M5 Stick C Plus wont power on, but COM port exists
-
I left a speaker hat attached to an M5 StickC Plus, I'm not sure that's affected anything, but it seems to have drained the battery and now I cannot get it to power on.
To fix it I have tried:
[1] Attaching it to a PC via a USB cable. The COM port appears, I cannot upload code to it via the Arduino IDE. I get "Failed uploading: uploading error: exit status 2"
[2] Using M5 Burner. When I attach the M5 Stick M5 Burner reports that it has "Found new device". However, I can't flash it via M5 Burner and I can't erase it via M5 Burner. When I try it says "A fatal error occurred, the COM port doesn't exist"
[3] I have left it attached to 2 different chargers for 1 hour + each. Still no charge.
[4] I have tried attaching 3 x AA batteries to the 5v In and GND pins on the top header row. No change.
Is it completely dead? Any thoughts on what I can do to get it going again?
