Overview
BOOTSelect
USB DFU or UART1 bootloader mode is available if switchS1 is in the “1” position.
Please slide the switch S1 to the right “1” and press the S2 RESET button to activate the
bootloader. The firmware detects automatically if a USB cable is present and enters into
DFU mode. If a USB cable is not present, the UART1 bootloader will be activated and it is
accessible via ST-Link’s VCOM. For more information about system bootloader please refer
to Application note AN2606.

RUTDevKit User Manual
MemorySelect
Since the STM32L5 MCUs have only one OSPI interface the RUTDevKit was
designed to use only one OSPI device at a time: OSPI PSRAM or QSPI NOR FLASH. Use
SW3 to select between these two devices. SW3 Switch selects CS signal available for MCUs
OSPI interface. Unused device’s CS pin remains pulled up to VCC, hence not selected state.
PowerSourceSelect
Four power sources are available in RUTDevKit:
1. ST-Link USB port.
2. SMPS powered from CAN FD, RS485, and USB Type C interfaces.
3. CR1220 coin battery socket.
4. Arduino connectors –configured using R23 and R27 0R 0402 resistors.
Select the power source using SW1 STLINK or SMPS. With SW2 users can select the
power source as BAT –coin battery or LDO 3.3V. LDO is powered from SW1 selected

power source.
ProgrammingUsingExternalConnector
Users may use third party programming devices to connect STM32L562 target via
P14 SWD connector. By default target, MCU is connected to ST-Link debugger. To use
external SWDport the solder bridges have to be disconnected: SB30, SB31, SB32.
CAN FD Sockets
Two Amphenol ICC Minitek MicroSpace™are used for CAN FD connection. Part No.:
10142344-104KLF . One for CAN input cable, another for CAN output cable. To connect the
wires certain receptacles are needed: 10142348-004LF and contacts 10141272-111LF have
to be crimped and mounted into the receptacle.

Fuses
Resettable and non-resettable fuses are used for this project. In case the fuses are
not fit for the user’s final application the user has to change the fuses by unsoldering and
soldering new ones that meet the requirements. Rev2 fuses list:

DemoFirmwareExamples
Default Application
The New board comes with already preprogrammed firmware. This firmware is used
for hardware testing/diagnostics. The whole testing process is monitored using
STM32CubeMonitor-UCPD software. Use the “TRACES” option to monitor outgoing
messages from ST-Link VCOM port.
How to use:
1. Have STM32CubeMonitor-UCPD installed on your Laptop/PC.
2. Launch STM32CubeMonitor-UCPD software.
3. Connect RUTDevKit to ST-Link’s Micro USB port.
4. Press the “RESET” button on the board and TRACESSelect ST-Link VCOM
in STM32CubeMonitor-UCPD software. Please do this step in 5 seconds.
5. The terminal window should show progress with all the tests beginning from
PSRAM Test as shown below:
