Tested on Ugoos AM6 (s922). Operation of the DDBR utility (creating and restoring a full copy of eMMC). Checked Armbian and LibreELEC installation in eMMC. On the first test version of u-boot in the firmware, there is a small bug, eMMC is defined as mmcblk0 , so when you install in eMMC you need to change the script "install.sh" number 1 to 0. By the time the product goes on sale, I think it will be fixed. The developers are currently testing a new version of the firmware, which immediately includes a universal multi-download by default. This means that users can run external systems without additional activation steps. This is the first set-top box, which will default to this mode. By the way, I really liked the cooling system AM6, the combination of a metal body and a large radiator to allow it to remove without altering the body at all of my loads. Again, this is the first TV box where I did not have to redo the cooling system. Also on the Board there is a connector for the fan, which can be used for special conditions, if you do not have enough regular cooling system (I have not checked it yet, maybe I will not need it).
