Also, do you know how much space is needed to install rockpool?
I tried from scratch a second time and when I tried to clone the source-code it said there wasn't enough space on the disk.
Since I'm a Raspberry Pi novice I'm a bit confused because I'm using an 8GB SD card but after the rockpool installation failed, I shut down the Pi and took out the SD card and put it in my Mac and when I did a 'Get Info' on the disk it said capacity is only 62.9MB (Available 44.2MB). When installing Jessie, does it somehow bring down the capacity of the card??
