I’m playing around with a BeagleBone Black that I have and I’m trying to flash the onboard eMMC with a new Debian image. I’m using the Debian 9.9 2019-08-03 4GB SD IoT image from https://beagleboard.org/latest-images.
Everything works as I would expect. I can burn the image to a microSD card, boot from it, setup the flasher script, and reboot and it flashes the internal eMMC as expected. The problem is that when I boot from the eMMC there isn’t any space to actually do anything. Here’s the output of df. Is this expected on a fresh install of Debian? Do I need to use a smaller image?
debian@beaglebone:~$ df -h
