Need help with Arduino as component for ESP32

[orbitcoms]

I followed the instructions and cannot get Arduino project to compile.
Using latest version of VSCODE, WROOM32 device, esp-idf extension v1.2.0, esp-idf version 4.3

I made changes to setup
- Autostart Arduino
- Disable Mutex locks for HAL
- Set FreeRTOS tick rate to 1000

I get compile errors related to I2C for some reason?

Hi there,

I have got the same problem plus one more build error for ETH.cpp when trying to add a Arduino core component to ESP-IDF in the VS Code ESP-IDF environment.

Here is the build log from ESP-IDF terminal after idf.py build.

It will be super helpful if someone could help looking into this.

Thanks!
