Problem with uploading

Hello, when I’m trying to upload my sketch console shows this error:
A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header
Failed uploading: uploading error: exit status 2


  • Did it work before?
  • Does RoboBoard X4 turn on and work?
  • Did you try using different USB cable, USB port or another computer?
  • Does new port appear in Arduino IDE Tools → Port menu, when you connect RoboBoard X4?
  • This happens when you selected that port and trying to upload the code?
  • What is your board version (v1.0 or v1.1) and which operating system are you using?
