Last time I worked with them there was an enormous gulf between the 1000+ pages of documentation you'd get from ARM. The ESP32 / ESP8266 documentation was pretty sparse and generally just high-level. I'd love to hear that's changed and that they now offer documentation closer to what you'd expect from "true" professional embedded offerings.

Edit: I took a look at the current ESP32 technical manual[0] as well as an example of Xtensa ISA documentation[1] - it definitely looks way more detailed than what I remember. I'd have a lot more confidence debugging weird behavior today -- it looks like I have enough to determine if there's a bug in my written/compiled code vs. a bug/discrepancy between the silicon vs. documentation.
