Current status of external SPI SRAM support?

[fesp32@joov.de]

What is the current status of the external SPI SRAM support?

I am referring to the ''nice' way of connecting an SPI SRAM, supported by the MMU to make the SPI SRAM visible as normal RAM in the memory map.

In the errata document I can see that one problem may have been fixed, but a remaining one persists. But I cannot infer whether the feature is now usable or effectively unusable. What is the current status? Did anyone try this out?

Cheers,
Johannes

SPIRAM support is fully integrated into latest esp-idf master branch and latest xtensa toolchain.
I've tested it in complex application and so far it works without issues.

One bug is fixed in rev1 and the other is worked around in the newest compiler release.
