These steps are needed before attempting asterisk installation:

• Set your Odroid up with a static IP address
• set the ntpd to start and update the time
• Set a Super User Password
• Make a normal user
• Make sure you can SSH into the Pi.

Now log in as the super user (root) and stay in the root home folder (/root/). Everything we are doing here is done in bash. I suggest SSHing into it so you can copy and paste commands.

run the following command to stop the Odroid from booting into the GUI and hogging resources:

ln -sf /usr/lib/systemd/system/runlevel3.target /etc/systemd/system/default.target

Run fdisk

fdisk /dev/mmcblk0

Press the following commands:

• p(see starting block of p3, e.g. 1041016)
• d (delete)
• 3 (partition 3)
• n (new)
• p (primary)
• 3 (partition 3)
• 1041016 (starting block)
• <enter> (it will take ending block as end partition, so you have entire space)
• w (write partitions)

Upon successful editing of the partition resize the image to the partition:

resize2fs /dev/mmcblk0p3

Check the file system has been expanded:

df -h
