[M5Stack Core2 v1.1] COM port not found
-
Problem
OS: MacOS 13.6.3 (intel)
Application: M5Burner (latest version, on Aug 4)The serial port cann't display in M5Burner application.
Steps taken
-
Tried different IDEs, but nothing worked.
-
Switched USB cables, yet COM port was still not visible.
-
Attempt to turn the USB lead upside down when plugging into the device without success.
-
I quickly press the boot button and Serial port was able to display, but soon disappeared. I seize the opportunity to click "erase" button, but it still didn't work and show the following error.
Error message:
Erase Flash esptool.py v4.7-dev Serial port /dev/tty.usbserial-58640309931 A fatal error occurred: Could not open /dev/tty.usbserial-58640309931, the port doesn't exist
Solution:
After removing the base and battery, I tried the 4th option and successfully erased the firmware!!!
Question:
What are the possible casues of the issuse?
How to burn the fireware correctly?
What steps should be avoid? -
