No I just need the SD card for storage, and I can't use the HSPI as I'm already using them for I2S.

I've got the card wired up and it still boots, but haven't yet started smashing code.

Keep me posted

EDIT: I was under the impression the ESP8266 only has a SD slave implemenation, so it can emulate an SD card (I guess with dynamic virtual values instead of real memory) but not control an actual SD card itself.

But I may be wrong of course.

Or are you using the SPI access feature of most SD cards? It seems it has a few quirks though.

But you may also be right - that's the fun and excitement of working with this module. It's a constant surprise hahahaha

Not quite what you want when you're trying to build commercial systems though!

I must say the ESP8266 is very interesting, it's really packed with interesting features. But the documentation is so very bad/lacking, that it often makes me want to give up. Often it's information Espressif could easily share (not sensitive in respect to business IP or WLAN regulations) but they simply refuse to do so. Also it must be very little efford to share those informations. Something like where the stack area is and how large it is, for instance.
