There was a problem hiding this comment.
Take it or leave it: I wonder if we might want to move the board-specific bits into submodules with #[cfg(feature = <board feature>] on them, instead of sticking a cfg attribute on each function and constant? We could do the same for the existing F3 stuff. The code might read a little nicer that way. But, it's up to you.

That sounds like a good follow-up PR. I just wanted to share what I'd done to make it run on the board I had.

On this new board, we get the user-led task to drive the LEDs via the
stm32xx-systask, like it did on the STM32H7 based boards.This PR also updates the existing STM32F4-DISCOVERY support in the
user-ledtask (which uses the STM32F407) to also use thestm32xx-systask for driving LEDs. This leaves just the STM32F3-DISCOVERY using the direct-access approach.The STM32 UART support also now understands both the F429 and F407, but I didn't yet hook up a terminal to see if it works.
The demo was tested on a NUCLEO-STM32F429ZI. Unfortunately I don't have a STM32F4-DISCOVERY to hand to check I didn't break anything there.
This was literally my first introduction to Hubris, so hopefully I got it all mostly right. The changes took about five hours, all told. Much of that was diagnosing the
stm32xx-sysconstantly restarting - it was because it didn't have permission to write to the GPIO address range.
