Requirements
Two files are required to bring up Newer model of Turris Omnia (Turris Omnia 2019 & Turris Omnia 2020)[Revision: CZ11NIC23
]
omnia-medkit-openwrt-mvebu-cortexa9-cznic_turris-omnia-initramfs_autoupgrade.tar.gz
Extract *.wic.gz image and rename to sysupgrade.wic. For example,
gunzip rdkb-generic-broadband-image_default_20200809095738.rootfs.wic.gz
mv rdkb-generic-broadband-image_default_20200809095738.rootfs.wic sysupgrade.img
Flashing RDKB image (A Yocto Project based Distro)
Flashing with Medkit & Sysupgrade images
NOTE: This upgrade procedure wipes out eMMC flash storage(/dev/mmcblk0) completely. Earlier partitions are lost.
Perform following steps to flash New Turris Omnia with RDKB image.
- Connect a USB flash drive to PC that is running Linux. Create a partition in flash drive and format the partition with mkfs.ext2
- Copy both attached medkit image and sysupgrade.img image to USB flash drive.
- Disconnect other USB devices from the Turris Omnia and connect the flash drive to either USB port.
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 check 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.
Creating additional partitions
Create partitions for /nvram and rootfs. Reboot the system.

Welcome to fdisk (util-linux 2.28.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

The partition table has been altered.
Calling ioctl() to re-read partition table.
Re-reading the partition table failed.: Device or resource busy
The kernel still uses the old table. The new table will be used at the next reboot or after you run partprobe(8) or kpartx(8).

RDK Firmware(Image) upgrade:
Approach 1:
RDK firmware upgrade with XConf server: Firmware upgrade through XCONF server - Turris-Omnia - User Manual - 2020 - M6
Approach 2(Quick):
Copy zImage and rootfs files from PC to /tmp/ directory of Turris Omnia which is running RDK Image
For example
scp zImage--4.14.22-r0-turris-20200720105910.bin root@<TurrisOmnia-IP>:/tmp/
scp rdkb-generic-broadband-image_default_20200720105910.rootfs.tar.gz root@<TurrisOmnia-IP>:/tmp/
In Turris Omnia, execute /lib/rdk/TurrisFwUpgrade.sh to flash new RDK image present in /tmp folder
sh /lib/rdk/TurrisFwUpgrade.sh
Turris Omnia will now run upgraded version of Yocto based RDK image.
