@frittna I'm trying to build the application using the Arduino interface and I get one warning:
WARNING: library Timezone claims to run on avr architecture(s) and may be incompatible with your current board which runs on esp32 architecture(s).
I read a few article that say it still works even though the warning is displayed so I continued to try uploading to my M5Stack
When I compile and upload it completes 100%
Hash of data verified.
Hard resetting via RTS pin...
However the M5Stack never does anything other than display a blank (black) screen.
Any thoughts on why that would happen?
