In case where the upload procedure with esptool.py starts successfully but fails as soon as the baud rate is set to the high baud rate selected in Tools menu, select a lower baud rate in Tools menu.

This can also be caused by how certain pins are wired, if pin 12 is high at boot, programming will also fail with this message.
