Thanks statorworks.
You have very interesting ideas and this is also areas I wish to explore too.
Some ideas I am considering as well, to implement micropython, some emulator, IOT peripherals, or basic disk operating system on it. So likely I would open source this to take in advice from all interested experts in these field to develop the potential of this board.
The external memories are on SPI serial bus, the RAM is actually a pseudo SRAM.
The interesting part about the board being able to use DMAs to transfer data around the SPI and other different peripherals.
It is also possible to replace the Flash chip with RAM chip to bring total Ram size to 16M bytes.
This board has pretty lot of applications
Cheers
