Hi, brand new to this game. I'm having issues uploading anything to a trinket board with an LED jewel attached. I have re-installed IDE etc. but keep getting this same error message. Can you point me in the right direction?

Many Thanks

This error indicates something has gone wrong with a hardware package installed via Boards Manager. The solution is to remove and then re-install the packages. Be aware this will remove any boards you have installed via Boards Manager:

  • (In the Arduino IDE) File > Preferences
  • Click the link on the line following "More preferences can be edited directly in the file". This will open the C:\Users\John\Documents\ArduinoData folder.
  • Delete all files and folders under the ArduinoData folder except for preferences.txt. Please be very careful when deleting things from your computer. When in doubt, back up!
  • (In the Arduino IDE) Tools > Board > Boards Manager
  • Wait for the downloads to finish.
  • Reinstall the boards platform for your Trinket.
  • Click "Close"

After that, try uploading again.

reloaded all boards now getting this message...

The current selected board needs the core 'arduino:arduino' that is not installed.

Error compiling for board Adafruit Trinket 8MHz.

Your installation of the Trinket board package is completely wrong.

Please provide a detailed description of how you installed it.

First off, Pert thank you for taking the time to help me, I really appreciate it.

I followed the following guides...

loaded the additional board manager url and then used the board manager to add the adafruit

Did you also follow these instructions: Arduino 1.0.x IDE | Adafruit Arduino IDE Setup | Adafruit Learning System and put some things in C:\Users\John\Documents\Arduino\hardware?

I just did a clean re-install and now I get this error...

avrdude done. Thank you.

Make sure you have the right board selected from the Tools > Board menu. There are different types of Trinkets.

Thank You for all of your help!
That did it.

You're welcome. I'm glad to hear it's working now. Enjoy!
