• upgrade through a "medkit" image through the use of a USB stick and pressing the reset button.
• https://openwrt.org/toh/turris_cz.nic/turris_cz.nic_omnia is not entirely accurate, and cannot complete without access to the serial port, due to an error in the factory initialisation of the U-boot environment. Updated procedure:
  • Remove the casing. Connect a TTL serial interface, see "Serial Port Access" above.
  • Format a USB flash drive as ext2.

  • Download openwrt-18.06.2-mvebu-cortexa9-turris-omnia-sysupgrade.img.gz and omnia-medkit-openwrt-18.06.2-mvebu-cortexa9-turris-omnia-initramfs.tar.gz from http://downloads.openwrt.org/releases/18.06.2/targets/mvebu/cortexa9/ and copy both files to the root of the flash drive.

  • Disconnect other USB devices from the Omnia and connect the flash drive to either USB port. (I have only verified this with the USB port at the front).

  • Hold down the reset button (backside, bottom centre) and plug in the power cord. Wait until the fourth LED lights up (green), then release (before the 5th LED lights up). _{Please click here to see more detail on rescue modes.}

  • Wait approximately 2 minutes for the Turris Omnia to flash itself with the temporary image, during which LEDs will change multiple times.

  • Either use the serial console, or connect a computer to a LAN port (LAN0 to LAN4) of the Turris Omnia with a DHCP client.
    From a computer:

    Code Block
    theme DJango
    ssh root@192.168.1.1

    Then, from the ssh session or a serial console:

    Code Block
    theme DJango
    mount /dev/sda1 /mnt sysupgrade /mnt/openwrt-18.06.2-mvebu-cortexa9-turris-omnia-sysupgrade.img.gz

  • Wait another minute for the final OpenWrt image to be flashed. The Turris Omnia will reboot itself and you can remove the flash drive.

  • After device reboot. You are now running stock OpenWrt 18.06.2.

•  Wouter Cloetens to provide an updated medkit image that fixes the U-boot environment, removing the need to open the casing and connect a serial port.

Approach 2(Quick):

Copy zImage, dtb file and rootfs files(not *dbg* rootfs file) from PC or VM to /tmp/ directory of Turris Omnia which is currently running RDK Image.

...

scp zImage--4.14.22-r0-turris-20200720105910.bin root@<TurrisOmnia-IP>:/tmp/
scp armada-385-turris-omnia.dtb root@<TurrisOmnia-IP>:/tmp/
scp rdkb-generic-broadband-image_default_20200720105910.rootfs.tar.gz root@<TurrisOmnia-IP>:/tmp/

...

Go back to OpenWrt OS (please refer Fallback to OpenWrt OS section above below ).

Have Ethernet connection from your PC to LAN port of Turris Omnia.

Keep rootfs(rdkb-generic-broadband-image_default_*.rootfs.tar.gz) and , zImage(zImage--4.14.22-r0-turris-*.bin) files and dtb file in home directory of your PC.
