I am currently having an issue of running my dragonboard headless through SSH. It seems to break my SSH connection at random times. I am running the latest Debian Stretch release for the DragonBoard on linaro’s website. I initially tried the latest release of Buster, however, it is extremely unstable. (ex. sudo apt-get upgrade results in a soft-bricked dragonboard!)
This was experienced on 2 dragonboards now, and it makes it impossible to run headless.
