I can't confirm anything since I haven't yet received my Pico2, but the information you provide scares me a little - I'm in the beginning phase of a project where either Pico or Pico2 will have to be the SPI slave (Pi4 or Pi5 being the master) and I've got the first buffers sent - with problems, but I'm currently debugging the problems.
Is there a write-up of the original problem somewhere so I could read it like a civilized person and not hit it headfirst?![:)]( "Smile")
My program's current status - maybe a symptom of the problem you mention - the peripheral can hear the master loud and clear (test case: master sends buffers of "ABABABABA"). But the master can hear the peripheral only at the start of their session (2 buffers containing "ababababab" interleaved by a buffer of null, after that - endless buffers of null).
Example from bus master:
Example from peripheral:
(currently I just think my polarity and phase settings differ)
