10.1.2 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 life time of the ST-LINK/V2-1 product (for
example a new functionality, bug fixes, support for new microcontroller families), it is
recommended to visit the www.st.com website before starting to use the STM32L476
Discovery board and periodically, in order to stay up-to-date with the latest firmware version.
10.1.3 Using ST-LINK/V2-1 to program/debug the STM32L476VGT6
on board
To program the STM32L476VGT6 on board, simply plug in the two jumpers on CN3, as
shown in
Figure 6 in red, and connect the STM32L476 Discovery board to the PC through
the Mini-B USB ST-LINK/V2-1 CN1 connector.
Make sure the jumpers JP3, JP6.3V3, and JP5.ON are set.
Do not use the CN4 connector.
