STM32WB family

st.com STM32WB family page

This ST MCU family is dual-core : based on an Arm Cortex-M4 core and an Arm Cortex-M0+ core.

  • M4 core is dedicated to application (mbed-os)
  • M0 core is dedicated to BLE FW (only binary, source files not provided)

Supported boards

NUCLEO_WB55RG

st.com STM32WB55RG MCU page

st.com NUCLEO page

mbed.com NUCLEO page

  • Total FLASH is 1MB, but note that it is shared by M4 and M0 cores.

    • mbed-os application size is then limited to 768 KB

  • RAM: 256 KB

    • SRAM1: 192 KB
    • SRAM2a: 32 KB
    • SRAM2b: 32 KB

SRAM1 is dedicated for M4 core, and then for mbed-os applications.

SRAM2 is dedicated for M0 core and inter CPU communication, and then can not be addressed.

BLE

MBED-OS support

BLE feature is based on Cordio stack and API (above HCI) implementation.

Note that the BLE controller firmware running on the cortex-M0 is the same as in STcubeFW solution

  • within mbed, the controller will run only the below-HCI part
  • within STcubeFW (and STM32WPAN middleware), it can run also up to GATT / GAP layers ...

BLE FW flashing procedure

Release Note and complete flashing procedure: https://htmlpreview.github.io/?https://github.com/STMicroelectronics/STM32CubeWB/blob/master/Projects/STM32WB_Copro_Wireless_Binaries/STM32WB5x/Release_Notes.html

  • STEP 1: Use STM32CubeProgrammer

https://www.st.com/en/development-tools/stm32cubeprog.html

FLASHPATH="C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin"
export PATH=$FLASHPATH:$PATH

  • STEP 2: Access to Bootloader USB Interface (system flash)

    • Boot0 pin set to VDD : Jumper between CN7.5(VDD) and CN7.7(Boot0)
    • Jumper JP1 on USB_MCU
    • Power ON via USB_USER
