From the DTS posted in another thread here, the board looks to be running a 5.10 Linux kernel. OpenWrt proper runs much newer kernel versions, so the board looks to be running a vendor fork of OpenWrt branched of already a while ago.
Maybe they are planning to catch back up to regular/normal/mainline OpenWrt at some point.
