I'm looking for some more information when it comes to the STM32 OctoSPI support for Regular command versus HyperBus protocols when it comes to interfacing with an external PSRAM in Memory Mapped mode.We are considering a ISSI OctaRAM part vs HyperRA...

Thank you for the info, this helps. I ended up settling on a HyperRAM due to part availability at least for our first spin, so the question was mostly moot, but the errata document is very helpful.
