Devices

  • imx6mm-evk
  • imx8mm-evk
  • imx8mp-evk
  • imx8mq-evk
  • bcm2711-rpi-4-b
  • stm32mp32mp157c-dk2

Steps to reproduce

  • Flash fresh build to the device. The build should not be the latest available one but at least the previous build.
  • Mask aktualizr-lite daemon in systemd by calling "systemctl mask aktualizr-lite"
  • Register the device with FoundriesFactory without starting aktualizr-lite daemon by calling "lmp-device-register --name --start-daemon=0"
  • Fill in the disk space entirely with dd. Create multiple files to be able to cleanup some room later. Example command, where X is a sequence number "dd if=/dev/urandom of=/home/fio/fileX bs=1M count=4000 status=progress"
  • After disk is full, start unmask aktualizr-lite daemon "systemctl unmask aktualizr-lite"
  • Start aktualizr-lite daemon "systemctl start aktualizr-lite"
  • Wait for the daemon to perform the OTA update attempt and watch the logs "journalctl -f -u aktualizr-lite"
