Zephyr with memory-mapped PSRAM

[jetpax]

I am looking to develop an app on MicroPython using the Zephyr port that requires a lot of RAM, eg PSRAM.

I understand that memory mapped PSRAM is supported on the Zephyr port, and that the STM32H7 is good, but RP2350 not (ie not memory mapped????)

Can anyone with direct experience confirm that and/or a recommend a suitable hardware platform to develop on?

I have found this STM32H7 board which looks good, and have also looked at this RP2350

Apart from QEMU, what are you all using for Zephyr development?
