COMMON ISSUES

  • Check you have a COMMON GROUND where required.
  • Where possible use USB 2.0 ports or a USB 2.0 POWERED HUB to rule out USB 3.0 issues.
  • Try other computers where possible.
  • Try other USB leads where possible.
  • You may not have the correct driver installed. CH340/341 or CP2102
  • There may be a problem with the board check your wiring first.
  • Remove any items connected to pins 0 and 1.

COMPUTER RELATED

  • Close any other serial programs before opening the IDE.
  • Ensure you turn off any additional security / antivirus just to test.

  • You may be selecting the wrong COM port.
  • Avoid cloud/network based installations where possible OR ensure your Network/Cloud software is RUNNING.

Arduino specific boards

  • CH340/341 based clones do not report useful information to the "get board info" button.
  • NANO (Old Types) some require you to use the OLD BOOTLOADER option.
  • NANO (New Types) See the specific sections lower in the forum.
  • NANO (New Types) Install your board CORE's.
  • Unless using EXTERNAL PROGRAMMERS please leave the IDE selection at default "AVRISP mkII".
