6.7.2 ST-LINK/V2-1 firmware upgrade
For its own operation, ST-LINK/V2-1 employs a dedicated MCU with Flash memory. Its firmware determines ST-
LINK/V2-1 functionality and performance. The firmware may evolve during the life span of
STM32MP157x-EV1 to
include new functionality, fix bugs or support new target microcontroller families. It is therefore recommended to
keep ST-LINK/V2-1 firmware up to date. The latest version is available from www.st.com.
