Wow,
I have uploaded the standard M5Unified Button code to my M5Core2.
I know the program is running because my serial.print shows button counts.
But the display shows nothing.
I have tried this on multiple Core2 of which I know the display is not defect. All boards and libs are updated (as fwr as i know).
What am i doing wrong here?
Thanks

M5.begin();
Serial.begin(115200);
/// For models with EPD : refresh control
M5.Display.setEpdMode(epd_mode_t::epd_fastest); // fastest but very-low quality.
if (M5.Display.width() < M5.Display.height())
{ /// Landscape mode.
M5.Display.setRotation(M5.Display.getRotation() ^ 1);
}
}
void loop(void)
{
M5.delay(1);
M5.update();
