Evaluation board with STM32F479NI MCU
Introduction
The STM32479I-EVAL evaluation board is a complete demonstration and development
platform for STMicroelectronics ARM®Cortex® -M4 core-based STM32F479NIH6
microcontroller. It features three I2C, six SPIs with two multiplexed full-duplex I2S interfaces,
SDMMC, four USARTs and four UARTs, two CANs, three 12-bit ADCs, two 12-bit DACs,
one SAI, 8 to 14-bit digital camera module interface, internal 320+4 Kbytes of SRAM and 2
Mbytes of Flash memory, USB HS OTG and USB FS OTG, Ethernet MAC, FMC interface,
MIPI DSI interface, Quad-SPI interface, Cryptographic acceleration, JTAG and ETM
debugging support. This evaluation board can be used as a reference design for user
application development but it cannot be considered as a final application.
The full range of hardware features on the board helps the user to evaluate all peripherals
(USB OTG HS, USB OTG FS, Ethernet, motor control, CAN, microSD Card, USART, Audio
DAC and ADC, digital microphone, IrDA, RF-EEPROM, SRAM, NOR Flash, SDRAM, 
Quad-SPI Flash, 4" TFT LCD with MIPI DSI interface and capacitive touch panel and
others) and to develop his own applications. Extension headers make it possible to easily
connect a daughterboard for specific application.
The integrated ST-LINK/V2-1 provides an embedded in-circuit debugger and programmer
for the STM32 MCU.

5.1 Embedded ST-LINK/V2-1
The ST-LINK/V2-1 programming and debugging tool is integrated on the STM32479I-EVAL
evaluation board. Compared to ST-LINK/V2 the changes are listed below.
The new features supported on ST-LINK/V2-1 are:
USB software re-enumeration
Virtual com port interface on USB
Mass storage interface on USB
USB power management request for more than 100mA power on USB
This feature is no more supported on ST-LINK/V2-1:
SWIM interface
For all general information concerning debugging and programming features common
between V2 and V2-1 refer to ST-LINK/V2 User Manual UM1075.
Note 1: It is possible to power the board via CN22 (Embedded ST-LINK/V2-1 USB connector) even
if an external tools is connected to CN12 (ETM Trace connector) or CN16 (External JTAG
and SWD connector).
Note 2: ETM can only work at 50MHz clock by default because ETM signals are shared with other
peripherals. If a best performance of ETM is required (84 MHz/98 MHz), R32, R34, R35,
R37, R38, R238, SB4, SB5, SB7, SB9, SB17, SB19 must be removed, to reduce the stub
on ETM signals. In this way SAI, Ethernet and Camera are not functional and NOR flash
and the address of the SRAM are limited on A18.
Note 3: ETM Trace function would be abnormal as SAI_SDB share same pins with TRACE_D0, and
TRACE_D0 would be forced high by SAI_SDB, so it is necessary to set (SAI_SDB)
ADCDAT1 pin of audio codec WM8994ECS/R (U23) to be tri-state by software when using
ETM Trace.
5.1.1 Drivers
The ST-LINK/V2-1 requires a dedicated USB driver, which can be found on www.st.com for
Windows XP, 7 and 8.
In case the STM32479I-EVAL evaluation board is connected to the PC before the driver is
installed, some STM32479I-EVAL interfaces may be declared as "Unknown" in the PC
device manager. In this case the user must install the driver files, and update the driver of
the connected device from the device manager.
Note: Prefer using the “USB Composite Device” handle for a full recovery.

Hardware Layout and configuration UM1935
12/77 DocID028194 Rev 1
Figure 4. Updating the list of drivers in device manager
1. Prefer using the “USB Composite Device” handle for a full recovery.
5.1.2 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 STM32479I-EVAL board and
periodically, in order to stay up-to-date with the latest firmware version.
5.2 Power Supply
STM32479I-EVAL evaluation board is designed to be powered by 5V DC power supply and
is protected by PolyZen from wrong power plug-in event. It’s possible to configure the
evaluation board to use any of following six sources for the power supply.
5V DC power adapter connected to CN19, the Power Jack on the board (Power Supply
Unit on silk screen of JP14(PSU)).
5V DC power with 300mA limitation from CN22, the USB type B connector of ST-
LINK/V2-1 (USB 5V power source on silkscreen of JP14(STlk)). If the USB
enumeration succeeds (as explained below), the ST-LINK U5V power is enabled, by
asserting the PWR_EN pin. This pin is connected to a power switch (ST890), which
powers the board. This power switch features also a current limitation to protect the PC
in case of short-circuit on board. If over current (more than 600mA) happens on board,
the LED LD11 is lit.
5V DC power with 500mA limitation from CN8, the USB OTG2 HS Micro-AB connector
(USB 5V power source on silkscreen of JP14 (HS)).
5V DC power with 500mA limitation from CN13, the USB OTG1 FS Micro-AB
connector (USB 5V power source on silkscreen of JP14 (FS1)).
5V DC power with 500mA limitation from CN14, the USB OTG2 FS Micro-AB
connector (USB 5V power source on silkscreen of JP14 (FS2)).
5V DC power from CN5 and CN6, the extension connectors for daughterboard
(daughterboard power source on silkscreen of JP14 (D5V)).
STM32479I-EVAL evaluation board can be powered from ST-LINK USB connector CN22
(U5V), but only ST-LINK circuit has the power before USB enumeration, because host PC
only provides 100mA to the board at that time. During the USB enumeration, STM32479I-
EVAL board asks for the 300mA power to the host PC. If the host is able to provide the

DocID028194 Rev 1 13/77
UM1935 Hardware Layout and configuration
76
required power, the enumeration succeeds, the power transistor U18 (ST890) is switched
ON, the red LED LD10 is turned ON, thus STM32479I-EVAL board is powered and can
consume maximum 300mA current, but not more. If the host is not able to provide the
requested current, the enumeration fails. Therefore the ST890 (U18) 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 can be used as external power supply in case current consumption
of STM32479I-EVAL 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.
The following power sequence procedure must be respected:
1. Connect jumper JP14 for PSU or D5V side
2. Check that JP20 is removed
3. Connect the external power source to PSU or D5V (daughterboard mounted)
4. Check red LED LD10 is turned ON
5. Connect the PC to USB connector CN22
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 300mA 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. 300mA will be requested at enumeration (since JP20 must be OFF), so there is risk that
request is rejected and enumeration does not succeed if PC can’t provide such current.
Consequently the board is not powered (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 JP20 needs to be set to ON, to allow the board to be powered anyway.
The power supply is configured by setting the related jumpers JP2, JP10 and JP14 as
described in Table 1: Power related jumpers.

5.8 USB OTG2 HS and FS
STM32479I-EVAL evaluation board supports USB OTG2:
High speed communication via a USB Micro-AB connector (CN8), USB High speed
PHY (U8) for high speed function.
Full speed communication via another USB Micro-AB connector (CN14).
The evaluation board can be powered by these USB connectors (CN8 or CN14) at 5V DC
with 500mA current limitation.
As several OTG2 FS signals are shared with OTG2 HS ULPI bus, so some settings are
needed, when using OTG2 FS (CN14) shown in Table 7: USB OTG2 function configuration.
A USB power switch (U7) is also connected on VBUS and provides power to either:
CN8 (with SB13 and SB16 closed and SB14 and SB15 open)
CN14 (with SB14 and SB15 closed and SB13 and SB16 open).
Green LED LD5 (for CN8) or LD9 (for CN14) will be lit when either:
Power switch (U7) is ON and STM32479I-EVAL works as an USB host
VBUS is powered by another USB host when STM32479I-EVAL works as an USB
device.
Red LED LD6 will be lit when over-current occurs (IVBUS > 500 mA).
5.9 RS232 and IrDA
RS232 and IrDA communication is supported by D-type 9-pins RS232 connector CN7, and
IrDA transceiver U1, which is connected to USART1 of STM32F479NIH6 on STM32479I-
EVAL evaluation board. The signals Bootloader_RESET and Bootloader_BOOT0 are added
on RS232 connector CN7 for ISP support.
USART1 of STM32F479NIH6 is shared with RS232/IrDA and ST-LINK/V2-1 controller. 
Its communication can be changed by setting JP15 and JP19.
