That's really interesting! I haven't looked much into any of the new Cortex M33 chips since all the CMSIS stuff is Apache 2 licensed. I wonder if anyone has clean-room made their own. Seems like an enormous task.

Too bad there wasn't a Pi Pico with a Cortex M4 and tons of RAM. Would be excellent.

I could do what a lot of other projects do and just git submodule the CMSIS and HAL stuff, but I would like the OS to be as self-contained as possible. I'll keep thinking about this..

Oh, and new release is on the 11th. Get any bug fixes in asap.
