Detailed Description
Support for the STM32 p-nucleo-wb55.
Overview
The p-nucleo-wb55 is a multi-protocol wireless and ultra-low-power device embedding a powerful and ultra-low-power radio compliant with the Bluetooth® Low Energy (BLE) SIG specification v5.0 and with IEEE 802.15.4-2011 board. It integrates an ARM Cortex-M4 STM32WB55RG microcontroller with 256KB of RAM and 1MB of ROM Flash.

Flashing the device
Flashing the Board Using OpenOCD
The ST p-nucleo-wb55 board includes an on-board ST-LINK programmer and can be flashed using OpenOCD (use version 0.11.0 at least).
To flash this board, just use the following command:
Flashing the Board Using ST-LINK Removable Media
On-board ST-LINK programmer provides via composite USB device removable media. Copying the HEX file causes reprogramming of the board. This task could be performed manually; however, the cpy2remed (copy to removable media) PROGRAMMER script does this automatically. To program board in this manner, use the command:
- Note
- This PROGRAMMER was tested using ST-LINK firmware 2.37.26. Firmware updates could be found on this STM webpage.
Accessing RIOT shell
Default RIOT shell access utilize VCP (Virtual COM Port) via USB interface, provided by integrated ST-LINK programmer. In default configuration ST-LINK is connected to the microcontroller USART1. For more details See table 7, page 33 in board User Manual.
The default baud rate is 115 200.
