Not enough space to install AVS

I have a respeaker core v.2. I have successfully followed the preparation steps and out of box demo. I was able to burn the image onto the SD card (16GB) and connect to WiFi. I am able to follow all of the steps up until this point

As I run the last command shown here ^^ I get an error that says there is not enough disk space. Error shown below

fatal error: error writing to /tmp/cce8hVfG.s: No space lef on device
} // namespace alexaClientSDK
^
compilation terminated.

My SD card has 16 GB on it, but when I run the command ‘df -h’, it looks as if it is not utilizing that space, but rather just the 4GB of eMMC.

“respeaker@v2:~/sdk-folder/sdk-build$ df -h

How can I either clear the eMMC, or make the device use the SD card for storage to run this command? Thanks!
