STM32H743 with USB C connector

[kmh011]

Hello there!

I've designed a board based on the STM32H743Zit Nucleo board, but unfortunately, I'm facing difficulties with the USB functionality. I'm unsure if it's a matter of configuration or firmware. When I tested USB settings and functionality using the Nucleo board, everything worked seamlessly. but in my costom board its not working and i donot have com port

Hello @kmh011 and welcome to the community,

If it was the same firmware tested on both boards (custom / Nucleo), most probably it's a hardware issue.

You need to share your schematics so others can help you efficiently.
