@jaseg The cursed bit is that the stm32 OCTOSPI has prefetching and caching you can't disable (since it's meant for XIP on SPI flash), and a bunch of annoying errata.
@jaseg (also I looked into the FMC and it seemed harder to use for this purpose than the OCTOSPI, although at some point I may spin a test board and try it out if I have enough free IOs.)
