Re: Error compiling for board M5Stack-Paper.

I'm on Arduino 1.8.13, on a Win10 machine. I followed the procedure described in https://docs.m5stack.com/en/arduino/arduino_core2_development so using board definition at https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/arduino/package_m5stack_index.json

I'm on board version 1.0.7 bundled with xtensa
"version": "1.22.0-80-g6c4433a-5.2.0",
"name": "xtensa-esp32-elf-gcc"

I'm trying to compile rtc_wakeup example and get exactly same error reported in the linked topic.
