Failed to init external RAM (QEMU-84)

[0xPIT]

I try to test my code according to the documentation on this wiki.
The esp-develop branch of today can't seem to allocate PSRAM, see below.

E (2884) quad_psram: PSRAM ID read error: 0x00000000
E (2886) cpu_start: Failed to init external RAM!

Any tips on what I did wrong and how to resolve this?

Thanks

@0xPIT Sorry for the late reply. This seems to be happening with CONFIG_SPIRAM_SPEED_80M=y option set. Please use CONFIG_SPIRAM_SPEED_40M=y in the meantime as a workaround, when running the app in QEMU. I'll investigate how to fix this on QEMU side.
