It seems that the Chi.Bio are already set up software-wise from factory.
However, once logged in as root on the beagle board, the directory /root/chibio doesn’t contain any file.
One way we found to set things up is to copy all the files and directories from /home/debian to /root/chibio.
Once this is done, launching the command bash cb.sh initialises the beagle board correctly.
It might be useful to report this to LabMaker and to update the instructions on the website accordingly.
