6.3 Embedded ST-LINK/V2-1
The ST-LINK/V2-1 programming and debugging tool is integrated into the STM8 Nucleo-32 board.
For detailed information about the debugging and programming features of ST-LINK/V2-1, refer to the
ST-LINK/V2
in-circuit debugger/programmer for STM8 and STM32 user manual ( UM1075 ) and Overview of ST-LINK
derivatives technical note ( TN1235 ).
Features supported by the ST-LINK/V2-1:
•
USB software re-enumeration
• Virtual COM port interface on USB
• Mass storage interface on USB
• USB power management request for more than 100 mA power on USB
Features not supported on ST-LINK/V2-1:
•
SWIM interface
The embedded ST-LINK/V2-1 is directly connected to the SWIM port of the target STM8.
6.3.1 Drivers
The ST-LINK/V2-1 requires a dedicated USB driver, which, for Windows 7
®
, Windows 8
®
and Windows 10
®
, is
found at www.st.com .
In case the STM8 Nucleo-32 board is connected to the PC before the driver is installed, some STM8 Nucleo-32
interfaces may be declared as
“Unknown” in the PC device manager. In this case, the user must install the
dedicated driver files, and update the driver of the connected device from the device manager as shown in
Figure 7 .
Note: Prefer using the USB Composite Device handle for a full recovery.

6.3.2 ST-LINK/V2-1 firmware upgrade
The ST-LINK/V2-1 embeds a firmware mechanism for the in-situ upgrade through the USB port. As the firmware
may evolve during the lifetime of the ST-LINK/V2-1 product (for example new functionalities, bug fixes, support for
new microcontroller families), it is recommended to visit the
www.st.com website before starting to use the STM8
Nucleo-32 board and periodically, to stay up-to-date with the latest firmware version.
