Step 6. Plug a Source application board on the X-NUCLEO-SNK1M1 expansion board CN1 connector through
a Type-C cable and refer to the following LED operation description to identify the application results:
–
NUCLEO-G071RB LD3 LED is ON when the board is supplied by the ST-LINK micro-USB
connector (CN1)
– X-NUCLEO-SNK1M1 LD2 LED is ON when the 3V3 voltage is provided to the expansion board
by the STM32 Nucleo
– X-NUCLEO-SNK1M1 LD1 LED is ON when a Source is connected to the USB Type-C CN1
connector and the V
BUS
is provided
– NUCLEO-G071RB LD4 LED:
◦ blinks once every 2 seconds when USB default (up to 500 mA) is identified
◦ blinks twice every 2 seconds when a Source USB Type-C 1.5 A current capability is
identified;
◦ blinks 3 times every 2 seconds when a Source USB Type-C 3 A current capability is
identified;
◦ is ON when the explicit negotiation between the two contractors is reached.
1.3.1.1.1 Dead battery operation mode
Step 1. Repeat steps 1- 4 described in Section 1.3.1.1
Step 2. Disconnect the micro-USB cable from NUCLEO-G071RB CN1.
Step 3. Remove the power selection jumper from the JP2 header on NUCLEO-G071RB development board
(previously set on STLK 1-2 pins) and leave it fully open.
Step 4. On the X-NUCLEO-SNK1M1 , set LDO OUT jumper (JP3) and NRST jumper (JP4).
Step 5. Plug a Source board to X-NUCLEO-SNK1M1 CN1 connector through a Type-C cable.
The provided V
BUS
supplies the Sink solution while the LEDs define the status as previously described.
1.3.1.2 Running the demo application with NUCLEO-G474RE development board
The NUCLEO-G474RE development board embeds the STM32G474RE microcontroller with the UCPD and
USB2.0 data peripherals. To run the application demo with the NUCLEO-G474RE , powering the system via
ST-LINK micro-USB connector, follow the procedure below.
Step 1. Check the jumper is closed on the development board JP5 header, 5V_STLK 1-2 pins.
Step 2. On the X-NUCLEO-SNK1M1 expansion board, fit CC1 JP1 and CC2 JP2 jumpers on position 1-2.
Step 3. Plug the expansion board on top of the STM32 Nucleo and leave J3 and J4 headers open.
Step 4. Connect the NUCLEO-G474RE micro-USB connector (CN1) to the PC/laptop.
The board appears as a virtual disk (NODE_G474RE).
Step 5. Program the STM32G474RE by dragging and dropping the binary file corresponding to the board
(G4_SNK1M1_Consumer.bin) to the virtual disk.
STM32 Nucleo LD1 LED blinks red and green for few seconds. When the LED stops blinking, the
programming operation is complete and the demo is ready.
