It's a great work, but the original espressif/esp32-arduino-lib-builder has changed a lot in the new version of 2.0.5
I can't find the file system_api.c and CONFIG_FREERTOS_UNICORE in the new version.
Instead there is a same function in esp-idf/components/esp_hw_support/mac_addr.c
but I don't know how to choose the unicore option,please help.
