I installed the CM3+ and got the image onto Norns fine, it boots fine, I did not break anything as well. Yay!!!
However I am lost with how to expand the disc usage of CM3+
What does this mean:
"to expand disk
sudo raspi-config
advanced > expand disk
reboot"
How do I do this? With the switch set to disk or to run?
I tried and I got an sudo: raspi-config: command not found
Thanks for helping me with this last step again.
(A few minor steps were missing in the scattered information, eg I did not have wget installed and needed to run brew install wget, also I had to run tar xzf norns190405.tgz to get the image file as I simply guess that .tgz would not be a valid file for an image)
