Installation
Connect to one of LAN (yellow) ethernet ports,
Open router configuration interface,
Go to Toolbox > Firmware,
Browse for OpenWrt factory image with dlf extension and hit Apply,
Wait few minutes, after the Power LED will stop blinking, the router is
ready for configuration.
Known issues
Some USB 2.0 devices work at full speed mode 1.1 only
MAC addresses
factory partition only contains one (binary) MAC address in 0x4.
u-boot-env contains four (ascii) MAC addresses, of which two appear
to be valid.
factory 0x4 **:**:**:**:b9:84 binary
u-boot-env ethaddr **:**:**:**:b9:84 ascii
u-boot-env wanaddr **:**:**:**:b9:85 ascii
u-boot-env wlanaddr 00:AA:BB:CC:DD:12 ascii
u-boot-env iNICaddr 00:AA:BB:CC:DD:22 ascii
The factory firmware only assigns ethaddr. Thus, we take the
binary value which we can use directly in DTS.
Additional information
OEM firmware shell password is: SitecomSenao
useful for creating backup of original firmware.
There is also another revision of this device (v1 001), based on RT3352 SoC
The nvmem feature (commit 06bb4a5) was introduced in master after the
splitting of the 21.02 branch. It need to be reverted in 21.02..

[remove config DT label, convert to nvmem, remove MAC address
setup from u-boot-env, add MAC address info to commit message]
