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.
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:

---|---|---|
| ||
ssh |
@192
root@192.168.1.1 |
Then, from the ssh session or a serial console:
Code Block | ||
---|---|---|
| ||
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.

Follow instruction from wiki page(https://wiki.rdkcentral.com/display/RDK/Wifi-Extender+Yocto+Build+Instructions) to make yocto's RDK-B image from yocto workspace in your PC.
Boot into openwrt based linux system in turris omnia board. Its downlink interface will have 192.168.1.1 IP address and have it connected to your PC.
Check whether 'fdisk' command is available in openwrt system. if it is not present, follow below steps to have 'fdisk' command.
