Global state and running multiple Micropython interpreters on separate threads

[Robert-M-Lucas]

Hello, I want to run Micropython multiple times with separate states on separate threads. Is all of Micropython's state contained in mp_state_ctx and therefore would making it thread-local (including the changes required to make that work) be sufficient for this?

This is a rather advanced topic. So you might need to just try it out and report back what you find :)

I fear there would be a nest of potential issues around competition for resources: RAM, flash/filesystem, I/O devices - just to mention the ones that spring to mind. I would imagine you would need some kind of mini-OS to manage all the instances.
