So....that file wasn't actually there on my system.
A lesson in keeping up to date for me there.
All compiles now.
Really nice piece of work, especially like the OTA update functionality.
Thanks for the help.

Hi @Rop

I wonder if you could help me.

I am really looking forward to using M5ez but unfortunately I'm having problems compiling the examples and I'm getting persistent errors relating to any instance of println

This is a snippet of the error messages

Arduino: 1.8.5 (Mac OS X), Board: "M5Stack-Core-ESP32, QIO, 80MHz, Minimal SPIFFS (Large APPS with OTA), 921600, Debug"

<<<<AND SO ON WITH THE OTHER PRINTLN CALLS >>>>>>

Looks like I'm missing something from my environment but any ideas?

Many thanks
