@nano 在 Failed to send "Hello World" to M5stack with Arduino IDE on Ubuntu 17.10 中说：
hi, you can reference https://github.com/espressif/arduino-esp32/blob/master/docs/arduino-ide/debian_ubuntu.md
and delete the borad manager version.
Thanks for the fix! However, I tried to compile the Hello example with errors in Arduino IDE. Please take a look at the logs below:
Arduino:1.8.4 (Mac OS X), 开发板："M5Stack-Core-ESP32, 80MHz, 921600, None"
collect2: error: ld returned 1 exit status
exit status 1
为开发板 M5Stack-Core-ESP32 编译时出错。
I received this error too, I reinstalled a fresh version of all requirements (from thdirections linked) at least 4 times last night and could not get it working.
I ended up having to install platform IO which I do not understand, but at least I got it working!
hi, you can update the latest library https://github.com/m5stack/M5Stack.git
use the M5.powerOFF(); software way to turn off.
