Since the current consumption of the STM32MP157x-EV1 Evaluation board exceeds the permissible current on
the USB, it is not possible to power the board through the ST-LINK/V2-1 USB. To use the ST-LINK/V2-1 for
programming and debugging, it is mandatory to power the board first using the 5 V power supply, then connect
the ST-LINK/V2-1 USB cable to the PC. Proceeding this way, the USB enumeration succeeds with the support of
the external power source.
The user must respect the following power sequence procedure:
1.
Check that MB1263/JP1 is OFF, MB1263/JP4 [2-3] and JP5 [2-3] are ON to connect UART4 as ST-
LINK VCP.
2.
Connect the 5 V power source, MB1263/LD1 LED turns green, MB1263/LD6 LED flashes red.
3.
Connect the PC to USB connector MB1263/CN4, MB1263/LD6 LED is red and becomes green once the
connection with the ST-LINK is established.

Drivers
The ST-LINK/V2-1 requires a dedicated USB driver, which, for Windows 7
®
, Windows 8
®
and Windows 10
®
, is
.
In case the STM32MP157x-EV1 Evaluation board is connected to the PC before the driver is installed, some
of its interfaces may be declared as
“Unknown”
in the PC device manager. In this case, the user must install
the dedicated driver files, and update the driver of the connected device from the device manager as shown in
.
Note:
Prefer using the USB Composite Device handle for a full recovery.
