Dear STM32U585AIIXQ Community,
I recently acquired an STWIN.box development board and have been attempting to establish a communication link with my computer via the USB interface. Unfortunately, my computer is not recognizing the COM port associated with the STWIN.box.
I Checked the Device Manager (Windows): After installing the USB driver, I opened the Device Manager on my Windows computer to verify if the STM32 COM port is detected, but unfortunately, it is not appearing in the list of Ports (COM & LPT).
Despite these efforts, I am still unable to establish a connection between my STWIN.box and my computer. I am seeking assistance from the community to help me identify the potential causes of this issue and find a suitable solution.
Has anyone encountered a similar problem with the STWIN.box not being recognized as a COM port on Windows? If so, how did you resolve it? Are there any additional troubleshooting steps that I should follow to ensure successful communication between the STWIN.box and my computer?
Note: on windows 10
Your guidance and expertise in this matter would be greatly appreciated
Thank you for your quick reply.
I've already done it, in order to flash the bin file in the STWIN.box. Currently, I'm working on predictive maintenance and I'm using NanoEdge Studio to generate Librairy AI. I do it using the tutorial (link) but when I want to start data logging by importing from SERIAL (USB), the STWIN.box COM is not displayed on the interface (image 1). According to the tutorial, when you open the Windows computer's Device Manager, the STM32's COM port should appear in the list of ports (COM & LPT). However, this is not the case. (image 2)
Windows does see the board as some USB device (so USB works, cable is ok...) - but it is not a CDC class device (COM port). Try View -> Devices by container to see if the firmware exposes other USB functions. If not, then the firmware simply does not implement a CDC function. Review the firmware.
(by the way, the STWIN.box documentation does not say almost anything about the USB/C, it is not shown on the schemas. Is this a NDA information?)
