ESP8266_NONOS_SDK-3.0 Buil Fail

[pacmac]

I just updated to ESP8266_NONOS_SDK-3.0 using:

  git fetch origin pull/344/head
  git commit
  git checkout -b pullrequest FETCH_HEAD
  git submodule update --init
  make clean-sdk clean-sysroot all

Which I hope is correct, however now my build fails with:

.....

                 from ../../py/mphal.h:32,

      ^

Any suggestions on what the cause may be ?

I actually don't see any reference to etc_delay_* in espressif reference guide at all https://www.espressif.com/sites/default/files/documentation/2C-ESP8266_Non_OS_SDK_API_Reference__EN.pdf So errors seems logical, if they removed these

I think this might be related to https://github.com/espressif/ESP8266_NONOS_SDK/commit/4671b17cc9fc6ed6787c2d310daf8accccf29c8d, which is merged into nonos sdk v2.2.0+.

@pacmac Just FYI. I have built esp-open-sdk with esp8266 nonos sdk 2.2.1 and here is the change I need to make in micropython to get a successful build. I just got a build but haven't loaded it to my device.
