STM32WB55 SWIM Usage

[aemen_mohsin]

I have just downloaded the reference board from the STM32WB55: STM32WB55RG - Ultra-low-power dual core Arm Cortex-M4 MCU 64 MHz, Cortex-M0+ 32 MHz with 1 Mbyte of Flash memory, Bluetooth LE 5.4, 802.15.4, Zigbee, Thread, Matter, USB, LCD, AES-256 - STMicroelectronics under the board manufacturing specifications. In the schematic, there is only a mention of USB ports for the chip at pins PA11 and PA12. I am actually planning on using ST-link to program the chip and needed help on seeing which pins I can add this to and what components are needed for this. I am new to STM microcontrollers and would really appreciate the help.

Hello @aemen_mohsin and welcome to the ST Community 😊.

As a debugger/programmer for the STM32WB55RG, you can use the ST-LINK/V2 or STLINK-V3SET .

to understand how to connect the ST-LINK to your MCU, you can use the UM2448 (for STLINK-V3SET) or the UM1075 (for ST-LINK/V2) and the DS11929 for the MCU pinout.
