How to port micropython to Renesas RA8D1?

[River1219]

Can I make modifications based on the existing Renesas boards in the current MicroPython repository, or do I need to rewrite all the code from scratch?

Ideally you should extend the existing Renesas port; it should be less work.

The part I'm not sure about is how similar is the RA8 to the existing RA4/6 - and that's in terms of using the ports/renesas-ra/ra HAL. I'm not sure if it would need to be tweaked (see the README) by the Renesas tooling.

But even if you do need to update that HAL then that'll almost certainly be much easier than creating a whole new port.

Renesas RA8 looks well supported in Zephyr. So most likely you can use the Zephyr port of MicroPython to target that board.
