STM32 Nucleo U5A5ZJ-Q Type-C

[Fega]

Hello,

 

I have an ST Nucleo U5A5ZJ-Q board. I am powering the board through the CN1 connector and using the ST-LINK at the same time.

In the project I am working on, I would like to connect a USB device to the hardware. For this purpose, I want to use the USB Type-C connector.

When I connect the sensor to the Type-C connector, it does not receive any power. My assumption is that I cannot power the device through the USB Type-C connector. Also, LD7 does not light up.

I wanted to consult you about this before doing anything that might damage the board.

In addition I use usb standalone(STM32Cube FW_U5 V1.8.0).

Thank you in advance for your support.

 

Best Regards,

Faruk

Hi,

see board circuit:

https://www.st.com/resource/en/schematic_pack/mb1549-u5a5ziq-c04-schematic.pdf

5V_ucpd needs power:

+

you have to set jumpers: 1-2 , if st-link should give the power ; + 7-8 for 5V_ucpd

+

your software has to run the USB-host , to check a connected device; 

MSC host for connecting an usb-stick, etc. for other devices

What sensor, exactly ?

Have you implemented suitable USB Host code for it (or USB Device code, if this sensor is the Host) ?
