I am trying to learn to use an ESP32-WROOM-32E board I just received. I installed the board in the IDE and a Blink sketch seems to compile OK but when upload is tried I get:
A fatal error occurred: Could not open COM5, the port is busy or doesn't exist.
(could not open port 'COM5': FileNotFoundError(2, 'The system cannot find the file specified.', None, 2))
Hint: Check if the port is correct and ESP connected
esptool v5.1.0
Serial port COM5:
Failed uploading: uploading error: exit status 2
Does anyone know what I should do?
