32. EVAL evaluation board can be powered from ST LINK V2 1 USB connector CN21 U5V only when the 5 7 LCD is disconnected otherwise power consumption exceeds 300mA When the board is connected to USB port only the ST LINK V2 1 is powered for the USB enumeration because host PC only provides 100 mA max to the board at that time During the USB enumeration STM32756G EVAL board requires 300 mA power from the host PC If the host PC is able to provide the required power the enumeration succeeds and the power transistor U17 ST890 is switched ON the red LED LD10 is turned ON thus STM32756G EVAL evaluation board can consume no more than 300 mA of current If the host PC is not able to provide the requested current the enumeration fails Therefore the ST890 U17 remains OFF so consequently 3 3 V domain of the board and MCU will not be powered As a consequence the red LED LD10 remains turned OFF In this case it is mandatory to use an external power supply as extra power supply E5V from PSU or D5V must be used as external power supply in case current consumption of STM32756G EVAL evaluation board exceeds the allowed current on USB In this condition it is still possible to use USB for communication for programming or debugging only but it is mandatory to power the board first using E5V or D5V then connecting the USB cable to the PC Proceeding this way ensures that the enumeration succeeds thanks to the external power source A DoclD027919

35. Rev 1 UM1903 Hardware layout and configuration The following power sequence procedure must be respected e Connect jumper JP13 for PSU or D5V side e Checkthat JP15 is removed e Connect the external power source to PSU or D5V daughterboard mounted e Checkred LED LD10 is turned ON e Connect the PC to USB connector CN21 If this order is not respected the board may be powered by VBUS first then E5V or D5V and the following risks may be encountered 1 If more than 300 mA current is needed by the board the PC may be damaged or current can be limited by PC As a consequence the board is not powered correctly 2 300 mA will be requested at enumeration since JP15 must be OFF so there is risk that request is rejected and enumeration does not succeed if the PC cannot provide such current Consequently the board is not powered the led LD10 remains OFF Note In case the board is powered by an USB charger there is no USB enumeration so the led LD10 remains set to OFF permanently and the board is not powered Only in this specific case the jumper JP15 needs to be set to ON to allow the board to be powered anyway but in any cases the current will be limited to 600 mA by U17 ST890 The power supply is configured by setting the related jumpers JP2 JP9 and JP13 as described in Table 1 Jumper JP2 Table 1 Power related jumpers Description JP2 is used to measure MCU current consumption manually by multimeter Defa
