UM2-rk3188

for my UM2 I switched to dtb cs968 via editing extlinux.conf This brought up wifi and shut off the non existent internal eth connection. I could connect and transmit data with wifi. It couldn't find a BT controller(builtin) though. It does have the ap6210 combo wifi/bt chip on the board. It didn't seem as stable as the ut2 dtb however. Although that could be because I was mucking around with other things.

Thanks for all the work here! I just cleaned off the dust of a ugoos UM2 clone rockchip 8133. It's running Armbian_22.02.0-trunk_Rk3188_bullseye_current_5.10.96.img off an SD card. (The Jammy version has similar issues) HDMI is good. BT no (Actually an external BT dongle appears to work) WIFi no USB dongle with Ethernet good Happy to throw stuff at it for testing. ********************* I was trying to get docker going. It has iptables issue NFT no protocol failed to create NAT chain DOCKER: iptables failed: iptables -t nat -N DOCKER: iptables/1.8.7 Failed to initialize nft: Protocol not supported I fiddled around abit without much success. I don't know much about kernel changes. Alternatives didn't help either. sudo update-alternatives --set iptables /usr/sbin/iptables-legacy sudo update-alternatives --set ip6tables /usr/sbin/ip6tables-legacy
