STLINK/V2-1 debugger/programmer Uses a STM32F103CB to
-                  provide a ST-Link for programming, debug similar to the
-                  OpenOcd FTDI function - USB to JTAG front-end.

-
-Development Environment
-=======================
-
-  Either Linux or Cygwin on Windows can be used for the development environment.
-  The source has been built only using the GNU toolchain (see below).  Other
-  toolchains will likely cause problems.
-
-  All testing has been conducted using the GNU toolchain from ARM for Linux.
-  found here https://launchpad.net/gcc-arm-embedded/4.9/4.9-2015-q3-update/+download/gcc-arm-none-eabi-4_9-2015q3-20150921-linux.tar.bz2
-
-  If you change the default toolchain, then you may also have to modify the PATH in
-  the setenv.h file if your make cannot find the tools.
-
-Basic configuration & build steps
-==================================
-
-  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
-  be modified to point to the correct path to the Cortex-M4 GCC toolchain (if
-  different from the default in your PATH variable).
-
-   - Configures nuttx creating .config file in the nuttx directory.
-     cd tools && ./configure.sh nucleo-f746zg/nsh && cd ..
-   - Refreshes the .config file with the latest available configurations.
-     make oldconfig
-   - Select the features you want in the build.
-     make menuconfig
-   - Builds Nuttx with the features you selected.
-     make
