What have you tried? What did Google suggest?
This query comes up 2-3 times a week !!
- Wrong board selected
- USB drivers not installed
- None gen board needing Ch340 driver.
- Duff cable
- Corrupt bootloader
Wrong speed selected (on boards where this is an option)
Board damaged in some way
Something connected to pins 0, 1, or reset
Driver issues or bad USB cable doesn't result in this error unless you've selected a port that does not correspond to the Arduino as a result of a port not appearing for the arduino.
