Support for UCPD with N6 with zephyr

Brenden_PLUS · ‎2025-11-25

I'm curious how hard of a task would it be to get UCPD working with the STM32N6 with zephyr.

I see it's supported with the G0

From my understanding the UCPD hardware block is the same between the two chips?

Differences mainly lie in number of peripheral instances and clock/reset bus architecture, not in core functionality. Also, note that, minor silicon revisions and optimizations may exist between these 2 families.

Thanks for the info

I decided not to go down the road of linking the address to the device tree to try it.

Currently Zephyr and USB c is kind of the bare minimum. You can see the github issue list here.

But it's mostly the bare minimum. To minimum for my needs.
