Hi, thanks for your feedbak 👍

esp32 support installed by boards manager.

Please check your package url Arduino Preferences (additional boards), it should be:

https://espressif.github.io/arduino-esp32/package_esp32_index.json

hal/cpu_hal.h: No such file or directory

this is a typical error when esp-idf version bundled with espressif core is too old, solution is to update the core to the latest version (2.0.9).

with the 2.0.9 - build ok.
thanks!
