We have created an easy-to-use script to resize the flashed image on your device. Since the image is smaller than the storage device, it is not properly expanded when first flashed. You can run the following script to expand the filesystem.
This script should be in the home folder of the demo image. If it isn't there, or if you lost it and need it, it is linked below.
To run the script, run the following commands for the boot device you're currently using:
For eMMC:
$ sudo ./resizeDisk.sh eMMC
For SD card:
$ sudo ./resizeDisk.sh sd
Making the script executable
The script should be executable when it is included in the image. If it isn't, then you'll need to make it executable by running the following command:
$ chmod a+x ./resizeDisk.sh
Manually expanding space
If you don't want to use the script, you can run the commands below.
You may run into an issue where you run out of space on the eMMC or SD card when installing ROS. To expand the rootfs partition, follow these steps:
If you're on the eMMC, you'll use /dev/mmcblk2. If you're on an SD card, use /dev/mmcblk1. By default the NavQ boots from the included SD card in your kit.
$ sudo fdisk /dev/mmcblk1

Created a new partition 2 of type 'Linux' and of size 14.5 GiB.
Partition #2 contains a ext4 signature.

The partition table has been altered!
Once you're done with those steps, run this command:
$ sudo resize2fs /dev/mmcblk1p2
and reboot. You should now be able to install ROS Melodic without size issues.
