Below is a link to the specifications for SDIO, this includes expected responses, power up sequences etc....

https://www.sdcard.org/developers/overview/sdio/sdio_spec/Simplified_SDIO_Card_Spec.pdf

would it be possible to connect USB-SDIO sort of adapter, to ESP, and boot sketches directly, without the need of uploading them?
This would speed up things in testing environment.

Some follow-up need since that Post on ESP32 Forum : http://esp32.com/viewtopic.php?f=2&t=73&p=285#p285

I read the post and got a kick out of all the sparring in the comments. Dirt cheap but so far, apart from that article (which could be a decent hack), all I have seen is how to make it more powerful. Since the necessary cables cost about as much as the board, the trick for me may be to get it to do anything without doubling the list price.


I ordered one for $5 and it was to come in on 18Dec. It was delayed and the company (Microcenter) emailed to say that they were sorry and that it would be in before the 25th and they were so sorry that they would give it to me for free - and it came in a few days ago and they did!

So, I guess the point of my post is that I got a Zero for Zero and, so far, have done Zero with it
