Support for the latest Arduino v2.0

[valeros]

The latest Arduino core adds support for ESP32S2, ESP32C3 SoCs and a great amount of new boards. Related issues:

• ESP32-S2 Upload via USB CDC without Manually Entering Bootloader #591
• Adafruit ESP32-S2 Feather wrong specification #557
• Add LittleFS and FFat filesystem support #570
• Is ESP32-S2 SPIFFS not supported with Arduino Framework? #546
• Requesting Support For MicroMod ESP32 Board #521
• Support for Adafruit MagTag ESP32-S2 board #609
• platformio-build-esp32*.py scripts do not respect upload.extra_flags espressif/arduino-esp32#5255
• Use correct object copy for TxtToBin #714

Hi all
Are there any plans for this feature? When will it be supported?

You might also want to take a look at espressif/arduino-esp32#5505 in regards to this.

I've been trying to understand how I can get Arduino v2.0.0 to work in PlatformIO because there are some important bugfixes in esp-idf v4.3 which I need.. I have tried building with Arduino as an IDF component but that only supports up to IDF v4.0 and is buggy. I can't think of a way to get these updates without a lot of rework on my project by converting entirely to IDF.

Maybe it is my lack of experience with the platform, but I am confused about what prevents us using Arduino v2.0 in PlatformIO, can you explain it for me?

Here's an example that may help you out. The relevant tidbits are in [esp32git] which just extends the [esp32] entry I have an overrides the platform until support is added. Note you'll have to still use Arduino IDE to build and upload LittleFS if you're using it.

Thanks for your response @forkineye !
I followed your advice and created a project with your suggestions but I am unable to get a simple project to build still in PlatformIO. Although it is compiling, it is not linking. I Can't see anything different in my configuration that would cause this. I wonder if your cached packages are older than that latest?
The project can be found here: https://github.com/olicooper/arduino-v2-esp32-platformio

Update

I found this: espressif/arduino-esp32#5436 (comment)
Which says to use branch feature/arduino-upstream instead of feature/arduino-idf-master.. which now compiles. I also had to delete the .vscode\c_cpp_properties.json file because this was causing the build to fail after updating platformio.ini multiple times.
I'll do more testing to confirm though.

When can this problem be closed

[sblantipodi]

many days passed since the Arduino V2 release... is there an ETA for closing this issue?

[atclarkson]

Is it released?

When I build using Espressif 32 (3.3.2) it still pulls in framework-arduinoespressif32 3.10006.210326 (1.0.6)

Any guesses as to what I'm doing wrong?
