Hi Robert, thanks for the quick reply.

Good NEWS - I figured it out!!!

The problem was that it seems the SW assumed I have QSPI PSRAM, but my board has OPI PSRAM.

I simply added this line that I found Dave using in another environment, and it worked!

board_build.arduino.memory_type = dio_opi ;Without this magic incantation, PSRAM will not work on this board

I only figured this out, because I saw the Arduino IDE Tools menu allowed you to select between QSPI and OPI PSRAM, so I figured there must be a way to do it in PlO, so I simply searched for "OPI" and found Dave's "magic" line.

Did you have to set this for your boards?

Andrew
