6.2 Using a Raspberry Pi 1, 2, or 3 as a host

When using Raspberry Pi 1/2/3 as a host, perform the following steps to download, compile, and run the
"rpiboot" tool. This will make the Compute Module appear as a Mass Storage device. These steps only
need to be done once in order to make the tool. Skip to the last step if this has already been done.
Note: An Internet connection is required for these steps.
1. Open a terminal window and confirm that the internal date is correct by entering:
date
If the date is not correct enter the current date in a terminal window:
sudo date MMDDhhmm
Where MM is month, DD is day, and hh and mm is hours and minutes respectively.
2. Make sure the host system is up to date using the following commands in a terminal widow:
Note: These may take 10 or more minutes to complete. Answer "y" if prompted.
sudo apt-get update
sudo apt-get upgrade
sudo rpi-update
