> Expressif does a fantastic job on documentation

As far as I know this took them a while to learn. In the beginning they were your typical weird chinese chip maker, but people volunteered effort into documenting their products because they were just that good. Now they've learned to do it themselves and can probably help M5 with it too.

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.
