Features dropped:

• SWIM interface

The USB connector CN21 is usable to power STM32L4R9I-EVAL regardless of the ST-LINK/V2-1 facility use for debugging or for flashing STM32L4R9AII6. This holds also when ST-LINK/V2 stand-alone tool is connected to CN12 or CN17 or CN11 or CN15 connector and used for debugging or flashing STM32L4R9AII6. Section 9.5 provides more detail on powering STM32L4R9I-EVAL. For full detail on both versions of the debug and flashing tool, the stand-alone ST-LINK/V2 and the embedded ST-LINK/V2-1, refer to www.st.com.

9.3.1 Drivers

Before connecting STM32L4R9I-EVAL to a Windows (XP, 7, 8 10) PC via USB, a driver for ST-LINK/V2-1 must be installed. It is available from www.st.com.

In case the STM32L4R9I-EVAL board is connected to the PC before installing the driver, the Windows device manager may report some USB devices found on STM32L4R9I-EVAL as “Unknown”. To recover from this situation, after installing the dedicated driver downloaded from www.st.com, the association of “Unknown” USB devices found on STM32L4R9I-EVAL to this dedicated driver must be updated in the device manager manually. It is recommended to proceed using USB Composite Device line, as shown in

Figure 8.

Figure 8. USB composite device

9.3.2 ST-LINK/V2-1 firmware upgrade

For its own operation, ST-LINK/V2-1 employs a dedicated MCU with Flash memory. Its firmware determines ST-LINK/V2-1 functionality and performance. The firmware may evolve during the life span of STM32L4R9I-EVAL to include new functionality, fix bugs or support new target microcontroller families. It is therefore recommended to keep ST-LINK/V2-1 firmware up to date. The latest version is available from www.st.com.

9.4 ETM trace

The connector CN12 is available to output trace signals used for debug. By default, the evaluation board is configured such that, STM32L4R9AII6 signals PE2, PE5 and PE6 are not connected to trace outputs Trace_CK, Trace_D2, and Trace_D3 of CN12. They are used for other functions.

Warning: Enabling the CN12 trace outputs through hardware modifications described in

Tabl e 1 results in reducing the memory address bus width to 20 address lines and so the

addressable space to 1 Mwords of 16 bits. As a consequence, the on-board SRAM and NOR Flash memory usable capacity is reduced to 16 Mbits.

9.5 Power Supply

The STM32L4R9I-EVAL board is designed to be powered from 5 V DC power source. It incorporates a precise polymer Zener diode (Poly-Zen) protecting the board from damage due to wrong power supply. One of the following four 5 appropriate board configuration:

• Power jack CN18, marked PSU_DC5V on the board. A jumper must be placed in E5V location of JP11. The positive pole is on the center pin as illustrated in Figure 20.

• Micro-B USB receptacle CN21 of ST-LINK/V2-1, provides up to 500mA to the board. Offering enumeration feature described in Section 9.5.1.

• Micro-AB USB receptacle CN3 of USB OTG interface, marked USB OTG_FS on the board, supplies up to 500mA to the board.

• Pin 39 of CN5 and Pin 39 of CN6 extension connectors for custom daughterboard, marked D5V on the board.

9.5.1 Supplying the board through ST-LINK/V2-1 USB port

To power STM32L4R9I-EVAL in this way, the USB host (a PC) gets connected with the STM32L4R9I-EVAL board’s Micro-B USB receptacle, via a USB cable. This event starts the USB enumeration procedure. In its initial phase, the host’s USB port current supply capability is limited to 100 mA. It is enough because only ST-LINK/V2-1 part of STM32L4R9I-EVAL draws power at that time. If the solder bridge SB33 is open, the U22 ST890 power switch is set to OFF position, which isolates the remainder of STM32L4R9IEVAL from the power source. In the next phase of the enumeration procedure, the host PC informs the ST-LINK/V2-1 facility of its capability to supply up to 300 mA of current. If the answer is positive, the ST-LINK/V2-1 sets the U22 ST890 switch to ON position to supply power to the remainder of the STM32L4R9I-EVAL board. If the PC USB port is not capable of supplying up to 300 mA of current, the CN18 power jack is available to supply the board.

Should a short-circuit occur on the board, the ST890 power switch protects the USB port of the host PC against a current demand exceeding 600 mA, In such an event, the LD8 LED lights on.

The STM32L4R9I-EVAL board is also supply-able from a USB power source not supporting enumeration, such as a USB charger, as shown in power switch ON regardless of enumeration procedure result and passes the power unconditionally to the board.

The LD7 red LED turns on whenever the whole board is powered.

Table 2. ST-LINK/V2-1 turns the ST890

9.5.2 Using ST-LINK/2-1 along with powering through CN18 power jack

If the board requires more than 300 mA of supply current, this cannot be provided by host PC connected to ST-LINK/2-1 USB port, used for debugging or flashing STM32L4R9AII6. In such a case, the board is supplied through CN18 (marked PSU_DC5V on the board).

To do this, it is important to power the board before connecting it with the host PC, which requires the following sequence to be respected:

1. Set the jumper in JP11 header in E5V position

2. Connect the external 5 V power source to CN18

3. Check the red LED LD7 is turned on

4. Connect host PC to USB connector CN21

In case the board demands more than 300 mA and the host PC is connected via USB before the board is powered from CN18, there is a risk of the following events to occur, in the order of severity:

1. The host PC is capable of supplying 300 mA (the enumeration succeeds) but it does not incorporate any over-current protection on its USB port. It is damaged due to overcurrent.

2. The host PC is capable of supplying 300 mA (the enumeration succeeds) and it has a built-in over-current protection on its USB port, limiting or shutting down the power out of its USB port when the excessive current demand from STM32L4R9I-EVAL is detected. This causes an operating failure to STM32L4R9I-EVAL.

3. The host PC is not capable of supplying 300 mA (the enumeration fails) so ST-LINK/V21 does not supply the remainder of STM32L4R9I-EVAL from its USB port VBUS line.

The boot option is configured by setting switch SW1 (BOOT) and the boot base address programmed in the nBOOT1, nBOOT0 and nSWBOOT0 of FLASH_OPTR option bytes.

Switch Setting Description

SW1

Table 5. Boot selection switch

Default setting. BOOT0 line is tied low. STM32L4R9AII6 boots from main Flash

memory or system memory.

BOOT0 line is tied high. STM32L4R9AII6 boots from system Flash memory (nBOOT1 bit of FLASH_OPTR register is set high) or from RAM (nBOOT1 is set low).

9.8.1 Bootloader limitations

Boot from system Flash memory results in executing bootloader code stored in the system Flash memory protected against writing and erasing. This allows in-system programming (ISP), that is, flashing the STM32 user Flash memory. It also allows writing data into RAM. The data come in via one of communication interfaces such as USART, SPI, I2C bus, USB or CAN.

Bootloader version is identified by reading the Bootloader ID at the address 0x1FFF6FFE: the content is 0x91 for bootloader V9.1 and 0x92 for V9.2.

The STM32L4R9AII6 part soldered on the STM32L4R9I-EVAL main board is marked with a date code corresponding to its date of manufacturing. STM32L4R9AII6 parts with a date code prior or equal to week 37 of 2017 are fitted with bootloader V9.1 affected by the limitations to be worked around, as described hereunder. Parts with the date code starting from week 38 of 2017 contain bootloader V9.2 in which the limitations no longer exist.

To locate the visual date code information on the STM32L4R9II6 package, refer to its datasheet (DS12023) available at www.st.com, section Package Information. Date code related portion of the package marking takes Y WW format, where Y is the last digit of the year and WW is the week. For example, a part manufactured in week 38 of 2017 bares the date code 7 38.

There is also another mean to identify the need for workaround: before opening the blister of the Discovery Kit, just check the back side of the blister. At the bottom left side, if the reference number is equal or higher than 32L4R9IDISCO/ 02-0, it means the bootloader version is V9.2 and there is no need to apply workaround. Any other inferior number like 01-0 will need the workaround.

Bootloader ID for the bootloader V9.1 is 0x91.

The following limitation exists in the bootloader V9.1:

Some user Flash memory data get corrupted when written via SPI interface

Description:

During bootloader SPI Write Flash operation, some random 64-bits (2 double-words) may be left blank at 0xFF

Workarounds:

WA1: add a delay between sending Write command and its ACK request. Its duration should be the duration of the 256-Byte Flash write time.

WA2: read back after each write operation (256 bytes or at end of user code flashing) and in case of error start write again.

WA3: Using bootloader, load a patch code in RAM to write in Flash memory through same Write Memory write protocol as bootloader (code provided by ST). The patch code is available for download from www.st.com website with a readme.txt file containing usage instructions.

9.9 Audio

A codec connected to STM32L4R9AII6 SAI interface supports DSAI port TDM feature. This offers STM32L4R9AII6 the capability to simultaneously stream two independent stereo audio channels to two separate stereo analog audio outputs.

There are two digital microphones on STM32L4R9I-EVAL board.

9.9.1 Digital microphones

U30 and U31 on STM32L4R9I-EVAL board are MP34DT01TR MEMS digital omnidirectional microphones providing PDM (pulse density modulation) outputs. To share the same data line, their outputs are interlaced. The combined data output of the microphones is directly routed to STM32L4R9AII6 terminals, thanks to the integrated input digital filters. The microphones are supplied with programmable clock generated directly by STM32L4R9AII6.

As an option, the microphones is connected to U26, Wolfson audio codec device, WM8994. In that configuration, U26 also supplies the PDM clock to the microphones.

Regardless of where the microphones are routed to, STM32L4R9AII6 or WM8994, their power supplier is either VDD or MICBIAS1 output of the WM8994 codec device.

Tabl e 6 shows settings of all jumpers associated with the digital microphones on the board.

9.9.2 Headphones outputs

The STM32L4R9I-EVAL board potentially drives two sets of stereo headphones. Identical or different stereo audio content are played back in each set of headphones. STM32L4R9AII6 sends up to two independent stereo audio channels, via its SAI1 TDM port, to the WM8994 codec device. The codec device converts the digital audio stream to stereo analog signals. It then boosts them for direct drive of headphones connecting to 3.5 on the board, CN24 for Audio-output1 and CN23 for Audio_output2.

The CN23 jack takes its signal from the output of the WM8994 codec device intended for driving an amplifier for loudspeakers. A hardware adaptation is incorporated on the board to make it compatible with a direct headphone drive. The adaptation consists of coupling capacitors blocking the DC component of the signal, attenuator and anti-pop resistors. The loudspeaker output of the WM8994 codec device must be configured by software in linear mode called “class AB” and not in switching mode called “class D”.

The I²C-bus address of WM8994 is 0b0011 010x.

mm stereo jack receptacles

9.9.3 Limitations in using audio features

Due to the share of some terminals of STM32L4R9AII6 by multiple peripherals, the following limitations apply in using the audio features:

• If the SAI1_MCLKA and SAI1_FSA are used as part of SAI1 port, it cannot be used as

CAN peripheral.

• If the SAI1_SDB is used as part of SAI1 port, it cannot be used as Comp2_OUT signal.

• If the SAI1 port of STM32L4R9AII6 is used for streaming audio to the WM8994 codec

IC, STM32L4R9AII6 cannot control the motor.

• If the digital microphones are attached to STM32L4R9AII6, control the motor cannot be

driven.

9.10 USB OTG FS port

The STM32L4R9I-EVAL board supports USB OTG full-speed (FS) communication. The USB OTG connector CN3 is Micro-AB type.

9.10.1 STM32L4R9I-EVAL used as USB device

When a “USB host” connection to the CN3 Micro-AB USB connector of STM32L4R9I-EVAL is detected, the board starts behaving as “USB device”. Depending on the powering capability of the USB host, the board potentially takes power from VBUS terminal of CN3. In the board schematic diagrams, the corresponding power voltage line is called U5V.

Section 9.5 provides information on how to set associated jumpers for this powering option.

The resistor R23 must be left open to prevent STM32L4R9I-EVAL from sourcing 5 V to VBUS terminal, which would cause conflict with the 5 if the MFX_GPIO6 is controlled by the software of the MFX MCU such that, it enables the output of U2 power switch.

9.10.2 STM32L4R9I-EVAL used as USB host

When a “USB device” connection to the CN3 Micro-AB USB connector is detected, the STM32L4R9I-EVAL board starts behaving as “USB host”. It sources 5

terminal of CN3 Micro-AB USB connector to power the USB device. For this to happen, the STM32L4R9AII6 sets the U2 power switch STMPS2151STR to ON state. The LD6 green LED marked OTG_FS indicates that the peripheral is supplied from the board. The LD5 red LED marked FS_OC lights up if over-current is detected. The resistor R23 must be closed to allow the MFX_GPIO6 from MFX MCU to control the U2 power switch.

In any other STM32L4R9I-EVALpowering option, the resistor R23 must be open, to avoid accidental damage caused to an external USB host.

9.10.3 Limitations in using USB OTG FS port

The USB OTG FS port operation is exclusive with motor control

9.10.4 Operating voltage

The USB-related operating supply voltage of STM32L4R9AII6 (VDD_USB line) must be within the range from 3.0

V to 3.6 V.

9.11 RS232 port

The STM32L4R9I-EVAL board offers one RS-232 communication port. The RS-232 communication port uses the DB9 male connector CN7. RX, TX, RTS and CTS signals of LPUSART1 port of STM32L4R9AII6 are routed to CN7.

9.11.1 Operating voltage

The RS-232 operating supply voltage of STM32L4R9AII6 (VDD line) must be within the range from 1.71

V to 3.6 V.

9.12 microSD card

Gbytes) and SDHC (up to 32 Gbytes) cards. One 8-Gbyte microSD card is delivered as part of STM32L4R9I-EVAL. The card insertion switch is routed to the MFX_GPIO5 of MFX MCU port.

9.12.1 Limitations

Due to the share of SDIO port, the following limitations apply:

• The microSD card cannot be operated simultaneously with motor control.

• The microSD card cannot be operated for 4 bits date when SDIO_D1 and SDIO_D2

used as Trace_D0 and Trace_D1 signals.

9.12.2 Operating voltage

The supply voltage for STM32L4R9I-EVAL microSD card operation must be within the range from 2.7

V to 3.6 V.

PA4 is routed to the two-way header CN4 allowing to fetch signals to or from PA4 or to ground it by fitting a jumper into CN4.

Parameters of the ADC input low-pass filter formed with R31 and C21 are adjustable by replacing these components according to application requirements. Similarly, parameters of the DAC output low-pass filter formed with R32 and C21 are modifiable by replacing these components according to application requirements.

The VREF+ terminal of STM32L4R9AII6 is used as reference voltage for both ADC and DAC. By default, it is routed to VDDA through a jumper fitted into the two-way header CN10. The jumper is removable and an external voltage applied to the terminal 1 of CN10, for specific purposes.
