The LED LD10 is lit when the STM32479I-EVAL evaluation board is powered by the 5V
correctly.
Caution:
In order to avoid the impact of USB PHY and Ethernet PHY and get precise results of
current consumption on JP2, the following cautions need to be taken into account:
configure Ethernet PHY into Power Down Mode by setting low level of MFX
(MFX_GPIO13).
configure USB HS PHY into Low Power Mode (Register Address = 04, bit 6 in USB
PHY).
5.3 Clock
source
Five clock sources are available on STM32479I-EVAL evaluation board for
STM32F479NIH6 and RTC embedded.
X1, 25MHz Crystal with socket for STM32F479NIH6 Microcontroller, it can be removed
when internal RC clock is used.
X2, 32KHz Crystal for embedded RTC
X3, 24MHz Oscillator for camera module
X4, 25MHz Crystal with socket for Ethernet PHY.
X5, 24MHz Crystal for USB OTG2 HS PHY.
JP14
For power supply from USB OTG1 FS (CN13) to
STM32479I-EVAL
only,
JP14 is set as shown to the right:
For power supply from USB OTG2 HS (CN8) to
STM32479I-EVAL
only,
JP14 is set as shown to the right:
For power supply from
power supply jack
(CN19) to both STM32479I-EVAL and
daughterboard connected on CN5 and CN6, JP14 is set as shown to the right
(
daughterboard must not have its own power supply connected
)
