Inferno on Pi Pico 2?

[David Boddie]

Has anyone started or considered starting a port of Inferno to the new
Pi Pico 2?

With 520KB RAM and 4MB flash, plus some support for double precision
floating
point operations, it should be capable of running a small Inferno
system.
The SoC has some documentation here:

Here's some more background reading and opinion:

Considered it, yes.  Particularly the RISC-V part makes an interesting target.

Interesting.

The Sparkfun RP2350 Pro has 8MB PSRAM: https://www.sparkfun.com/rp2350#specs

It's a similar story with the Pimoroni Pico Plus 2:

I will be giving it a try when I get one.

I expect/hope that you will have the easiest time porting Inferno based on your previous Pi Pico port, especially if the SDK and hardware help to keep things compatible between the two boards.

Yes, it should be pretty straightforward.   It should also support quite a range of the boards using either of the pico chips.  See the list of boards here https://github.com/raspberrypi/pico-sdk/tree/master/src/boards/include/boards
