damn... now the confuse begins from start again want edit it but to late - you read my last (deleted) post
you can share only the data pins between psram and flash.
for flash you need own cs ( and clk )
and for psram you need own cs ( and clk )
the limits for clk is cause 80MHz / 40 MHz
sry for confuse

Can I confirm you are using a 10k pull-up on CS? I am as that was what was confirmed for me here...
viewtopic.php?f=12&t=6866&p=33097#p33097
But that also points to pins that cause the PICO to crash... so, um... confidence is low
I'm going to make a new RAM breakout and try that in case I damaged this one with all of my futzing around.
Thanks everyone for your help and PATIENCE with me... I am so far out of my comfort zone on this it's not funny... when @Matty suggested "lets throw some PSRAM on the TinyPICO" I thought to myself, how hard could that be??? hahahahha
