ST Nucle H743ZI
|
|
===============
|
|
|
|
This page discusses issues unique to NuttX configurations for the
|
|
STMicro NUCLEO-H743ZI development board featuring the STM32H743ZI
|
|
MCU. The STM32H743ZI is a 400MHz Cortex-M7 operation with 2MBytes Flash
|
|
memory and 1MByte SRAM. The board features:
|
|
|
|
- On-board ST-LINK/V2-1 for programming and debugging,
|
|
- Mbed-enabled (mbed.org)
|
|
- 3 user LEDs
|
|
- Two pushbuttons (user and reset)
|
|
- 32.768 kHz crystal oscillator
|
|
- USB OTG FS with Micro-AB connectors
|
|
- Ethernet connector compliant with IEEE-802.3-2002
|
|
- Board connectors:
|
|
- USB with Micro-AB
|
|
- SWD
|
|
- Ethernet RJ45
|
|
- ST Zio connector including Arduino Uno V3
|
|
- ST morpho

Serial Console
|
|
==============
|
|
|
|
Many options are available for a serial console via the Morpho connector.
|
|
Here two common serial console options are suggested:
|
|
|
|
1. Arduino Serial Shield.
|
|
|
|
If you are using a standard Arduino RS-232 shield with the serial
|
|
interface with RX on pin D0 and TX on pin D1 from USART6:
|
|
|
|
======== ========= =====
|
|
ARDUINO FUNCTION GPIO
|
|
======== ========= =====
|
|
DO RX USART6_RX PG9
|
|
D1 TX USART6_TX PG14
|
|
======== ========= =====
|
|
|
|
2. Nucleo Virtual Console.
|
|
|
|
The virtual console uses Serial Port 3 (USART3) with TX on PD8 and RX on
|
|
PD9.
|
|
|
|
================= ===
|
|
VCOM Signal Pin
|
|
================= ===
|
|
SERIAL_RX PD9
|
|
SERIAL_TX PD8
|
|
================= ===
|
|
|
|
These signals are internally connected to the on board ST-Link.
|
|
|
|
The Nucleo virtual console is the default serial console in all
|
|
configurations unless otherwise stated in the description of the
|
|
configuration.

|
Configurations
|
|
==============
|
|
|
|
Information Common to All Configurations
|
|
----------------------------------------
|
|
|
|
Each Nucleo-H743ZI configuration is maintained in a sub-directory and
|
|
can be selected as follow::
|
|
|
|
tools/configure.sh [options] viewtool-stm32f107:<subdir>
|
|
|
|
Where options should specify the host build platform (-l for Linux, -c for
|
|
Cygwin under Windows, etc.). Try 'tools/configure.sh -h' for the complete
|
|
list of options.
|
|
|
|
Before starting the build, make sure that (1) your PATH environment variable
|
|
includes the correct path to your toolchain, and (2) you have the correct
|
|
toolchain selected in the configuration.
|
|
|
|
And then build NuttX by simply typing the following. At the conclusion of
|
|
the make, the nuttx binary will reside in an ELF file called, simply, nuttx.::
|
|
|
|
make
|
|
|
|
The <subdir> that is provided above as an argument to the tools/configure.sh
|
|
must be is one of the following.
|
|
|
|
NOTES:
|
|
|
|
1. These configurations use the mconf-based configuration tool. To
|
|
change any of these configurations 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.
|
|
|
|
2. Unless stated otherwise, all configurations generate console
|
|
output on the ST-Link VCOM, USART3.
|
|
|
|
3. Unless otherwise stated, the configurations are setup for Linux by
|
|
default:
|
|
|
|
Build Setup::
|
|
|
|
CONFIG_HOST_LINUX=y : Linux host operating system
|
|
|
|
4. All of these configurations use the general arm-none-eabi toolchain for
|
|
Linux That toolchain selection can easily be reconfigured using 'make
|
|
menuconfig'.
|
|
|
|
5. These configurations all assume that you are loading code using
|
|
something like the ST-Link v2 JTAG. None of these configurations are
|
|
setup to use the DFU bootloader but should be easily reconfigured to
|
|
use that bootloader if so desired.
|
|
|
|
Configuration Sub-directories
|
|
=============================
|
|
|
|
nsh:
|
|
----
|
|
|
|
This configuration provides a basic NuttShell configuration (NSH)
|
|
for the Nucleo-H743ZI. The default console is the VCOM on USART3.
|
|
|
|
mcuboot:
|
|
--------
|
|
|
|
This configuration provides a base implementation for mcuboot integration
|
|
in nuttx.
|
|
|
|
mcuboot-loader: Nuttx app-based bootloader.
|
|
mcuboot-app: Nuttx app with nsh as entrypoint.
