Re: Is the sockets API supported?

I haven't tried it, but the ESP IDF does build lwip/app/sockets.c which would suggest it is indeed available. Another item also pointing in that direction is the mbedtls component which typically uses the socket interface of lwIP.

Re: How does Flash Encryption (aka Secure Boot) work?

I haven't had time to dive into this yet myself, but the source in https://github.com/espressif/esp-idf/tr ... r/src/main would hopefully explain a few things.

Re: Interest in developer preview?

@igrr__: The RTOS SDK. I don't really consider it feasible to support a non-OS SDK ESP8266 and a RTOS SDK ESP32 in the same code branch. And the RTOS is much nicer to work with, even if it comes at a bit of a memory cost.

Re: Interest in developer preview?

Thanks for the update! At the moment it feels like the esp8266 and esp32 sdks are diverging rather than converging, and I'm trying to figure out the best way for the NodeMCU project to support both platforms with as little maintenance effort as possible. From a "lazy developer" point of view, I'd lo...

Re: [Documentation Release] ESP32 Technical Reference

Great start!

Feedback/Qs so far:

How does an external 16 MB flash get mapped into a 11512 KB window?

Typo: WDU => WPD ?

Re: Interest in developer preview?

Whoa... no kidding that things have changed! :)

This is going to take a while to digest...

@ESP_Sprite: Do you know if the ESP8266 will get a similar IDF (to replace the RTOS-SDK, perhaps)?

Re: ESP32 is finally real?

@Sprite_tm: I have a slightly unrelated question for you. Currently many of us use custom boot loaders and over-the-air firmware upgrade methods, typically by mapping either the first or second meg via Cache_Read_Enable() so we can have slot-agnostic firmware. Will the ESP32 have a similar capabilit...

Re: ESP32 is finally real?

Let's see... the way multicore processing is handled has changed (AMP -> SMP), the entire memory map has changed, we now have Newlib mostly in ROM (plus some other goodies), the GPIO block is changed wrt how you configure the functions, I2S has gotten a gazillion more functions... those are the thi...

Re: ESP32 is finally real?

The ESP32 SDK is SMP through and through and the ESP31s memory map doesn't lend itself nicely to that. Fair enough. I won't spend too much time trying to understand the cache window setup on the ESP31B then! Are there other areas that are likely to substantially change that I'd be better off avoidi...
