Hi Len, what about using du instead of df. Does the size of /tmp show up then?
I am at work logged in to a BBBlack running Ubuntu 13.04 and du does not show /tmp either. I really don't see any reason for it to be on a separate partition, maybe the Ubuntu developers didn't either.
Sorry for the long delay. So finally the arduino code is uploaded and I see the new cockpit and the statistics. Stefans solution worked however I had to put an & between all of the reset, sleep, and upload commands.
Now my issue seems to be I cannot control my motors at all. They are just constantly on. Thoughts?
