Description of problem: When I try to upload a program to the "UNO" board, the operation fails wit this message: avrdude: Yikes! Invalid device signature. Double check connections and try again, or use -F to override this check. Version-Release number of selected component (if applicable): arduino-core-0021-1.fc14.noarch How reproducible: just load a simple program, compile it and try to upload to the UNO board Steps to Reproduce: 1. load/write a simple program 2. compile 3. upload Actual results: fail with this message: avrdude: Yikes! Invalid device signature. Double check connections and try again, or use -F to override this check. Expected results: the compiled program should be uploaded to the board Additional info: After some investigation, i've found the solution (from here: https://bugs.launchpad.net/arduino/+bug/529444) Just open /usr/share/arduino/hardware/arduino/boards.txt and modify uno.upload.protocol=stk500 to: uno.upload.protocol=arduino Detailed explanation in the previous link
Created attachment 470078 [details] a boards.txt file working Here's the modified /usr/share/arduino/hardware/arduino/boards.txt that does the trick
