B-L475E-IOT01A IoT Node (``b-l475e-iot01a``)
|
|
============================================
|
|
|
|
The B-L475E-IOT01A IoT Node uses the STM32L475VG SoC which is based on
|
|
ARM Cortex-M4F core. It is part of STMicroelectronics
|
|
:doc:`STM32 boards </system/arm/stm32>` and more specifically the STM32L4
|
|
ultra-low power series. The STM32L4x5 chip runs at up to 80 MHz and
|
|
integrates 128 KiB of SRAM and up to 1MiB of Flash. The B-L475E-IOT01A board
|
|
namely features 64 Mibit QSPI Flash, BT, WiFi and RF connectivity,
|
|
USART, I2C, SPI, CAN and USB OTG, as well as a variety of sensors.

|
|
|
|
Missing devices
|
|
"""""""""""""""
|
|
|
|
The B-L475E-IOT01A does *not* support the following devices:
|
|
|
|
- Extended interrupts and events controller (EXTI)
|
|
- Reset and clock control (RCC)
|
|
- Serial ports (UART)
|
|
- System configuration controller (SYSCFG)
|
|
- General-purpose I/Os (GPIO)
|
|
- Analog to Digital Converter (ADC)
|
|
- SPI controller
|
|
- Timer controller (TIMER)
|
|

Boot options
|
|
""""""""""""
|
|
|
|
The B-L475E-IOT01A machine can be started using the ``-kernel``
|
|
option to load a firmware. Example:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ qemu-system-arm -M b-l475e-iot01a -kernel firmware.bin
