Also late to get Legato SDK into life, he. Almost there, just intended to debug first example, I am running out of disk space on root fs. ```auto root@swi-mdm9x15:/opt/legato/apps# df Filesystem 1K-blocks Used Available Use% Mounted on

From looking at your logs, your /var directory seems to be taking up quite some space (15.1M) which is most likely why you are running out of disk space. Can you run du on that directory? Is this a fresh install of Legato? Can you run ‘app list’ on target to see what apps are installed? Did you copy any files onto the target? I took a quick look at 2-3 of my devices and these are the numbers I roughly see with a fresh install of Legato. `root@swi-mdm9x15:/var# du -h -d1 / 20.9M /usr 36.0K /media 0 /sys 1.5M /etc 4.2M /opt 1.4M /bin 4.0K /dev 3.4M /var 8.2M /mnt 4.9M /lib 0 /proc 1.8M /sbin 4.5K /boot 1.4M /home 4.0K /lost+found 67.0K /data 47.8M / ` ---

In the meantime, I’ve found 10MB file on /var/lib/rpm/log/log.0000000001. Not from me. In fact, this are my first steps into Legato world. Deleting this file did not solve much, as /var is in a separate mount. I had to delete /data/ring.wav (1MB), and now modemDemo seems to has enough disk space to install. I think, that clean flash kernel and rootfs, is correct way to go.
