Hmmf, trying to find an easy way to get some extra ram (like 8-16 megabytes) onto an stm32 thing and all the options seem kinda annoying. QSPI PSRAM seems neat and would be fast enough but it can't be memory mapped R/W and somehow jlc doesn't seem to sell any psram? SRAM can be memory mapped but gets pretty expensive for that size. SDRAM is cheap and big but seems like a pain to route and I've never done that before. It also only available on the really big STMs…
Anyways, time to eep :neocat_up_sleep:

In response to this post@slyka wait, PSRAM can't be mapped RW? wat? how do you even use it at that point?
