Error when trying to upload to Uno Ethernet board
I've been trying to use my serial ttl camera with my Uno Ethernet board, up to this point the only thing I can get to work is the Comm tool. I've had the camera running well with an Uno board and all the sample files worked well with the Uno. One of the things I discovered is I didn't replace the "boards.txt" with the new one, so now that has been done. After replacing that text file I'm getting this error when trying to upload:
Binary sketch size: 18228 bytes (of a 32256 byte maximum)
avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override
I'd override the error, but do not understand how I can use the -F unless there is a command line means of uploading. Up to now, I've not been able to get the Snapshot and MotionDetect samples to work with this board.
