Hello everyone,
After successfully built the USB-C PD application with STM32U575Qll + TCPP0203 + BMS. Now I’m trying to establish USB communication between my STM32U575Qll board(USB-C) and Win10(USB2).
I have created the Ux_Device_CDC_ECM project and referenced the example as below:
https://github.com/STMicroelectronics/STM32CubeU5/tree/main/Projects/STM32U575I-EV/Applications/USBX/Ux_Device_CDC_ECM
When the board has been connected to the PC(win10), the Device Manager re-flash when USB2 plug in/out. However, it’s not being recognized as any device in the Device Manager.
I have checked USB-C DP/DM signal level by setting PA11/PA12 as GPIO_OutPut and checked VDDUSB(3.3V), VBUS(5V). I haven't find any hardware issue.
I will be very appreciative if someone could help me on how to solve this problem.
Thanks in advance.
Robert
