Compared to ST-LINK/V2 the changes are listed below. The new features supported on ST-LINK/V2-1 are: • USB software reenumeration • Virtual Com port interface on USB • Mass storage interface on USB • USB power management request for more than 100 mA power ...
UM1907 12/49 DocID027942 Rev 3 6.1.2 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 new functionality, bug fixes, support for new microcontroller families), it is recommended to visit www.st.com before starting to use the STM32F746G-DISCO board and periodical ...
13/49 UM1907 Hardware layout and configuration 48 • 5V DC power with limitation from CN14, the USB type mini-B connector of ST-LINK/V2-1 (USB 5V power source on silkscreen of JP1 (5V link)). It is the default setting. If the USB enumeration succeeds (as explained below), the ST-LINK 5V link power is enabled, by asserting the PWR_ENn signal. This pin is connected to a power switch (ST890), which powers the board. This power switch featur ...

15/49 UM1907 Hardware layout and configuration 48 1. If more than 500 mA current is needed by the board, the PC may be damaged or current can be limited by the PC. As a consequence the board is not powered correctly. 2. 500 mA will be requested at the enumeration, so there is a risk that the request is rejected and enumeration does not succeed if the PC cannot provide such current. 6.4 Clock sources Up to 3 clock sources as described belo ...
UM1907 16/49 DocID027942 Rev 3 6.7 USB OTG FS The STM32F746G-DISCO discovery board supports USB OTG full speed communication via a USB micro-AB connector (CN13) and USB power switch (U6) connected to VBUS. The discovery board can be powered by this USB connection at 5V DC with 500mA current limitation. A green LED LD5 will be lit in one of these cases: • Power switch (U6) is ON and STM32F746G-DISCO works as an USB host � ...
