Sparkfun board fio v3 can't upload blinking sample code on ubuntu 14.04

Hello,

I really appreciate any kind of help.

This is my situation:

sparkfun fio v3 arduino ide 1.6.4 (last version available) last version of addon files available there (https://learn.sparkfun.com/tutorials/pro-micro--fio-v3-hookup-guide#installing-mac--linux). They have to work with ide version > 1.5. ubuntu 14.04 LTS

I can't upload the blinkies example code! When I started as root the arduino ide the following messages appear to me: " *avrdude: butterfly_recv(): programmer is not responding Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions. * ". In other occasions the uploading procedure doesn't finish and the red bar doesn't reach the 100% uploading condition (still remains in that position).

Any suggestions? I really want to fix this problem and I am quite new in arduino board programming. I have to use a less recent version of ide or addon? thank you so much!

Best regards

Were you able to locate and select the proper board after extracting the files into your Sketchbook?

Yes, I can select the sparkfun fio v3 board among the possible boards in the tools menu and also the available port 'COM4'. Other suggestions?

Thank you!

I shifted on Windows 7. Now I can upload for few times… But after some uploading the port wasn’t recognized anymore. If I try to open serial monitor I get the following error:

"Error opening serial port ‘COM4’. (Port not found)

Thank you"for any kind of help!
