Using interrupts and Pico 2nd core

[ZacharyInDallas]

I’ve read some comments about problems when trying to use that 2nd core of a Pico and interrupts at the same time.

Is this a bug, or just a lack of documentation that this is not possible?

Are their any plans to make this possible?

Is so, is there an estimate on when it will be possible?

Is there a thread I can follow to let me know when this is fixed?

Will it then work with PIO’s using soft interrupts?

I thought I had a receive PIO UART working reliably using interrupts on the 2nd core of a Pico a few months ago. I have revisited that code with a different version of MicroPython, and it doesn’t seem to work any more, MicroPython locks up. Was I just lucky it worked at all, or has something changed in MicroPython?
