Hello @jackchan000
ok, for some reason GPIO0 is held low causing the ESP32 starting up into download mode. GPIO0 is controlled by the USB serial chip inside M5Paper which in turn is controlled from the USB driver. (There is nothing much you can do to change that except maybe try a different computer.)
Try to power off and power on your M5Paper with the following steps:
disconnect USB press button in the back (this should power it off) Note: there is no visible change on the screen when doing that. press middle button on the side (this should power on M5Paper and run the factory test)Note: the button in the back has two functions depending on whether M5Paper is connected to USB or not.
reset (USB connected) power off (USB not connected)Thanks
Felix
