Not sure is it best to ask this question here or on the Pinoromi forums! For this instance will try on both!

So just loaded the Micropython with the PSRAM image. Thanks you very much.
Could you explain / clarify exactly whats happening.

I see that there is now around 7.8MB of free memory (around 199K used of the PSRAM 8MB ?)
For the image without PSRAM I seen around 658K free, so around 62K of the 520K SRAM.

I am concluding that everything is being run from the PSRAM and the FLASH is not used after startup ?
If this is the case can you overclock with the limited speed of the PSRAM ?
Can you still access the onboard 520K of SRAM ?
Could you run the Python interperator in SRAM and user code in PSRAM?

Many thanks and regards
