ST-LINK/V2-1 firmware upgrade
The ST-LINK/V2-1 embeds a firmware upgrade mechanism for 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 keep the ST-LINK/V2-1 firmware up to date before starting to use the
STM32 Nucleo-144 board. The latest version of this firmware is available from the
www.st.com
website.
6.3.3
Using the ST-LINK/V2-1 to program and debug the on-board STM32
To program the on-board STM32, place the two jumpers marked in red on the connector
CN4, as shown in
Figure 9
. The CN6 connector must not be used, since it could disturb the
communication with the STM32 microcontroller of the Nucleo-144 board.
