We have tried to set up a Chi.Bio from scratch, i.e. after reflashing it with the latest debian distro as explained in the software manual.

After flashing the beagle board successfully, and following the instructions in the software manual, we ran bash setup.sh.

Warning messages appeared for the python set up part of the setup.sh script.

After the setup.sh script finished (with various warning messages) the /root/chibio directory didn’t contain any file.

The only way to rescue things at this point was to copy files contained in /home/debian from a factory set up beagle board over in /root/chiobio.

We are not sure if we did anything wrong, however we tried several times following the instructions in the software manual, which resulted in the same outcome after execution of the setup.sh script.

This should probably be investigated, resulting in updates for the github files on https://github.com/HarrisonSteel/ChiBio and in updates to the instructions in the software manual.

Here is the message at the end of the process:

Installed /usr/local/lib/python2.7/dist-packages/Adafruit_BBIO-1.1.1-py2.7-linux -armv7l.egg

And here are some warning messages:
