How close are you, and how can I help? It's been three or four years since I worked on an ST ARM core, but I do work in the embedded world all the time, and I'm happy to be of assistance. With a little bit of digging, I can probably even find my old ST background debug dongle and the tools to support it.
I presently have a strong interest in seeing this project through to completion. I have been standardizing my computer controlled systems on a Bigtreetech Manta M8P board, which basically is a breakout board for a Raspberry Pi CM4 with an ST32H723ZET6 on it to run the lower-level stuff. I've had very good luck with it using it for Klipper/Mainsail/Crowsnest to run a 3D printer. And since the stepper drivers I want to use to drive the motors on my milling machine drop right in, I'd like to bridge LinuxCNC to it. The higher current drivers (like variants of the TMC5160) use SPI, so I'd need that driver. And it'd be nice to be able to poll a few GPIO's so I can move the mill bed with a joystick for setup. But it shouldn't be *that* difficult, I don't think.
Just let me know if/how I can contribute.
