Documentation for how to update IDF version

Forgive me if this is documented anywhere, I haven’t been able to find it. I frequently use new IDF features as they’re released and am trying to figure out how to build a custom platform-espressif32 using a specific SHA from IDF. I’m happy to help document and possibly automate this once I understand how to do it.

I see that there’s a builder/main.py script and a builder/frameworks/espidf.py script. My understanding is that those get invoked to build platform-espressif32 and framework-espidf respectively, but I don’t see anywhere that the actual IDF version, SHA, or local path gets set.

Looking at the framework-espidf package tar.gz files, it looks like it has pretty much all of IDF in there. I see IDF_PATH is set from FRAMEWORK_DIR, but I don’t see where the IDF files get into FRAMEWORK_DIR to begin with.

Help here would be much appreciated. And I’m happy to document this (maybe in the README) once we have a procedure worked out. @Jason2866 I know you’ve done this before (and thank you so much for doing it all those times!!) do you have the process written down anywhere?

IDF 4.4.2 is stable!

Sorry, my bad, I misread the issue. There is no precise ETA, but support for v4.4.2 will be added within next weeks.

@johnboiles I have changed in my espressif IDF fork esp-idf/releases the github actions workflow. A release Tag now generates a small release which can be used directly with platformio. No more manually work 😃
