> RP2354 has Flash finally The flash is QSPI, so its not really on die flash with a real flash controller. There is some QSPI cache but it’s really a band-aid solution to not having the real thing. People around the net don't seem to understand the difference and it can be very misleading. |

So I know that RP2xxx doesn't execute out of flash ever. I'm pretty sure the architecture of this is all execute out of SRAM.
Im pretty sure RP2040 copies out of QSPI and then executes in SRAM, but I'm not entirely sure what the downsides of this could be.
I'm guessing there might be security implications?
