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-G474RE 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 VBUS is provided
– NUCLEO-G474RE LD2 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;
◦ blinks 4 times every 2 seconds when the explicit negotiation between the two contractors is
reached;
◦ turns ON when the explicit negotiation between the two contractors is reached and the
USB2.0 data connection is established.
1.3.1.2.1 Dead battery operation mode
Step 1. Repeat steps 1- 4 described in Section 1.3.1.2
Step 2. Disconnect the micro-USB cable from NUCLEO-G474RE CN1.
Step 3. Remove the power selection jumper from the JP2 header on NUCLEO-G474RE 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.
1.3.1.3 Running the demo application with NUCLEO-L412RB-P development board
The NUCLEO-L412RB-P development board embeds the STM32L412RB microcontroller which includes the
USB2.0 data peripheral only. The application example demonstrates that the TCPP01-M12 protection can be
matched with microcontrollers which does not include the UCPD peripheral to implement a Type-C Sink port only,
thus exploiting the microcontroller ADC peripherals to monitor the current capabilities of the Source. To run the
application demo with the
NUCLEO-L412RB-P , 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-L412RB-P micro-USB connector (CN1) to the PC/laptop.
The board appears as a virtual disk (NODE_L412RB).
Step 5. Program the STM32L412RB by dragging and dropping the binary file corresponding to the board
(SNK1M1_Consumer_TypeC_Only.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.
