Nucleo-64 Boards:
=================
The Nucleo-64 is a standard board for use with several STM32 parts in the
LQFP64 package. Variants include

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.
Expansion I/F: ST Zio and Extended Ardino and Morpho Headers

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
