I got 2.9.4 to work, and it works just fine if you try to connect to a pc with a newer version of anydesk and viceversa. You can download it from:https://download.anydesk.com/rpi/anydesk_2.9.4-1_armhf.deb
Does anybody overclocked the Tinker Board running TinkerOS successfully? The datasheet of the system on a chip says that it can go up to 2.2 GHz. (http://opensource.rock-chips.com/images/4/4e/Rockchip_RK3288_Datasheet_V2.2-20170301.pdf At 1.2.5 (Overview.Features.System Component))
