UM2535 ETM TRACE Mictor-38 connector Figure 9. USB composite device 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 STLINK/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.
